Most info here comes from Kevin Brown's book, but it seemed silly to put it as reference for almost every paragraph. Perhaps there is a better way?DanielDemaret 17:24, 1 April 2006 (UTC)

date of fleming's discovery

on the timeline here, it is shown as 1929, but in the penicillin article, it's 1928. Penicillin#History $[[Media:Insertformulahere]]$

The 1961 edition of Encyclopedia Britannica vol.9 p.371 Title: Fleming, Sir Alexander - states that his discovery of the antibacterial powers of the mold from which penicillin is derived was made in 1928 and was a "triumph of accident and shrewd observation." The entry goes on to state that he published his results in the Journal of Experimental Pathology in 1929. Spyglasses 10:00, 8 January 2015 (UTC)

another father of penicillin

A Romanian bacteriologist, Victor Babes (1854-1926) has also been credited with the discovery of penicillin, before Fleming. I don't have an online reference though... 160.39.48.173 (talk) 20:06, 16 March 2009 (UTC)

Events in the Article

following the timeline here I have read now the personal Articles of John Tyndall and Joseph Lister. In both Articles the Relationship to this Events is not mentioned with a word. -- Hartmann Schedel (talk) 18:55, 15 June 2009 (UTC)

Fleming

According to a PBS program on this subject, Fleming did not advocate treating humans directly with penicillin, because he was one of the doctors who had shown the the use of the older antiseptics on war woulds did more harm than good. This is an important point, because it indicates that he did not discover it as a medicine. This is a case, like the recent CCD Nobel prize, where the main credit went to the basic researcher rather than the one who found the important application of the discovery. David R. Ingham (talk) 22:12, 7 June 2011 (UTC)

I think David R. Ingham or PBS misunderstood Fleming's concern. Yes, he (and others of his time) thought it unlikely that an chemical could be both antibacterial and non-toxic. Although Paul Ehrlich's arsphenamine was known, it was also difficult to use and not non-toxic. It wasn't until after Prontosil and sulfanilamide were discovered that the idea of safe and effective antibiotic therapy was widely accepted. Nevertheless, Fleming did do what we today would call PK and drug stability tests, with very discouraging results. It was the latter that likely discouraged him from testing penicillin in a challenge test. Reference: Macfarlane, G. "Alexander Fleming in Fact and Fantasy" New Scientist Mar 1, 1984, pp. 26-28. --Zeamays (talk) 20:04, 28 September 2011 (UTC)

Frederick S Dennis, 1885 (New York); Polotebnov, Manessien, 1872 (Russia); Other Russians

Milton Wainwright, Miracle Cure: The Story of Antibiotics, Blackwell, (1990), page 35, mentions Frederick S Dennis. As I recall from having dug out the original papers, Dennis was a surgeon or dentist who presented his study of Penicillium molds at a scientific meeting and included a display of test tubes with various organisms and results showing inhibition in the presence of P. molds.

Wainwright also mentions some early Russian claims but I have never been able to locate the source documents (even with the help of a Russian colleague in Moscow):
Polotebnov, Manessien, 1872 (Russia)
Lebedinskii, 1877 (Russia)

Factual accuracy tag

The article presents a long list of people observing bacterial growth being inhibited by molds and antedotes about ancient societies using mold to treat infection. But there is not evidence presented that any of this has anything to do with penicillin.

Not all molds produce penicillin. Not even all penicillium strains do. If they do demonstrate antibacterial activity, it is in many cases due to antimicrobial substances other than penicillin. And the examples of ancient treatments of infection using mold do not provide any evidence of efficacy to back up the claim that the molds actually had antibacterial activity. Phlebotomy was used to treat all manner of illness for over a millenium, and we all know that it doesn't do anything.

Its an interesting history, but none of the information in the article persuasively demonstrates that Fleming was not the first to demonstrate the antibacterial activity of what is now known as penicillin. Formerly 98 (talk) 02:14, 20 June 2014 (UTC)

Penicillin is like ANY invention -- once it has been discovered, you can point to a million other bits of prior art and say, Tut tut, it was OBVIOUS. That's what the Patent Office tries to do to you when you apply for a patent; they just Google for the words you use to describe your invention/discovery, and off they go. I have a special feeling for Dr Fleming and his discovery, since I discovered a cure for bladder infections that's the next thing after penicillin. But this "obviousness" thing is the bane of patenting nowadays; it's the principal test the USPTO employs, as I understand it. This article on History of Penicillin is a great example reaching back to the days before we even knew about microbes, much less had seen them. It's almost but not quite as bad as having to deal with the cranberry people, with the UTIs. Richard8081 (talk) 20:40, 16 July 2014 (UTC)

I agree. How about this replacement?

"but he was not the first to use its properties in medicine. " might be replaced with "he may not have been the first to use its properties in medicine. This is a list of prior incidents similar cases, although there is no conclusive evidence that the same substance was used."

There are many articles suggesting that he may not have used it first. This way, that issue is addressed, at least. " Star Lord - 星爵 (talk) 11:58, 20 November 2016 (UTC)

Merge proposal

The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section. A summary of the conclusions reached follows.

Not done. There is some interest in moving history info from the penicillin article to here, but this would merit broader discussion at that article. Ajpolino (talk) 21:14, 2 May 2018 (UTC)

---

This article doesn't really seem to fit the title. Everything before 1870 is about the history of using fungi as antibiotics. Everything from there to 1928 is about antibiotic properties of certain Penicillium species. It's not until maybe 1920 and after that the events are actually about the history of penicillin. The penicillin article actually has a pretty great history section. Maybe we could merge this article into that history section, as well as a section on the Penicillium page about "History" or "Role in medicine" or something. Thoughts? Ajpolino (talk) 04:47, 14 March 2017 (UTC)

I'd be fine with a merge. It looks like the majority of the information in the History of penicillin article is already in the history section of the Penicillin article, so a merge wouldn't even be that great of a change. One thing we would want to consider is how it would affect the Penicillin article. Would we include the table, or just insert information that wasn't already in the penicillin article? The history section of the penicillin article is also pretty long, so a couple people may raise the issue that content should be moved from the history section to the history article. That's also legitimate, but I think the current merge proposal is fine. I'll notify the talk page at the Penicillin article so that anyone watching the page will know that this discussion is happening. Icebob99 (talk) 19:26, 14 March 2017 (UTC)

Pasteur and penicillin

The situation described in the outline reads like a variation of the following incident described in Paul de Kruif's 1926 Microbe Hunters:

"He had not the precise methods of growing microbes pure—it took the patience of Koch to devise such things—and one day to his disgust, Pasteur observed that a bottle of boiled urine in which he had planted anthrax bacilli was swarming with unbidden guests, contaminating microbes of the air that had sneaked in. The following morning he observed that there were no anthrax germs left at all; they had been completely choked out by the bacilli from the air.

At once Pasteur jumped to a fine idea: “If the harmless bugs from the air choke out the anthrax bacilli in the bottle, they will do it in the body too! It is a kind of dog-eat-dog!” shouted Pasteur, and at once he put Roux and Chamberland to work on the fantastic experiment of giving guinea-pigs anthrax and then shooting doses of billions of harmless microbes into them—beneficent germs which were to chase the anthrax bacilli round the body and devour them—they were to be like the mongoose which kills cobras. . .

Pasteur gravely announced: “That there were high hopes for the cure of disease from this experiment,” but that is the last you hear of it, for Pasteur was never a man to give the world of science the benefit of studying his failures."

Is Pasteur's supposed "discovery" of penicillin a mangling/misunderstanding of this incident?

It is clear that in this incident had nothing to do with mold and based on Kruif's timeline it appears to be in the right time.--Professor Phantasm (talk) 23:38, 2 September 2018 (UTC)

Early research

Thanks for this addition, Swinkleman. To hopefully make it a little clearer, I've re-worded to

In the early stages of penicillin research, most species of Penicillium were generally referred to as Penicillium glaucum, so we cannot identify the actual strains used. Thus, it is difficult to tell whether it was really penicillin preventing bacterial growth.

Can you please confirm whether this preserves the intended meaning? I can't read the cited source as it is not in English. Adrian J. Hunter^{(talk•contribs)} 01:22, 9 March 2019 (UTC)

Yes, thank you for the edit. Adrian J. Hunter I'll see if I can fix the source.Swinkleman (talk) 18:50, 11 March 2019 (UTC)

New Edits

In the next few weeks I will be adding a lot of information about the manufacturing process of penicillin and its evolution over time.RandyGreeves (talk) 15:49, 5 April 2019 (UTC)

I am about to add to the First Isolation and successful treatment section Swinkleman (talk) 15:24, 12 April 2019 (UTC)

Penicillin

I added a new section about penicillin resistance. Antibiotic resistance is a new problem that arose with the use of penicillin.

I moved a sentence from Stabilization and mass production to this section, and added some info to the section. — Preceding unsigned comment added by Swinkleman (talk • contribs) 17:32, 12 April 2019 (UTC)

Early history of Penicillin

Hi, I want to note that the phrase "John Parkinson, King's Herbarian, who advocated the use of mold in his book on pharmacology." was referenced using a secondary paper from "Kate Gould, Antibiotics: from prehistory to the present day, Journal of Antimicrobial Chemotherapy, Volume 71, Issue 3, March 2016, Pages 572–575, https://doi.org/10.1093/jac/dkv484". I revised the online version of the original book here "https://www.biodiversitylibrary.org/item/256142#page/13/mode/1up", and I couldn't find the claim or the original "advocation" of John Parkinson. If someone has better research skills, please edit the sentence because it doesn't seem to be reliable. Thank you. Mycoandres (talk) 00:11, 28 February 2022 (UTC)Mycoandres

Very good information. It seems that Parkinson did not specifically mention moulds as medicinal; but later (modern) inferences indicate that some medicinal practices he described were based on Penicillium mould. For early description, see Cranch, 1943, JAMA. Chhandama (talk) 05:31, 1 March 2022 (UTC)

However, neither are primary sources who back-up the claims. I strongly suggest delete or add a tag of warning, because none of that "In England in 1640, the idea of using mould as a form of medical treatment was recorded by apothecaries such as the botanist John Parkinson, who documented the use of moulds to treat infections in his book on pharmacology. In 17th-century Poland, wet bread was mixed with spider webs (which often contained fungal spores) to treat wounds. The technique was mentioned by Henryk Sienkiewicz in his 1884 novel With Fire and Sword." is real documented history or primary sources. Mycoandres (talk) 23:46, 20 September 2023 (UTC)

So you looked up the sources and what did they say?

Source: " This theme of the benefit of moulds continued over the years, with references by John Parkinson (1567–1640) (Figure 1) in his book Theatrum Botanicum, published in 1640"

Article: "In England in 1640, the idea of using mould as a form of medical treatment was recorded by apothecaries such as the botanist John Parkinson, who documented the use of moulds to treat infections in his book on pharmacology."

---

Source: "Anyone who reads the Trilogy of Henryk Sienkiewicz knows, that in the former Poland wounds were treated with bread kneaded with spider's web. And on spider's web, of course, there are plenty of fungal spores, also Penicillium. So antibiotic treatment has been used in our country for centuries"

The isolation section is too brief

Considering how important is this part of the 12-year-long penicillin epic, the section is surprisingly short, almost shorter than Alexander Fleming#Purification and stabilisation. Could someone with a better knowledge of the subject than me please at least copy everything which is possible from there and add some more details on why it was possible in 1939 to do what Fleming and his colleagues struggled with for years before? Ain92 (talk) 14:54, 7 June 2022 (UTC) PS TIL about "penicillin girls".

I have expanded this section. The reasons though are: (1) Florey was a first rate scientist while Fleming was an ordinary one; (2) he assembled and directed a team of experts on a concerted attack on all aspects of the problem; (3) who persisted until they succeeded. It is worth noting that Fleming and his associates did not struggle "for years" but gave up after just one. Hawkeye7 (discuss) 02:28, 11 April 2023 (UTC)

Comments

On first read, this is a hugely comprehensive article and does a good job of telling the story clearly, even to someone with relatively little grasp of the technical details. Considering its immense length, I am impressed by the quality and accuracy of the prose. Most of the below are points of grammar or clarity: I'll do an image review and source checks once I've gone through the text. UndercoverClassicist (talk) 15:40, 6 July 2023 (UTC)

Thanks for taking on a major assignment. I had considered splitting the article in two. Hawkeye7 (discuss) 22:47, 6 July 2023 (UTC)

OK, that's the first pass done. I still need to do spot-checks for TSI, CLOP and so on, but that's probably best left until after the comments below have been dealt with to the extent that they're going to be. Again, nice work. UndercoverClassicist (talk) 20:23, 9 July 2023 (UTC)

Lead which he named penicillin in 1928: italicise penicillin per MOS:WORDSASWORDS. Y Because of the proximity of so many italics for Latin words, I have exercised the MOS alternative of quotation marks.

Y Changed as suggested. Hawkeye7 (discuss) 22:47, 6 July 2023 (UTC) Third paragraph: three consecutive sentences start with They [verbed] (two are they developed) - consider mixing up for elegance. Y Re-worded to make it more elegant and reduce the use of "developed". The triple "they" here is deliberate, though, a form of repetition as a rhetorical device. Hawkeye7 (discuss) 22:47, 6 July 2023 (UTC) I'm not sure that rhetorical device is really right for an encyclopaedia – it reminded me a little of Pericles's Funeral Oration – but style is almost a non-issue for GA. UndercoverClassicist (talk) 07:34, 7 July 2023 (UTC) Ten years later, in 1939: suggest simply in 1939; the previous events were in 1928, so 1939 seems like 11 years later to me. The text wanted to emphasises that nothing happened for ten years. This was something that Fleming and others tried to hide. Without this it might appear that he worked on it until 1939.

If so, the comma should be removed. Y Yes, it was. Deleted the comma. I personally think it is is fine, but whatever. Hawkeye7 (discuss) 22:47, 6 July 2023 (UTC) cultures of the anthrax bacilli: I may be wrong, but think this should either be of anthrax bacilli or of the anthrax bacillum. Y I don't know either.

As a research scholar, you work with professors and other professionals in your field of study and focus on uncovering new information that can be published in academic or trade journals. Hawkeye7 (discuss) 23:49, 6 July 2023 (UTC) Fair enough. My academic background is in old-fashioned places, where they have "[Junior] Research Fellows" as something analogous to a postdoc; you'd describe a person as a JRF but not normally as someone's JRF ("she's a Research Fellow in the Department of Engineering", but not "she's Prof. Smith's Research Fellow"). Is "research scholar" used in that way in sources, particularly British English ones? UndercoverClassicist (talk) 07:34, 7 July 2023 (UTC) It is what the sources say.

Hawkeye7 (discuss) 23:49, 6 July 2023 (UTC) I'm afraid the complete sentence no longer makes sense to me: Moving on to ophthalmia neonatorum, an eye infection in babies, he achieved the first cure on 25 November 1930, four patients (one adult, the others infants) with eye infections.: did he cure one case of ophthalmia neonatorum on 25 November, and subsequently cure (three, four?) other patients with (different) eye infection?

Is this now the general view on what happened? If not, and de Kruif's idea is a minority view, I think this placement gives undue weight to it; a footnote might be more appropriate. Is Microbe Hunters a book? Y Yes, it is a book. It is in the References. Deleted the assertion that Pasteur thought it was a mould, which is not supported by the sources. Hawkeye7 (discuss) 22:47, 6 July 2023 (UTC) I'd go with de Kruif's 1926 book Microbe Hunters, then. My DUEWEIGHT worry remains: what's the general view of de Kruif's idea today? UndercoverClassicist (talk) 10:05, 8 July 2023 (UTC) Y I think there is a misunderstanding here. The point is that Pasteur noticed an antibiotic reaction, but did not attribute it to mould, but to the action of bacteria (a reasonable but incorrect guess). Re-worded to make this point clearer. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) As this article's subject has strong national ties to the UK (WP:ENGVAR), I'd advise against the Americanism vacation. In the UK it means a university teaching break. So the usage is correct here. I could change it to "the summer break". Hawkeye7 (discuss) 23:49, 6 July 2023 (UTC) I think "the summer break" is a good idea; we do use vacation (certainly at old-fashioned places) for the university breaks, but you'd almost certainly specify in that context ("Hawking spent the Michaelmas Vacation in London", or "after the Lent Term, Crick worked through the vacation"): you wouldn't use it, as here, non-specifically as "a vacation". UndercoverClassicist (talk) 07:34, 7 July 2023 (UTC) Y Changed to "summer break". Hawkeye7 (discuss) 21:39, 11 July 2023 (UTC) The original colony of this mould, which proved to be Penicillium notatum, [sic]: is the sic because it wasn't, in fact, P. notatum? Before the comma, if so, but as this is a factual mistake rather than a grammatical one, I'd suggest replacing with an explanatory footnote. Deleted. Hawkeye7 (discuss) 23:09, 9 July 2023 (UTC) Is it true, as the article suggests, that the mould was not in fact P. notatum? If so, I'd certainly use a clarifying footnote so that we can report the original belief without misleading the reader. UndercoverClassicist (talk) 21:42, 10 July 2023 (UTC) The article does not suggest it, it explicitly states, backed up with a reliable source, that "Whole-genome sequence and phylogenetic analysis in 2011 revealed that Fleming's mould belongs to P. rubens". But this was not known until 2011. I don't see the need for a footnote along the lines of "as noted above, in 2011 Fleming's mould was found to actually belong to P. rubens". Hawkeye7 (discuss) 21:39, 11 July 2023 (UTC) This is now in another article, so the point is moot for present purposes. UndercoverClassicist (talk) 09:32, 12 July 2023 (UTC) Isolation Explain briefly what a bacteriophage is, as it's important to what follows. Y Not really, but added. The importance here is that a sample of penicillin was on hand when Florey decided to research it. Hawkeye7 (discuss) 00:20, 7 July 2023 (UTC) I'm not sure on the logic as to when sums of money are given with or without their present-day equivalents: I'd suggest using some sort of consistent system here. Some editors thought that there was no need for multiple ones near each other. Added a couple more. Hawkeye7 (discuss) 00:20, 7 July 2023 (UTC) I'd briefly explain why ether is/was so dangerous before talking about a "much less dangerous" chemical. Y "Ethers have a long history of causing laboratory fires and explosions." They also have been known to cause deaths from exposure. Hawkeye7 (discuss) 00:20, 7 July 2023 (UTC) Most laboratory containers did not provide a large, flat area, and so were an uneconomical use of incubator space, so glass bottles laid on their sides were used: I'm not sure I fully understand this, but perhaps it would help to know what shape the incubator was? There's a image. Hawkeye7 (discuss) 00:20, 7 July 2023 (UTC) Yup: my issue is that glass bottles laid on their sides don't provide a large, flat area either, so I'm not sure how the two halves of the sentence go together. Images are fine but shouldn't be used for anything it's essential that the reader understand, since some of our users can't access them (e.g. because of visual impairments, or because they use the auto-censor which defaults to blurring them). UndercoverClassicist (talk) 10:05, 8 July 2023 (UTC) Y I have linked to the article on incubators. An incubator looks like a refrigerator. I have made the point clearer. A description of the containers follows in the next sentence. Works well as reordered. UndercoverClassicist (talk) a brief note as to why 37°C is a sensible temperature for this? More widely, the article is inconsistent about whether to use (and convert) Celsius or Fahrenheit. Y All measurements are in metric, per MOS:METRIC. Where the source is an imperial measurement, a conversion is provided. Hawkeye7 (discuss) 00:20, 7 July 2023 (UTC) I've made this point later on, but I'd advise giving the sourced number first, even if it's imperial: converting implies rounding, and it's more honest to say that Fleming measured someone's height as six foot three (which is what actually showed on his tape measure, what he read out and what he wrote down) and then convert into cm for the reader's benefit.UndercoverClassicist (talk) 08:35, 8 July 2023 (UTC) It would be my preference too, but MOS:METRIC says to use metric first. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) So it does - all's well here, then. UndercoverClassicist (talk) 14:42, 9 July 2023 (UTC) The passage on Florey's application to the Rockefeller foundation could be trimmed for excess detail. This becomes very important later on. Hawkeye7 (discuss) 00:20, 7 July 2023 (UTC) Having now read on to the point where it does, I see what you mean. However, I'm not sure we really need the whole of this: Florey felt that more would be required. On 1 November 1939, Henry M. "Dusty" Miller Jr from the Natural Sciences Division of the Rockefeller Foundation paid Florey a visit. Miller was enthusiastic about the project. He encouraged Florey to apply for funding from the Rockefeller Foundation and recommended to Foundation headquarters in New York that the request for financial support be given serious consideration. "The work proposed", Florey wrote in the application letter, "in addition to its theoretical importance, may have practical value for therapeutic purposes." His application was approved, with the Rockefeller Foundation allocating US$5,000 (£1,250) per annum for five years. To me, the key facts here are that Florey received the grant, that Miller initiated and supported it, and perhaps that Florey was already looking on to clinical applications. We could do something much more concise like: Florey applied to the Rockefeller Foundation for funding, on the encouragement of Henry M. "Dusty" Miller Jr from its Natural Sciences Division. Florey's application, which predicted that penicillin research could have therapeutic as well as theoretical value, was supported by a recommendation from Miller to the foundation's headquarters in New York. The foundation approved the request and allocated the research US$5,000 (£1,250) per annum for five years. Not in itself a major issue, but given the length of the article, it's a good idea to cut for readability and approachability where we can do so without making major sacrifices. UndercoverClassicist (talk) 20:23, 9 July 2023 (UTC) Y trimmed. Hawkeye7 (discuss) 23:09, 9 July 2023 (UTC) Trials Florey's team at Oxford showed that Penicillium extract: to be clear, this extract is not the same as penicillin? Fleming called the mould extract "penicillin", but Florey used "penicillin" to mean the active ingredient (which Fleming had not isolated). Later St. Mary's would attempt to use this to confuse people. and noted that it was not an enzyme that broke the bacteria down, nor an antiseptic that killed them; rather, it interfered with the process of cell division.: this could do with a slight rephrase for clarity: it's a bit of a garden-path sentence where we initially read "it was not..." to mean "it was not [the case that...]" ("it's not the size of the dog in the fight..."), but it's later revealed to refer to penicillin. Suggest "they determined that penicillin was not, as previously thought (?), an enzyme that broke the bacteria down, nor an antiseptic that killed them; rather, it interfered with the process of cell division." Y Tweaked the wording along the lines suggested. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) What's a sulphonamide: for us non-chemists, why is it being mentioned here? Y Added a quick explanation. Linked to a better article. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) show that penicillin is active in vivo against at least three of the organisms inhibited in vitro: either both or neither of in vivo and in vitro should be italicised. Y (Has a look.) Florey does not italicise; seems to have been the work of a wiki-gnome. De-italicised. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Is it worth explaining briefly what The Lancet is: in particular, that it's an extremely prestigious journal, which might make the muted reaction to the publication a bit surprising? Y Added that it was "a prestigious medical journal", with supporting citation. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) The publication of their results attracted little attention; Florey would spend much of the next two years attempting to convince people of its significance.: presumably, Florey was interested in the significance of the results rather than of their publication: if so, their significance. Y Tweaked wording. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) The Columbia team presented the results of their penicillin treatment of four patients: we've met two (Alston and Aronson) already, but where did the other two come from? Y See Hobby, pp. 72-73. Two patients with endocarditis. One is just called "Mr Conant" and the other is unnamed, altough the treatment and dosages received is described in detail. Added a bit. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) We wouldn't normally mention a journalist's name (rather than the newspaper's) in connection with a report, but is William Laurence a big enough deal to make an exception? Hell yes! The most famous science reporter of the era, perhaps of all time. I encountered him on the Manhattan Project articles. He was present at the Trinity nuclear test for which he wrote the cover stories and flew on the Nagasaki mission as an observer. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) who had had a small sore at the corner of his mouth, which then spread: suggest clarifying the chronology here: by the time we're talking about, he no longer had a small sore. Maybe something like "who had a severe facial infection involving streptococci and staphylococci which had developed from a small sore at the corner of his mouth"? UndercoverClassicist (talk) 08:32, 8 July 2023 (UTC) Y Changed as suggested. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) 100-millimetre (4 in): presumably, the measurement was originally given as 4in? If so, I'd give that measurement in the main text, then convert in brackets, to indicate that 100mm is the rounded figure. Likewise for other cases where the source gives an imperial measurement. As noted above, the MOS says otherwise. See consensus with an RfC. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Yes, happy that this is solved as above per MOS:METRIC UndercoverClassicist (talk) 14:42, 9 July 2023 (UTC) Who was Sir Percival Hartley? Another Florey point here: which one? Y Added a bit about him. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) One reader was Fleming, who paid them a visit on 2 September 1940. Florey and Chain gave him a tour of the production, extraction and testing laboratories, but he made no comment and did not even congratulate them on the work they had done: clearer, I think, if we use Florey and Chain's names where we currently have them, and then they later on. Suggest deleting even as a sort of weasel word (it makes a moral judgement that he should have congratulated them, which isn't a verifiable statement). UndercoverClassicist (talk) 20:23, 9 July 2023 (UTC) I see why Mary Ethel Florey isn't referred to as Florey, but using her first name only is odd and has the unfortunate consequence of applying less formality to her vs. her male colleagues. Suggest "Mary Florey" vs. "Howard Florey", which can then be "Mary" and "Howard" if mentioned again within the same passage. Ethel was placed in charge, but while Florey... is unclear. Y Changed to Howard Florey here, but elsewhere "Florey" is understood to mean Howard, and it would be awkward to keep repeating his first name. Note that Margaret Jennings was also Lady Florey. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) I'm not sure about 'is understood': you might understand that, but I don't think we can rely on all of our readers making the same assumption. One option would be to footnote it: otherwise, I'd suggest using "Howard Florey" or "Ethel Florey" (or indeed "Lady Florey") the first time that one of them is mentioned in a given passage or chunk of text; as long as they're the only Florey in the area, they can then be "Florey" until the next long break. UndercoverClassicist (talk) 20:23, 9 July 2023 (UTC) I guess we could delete all mentions of Ethel Florey, but I didn't really want to do that. Hawkeye7 (discuss) 23:38, 10 July 2023 (UTC) That wouldn't be at all necessary: we just need to name her and her husband in a way that's clear and close enough to neutral with regards to gender. There's plenty of ways to do it, but I don't see that the suggestion I made above would be particularly difficult to implement. UndercoverClassicist (talk) 11:00, 11 July 2023 (UTC) Y The first mention of Florey in each section is "Howard Florey", except in the sections where Ethel Florey is mentioned. Hawkeye7 (discuss) 21:39, 11 July 2023 (UTC) Deep submergence for industrial production in a confined laboratory: I'm not totally clear on this; does confined really mean small? Y Not really. Deleted "confined". Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) was losing a battle against: metaphorical language like this should be avoided in encyclopaedic writing. Y Re-written. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) What was wrong with John Fulton, or was Bumstead simply his family doctor? Y Treating his for an infection. Added. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) about 3 grams of penicillin was recovered: were recovered, I think. Y Changed as suggested. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) I think shallow pan method would usually be hyphenated: it's the pan that's shallow, not the method, so shallow-pan method. Y Hyphenated. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Peoria: I was about to link this, but is it Arizona or Illinois? The article already says and links Peoria, Illonois. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) On 17 August 2021, Illinois Governor J. B. Pritzker signed a bill designating it as the official State Microbe of Illinois: this is a great fact, but it breaks the chronology: I'd suggest putting it in a footnote, along with the "Mouldy Mary" anecdote. Y Moved to a footnote. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) deep submergence production plant: again, I'd hyphenate deep-submergence, as it's not the production or the plant that were deep. Y Hypenated. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) fourteen 130,000 litres (34,000 US gal) tanks.: I appreciate that this is a consequence of the template, but it's ungrammatical: they were 130,000-litre tanks. This seems to have worked fine in the Australia section below, oddly enough. As before, though, I'd use the imperial measurement first, since that's what they were actually called at the time. Y Corrected. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Did any of the Pfizer scientists, other than Kane, go on to be notable enough for a (red)link? I did check them all, and did not think so. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) This is very much a non-specialist question: given that all strains contain mutations relative to each other, what makes this one a "mutant strain": is that a term that would be used in scholarly sources? Similarly, I think it should be 300 milligrams of penicillin per litre. UndercoverClassicist (talk) 20:23, 9 July 2023 (UTC) These mutant strains were deliberately created by mutating the mould with ultraviolet and X-rays. Hawkeye7 (discuss) 23:38, 10 July 2023 (UTC) The company invested $2.98 million of its own money: sounds a bit like giving them a pat on the back (it wasn't exactly an act of charity): I'd suggest deleting "of its own money". I think it is an important point. It was not an act of charity, but a high risk gamble on an unproven technique. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) I suppose my issue is that "the company invested $2.98 million" has the same meaning, is less verbose and seems less congratulatory to me. I suppose the alternative would be that they borrowed the money, but I'd be surprised if we can categorically rule out that all of this came from their pre-existing funds. UndercoverClassicist (talk) 14:44, 9 July 2023 (UTC) Y Changed as suggested. Hawkeye7 (discuss) 21:39, 11 July 2023 (UTC) Another sixteen plants were built by the private sector for $22.6 million (equivalent to $ million in ), although $14.5 million (equivalent to $ million in ) was approved for accelerated depreciation under which the cost could be written off in five years instead of the usual twelve to fifteen: this could be clearer, particularly as to what is meant by the cost could be written off. In accounting, you write down the cost of an asset over its useful life. Often this is tax-deductable. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Yes; would "for tax purposes" be useful to include at some point? UndercoverClassicist (talk) 14:45, 9 July 2023 (UTC) Another editor will delete it as a tautology. Hawkeye7 (discuss) 23:38, 10 July 2023 (UTC) Not a problem for GA. UndercoverClassicist (talk) 11:01, 12 July 2023 (UTC) Chester Keefer from the MRC was responsible for administering the equitable distribution of penicillin for civilian use.: it sounds like there's a story here: do we know how he made these decisions? A form of triage under which he assessed which patients were most likeley to benefit. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) It's a small thing here, but the current phrasing seems like it's starting in the middle of that story: a little more context would be helpful (a more intuitive phrasing would be something like "[Whatever body/person] placed Chester Keefer, an academic at the Boston University School of Medicine, in charge of establishing a triage system to ensure the equitable distribution of the drug." UndercoverClassicist (talk) 21:35, 10 July 2023 (UTC) Added a bit more about this. Hawkeye7 (discuss) 21:39, 11 July 2023 (UTC) Reads well. UndercoverClassicist (talk) 11:01, 12 July 2023 (UTC) Mass Production Robert D. Coghill: a matter of taste, but just Coghill would be fine here. Equally, if we're going to reintroduce him, remind the reader of who he is. Y Changed as suggested. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Is it semisynthetic or semi-synthetic? The article isn't consistent, and I don't think we ever explained exactly what this word means. Y Linked. Gone with semisynthesic, per our article. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Information about penicillin research in Germany was gathered by the Manhattan Project's Alsos Mission: I'd suggest some context here: what were nuclear scientists doing spying on German mycologists? In particular, I'd clarify what the Alsos Mission was; I initially parsed it as someone's name. Y Although the Alsos Mission was primarily concerned with nuclear technology, it had a broader mission to gather information on German scientific war research. Added in a footnote. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) The section on German-occupied Europe only has a minority of the content from the time of German occupation. Suggest a section on "Continental Europe", into which Germany could be subsectioned if felt necessary. Y Changed as suggested. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) the first traded were seeded on 25 March: I'm not sure what this means. Y Corrected. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) The WPB placed penicillin under allocation: I'm not sure what this means. Y tried to make this clearer. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Chemical analysis Y Changed to "suggested". Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) The chemical structure of penicillin was first proposed by Abraham in 1942.: is proposed here a slightly specialist term: presumably, Abraham made the first formal suggestion as to what penicillin's chemical structure was? We could introduce Hodgkin. Does that sentence really need four citations? Y removed two. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Why is nucleus in (scare) quotes? Y deleted scare quotes. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Methicillin-resistant forms of S. aureus likely already existed at the time: it's probably worth explaining why this was important (I've made a link to MRSA). Y Added. Hawkeye7 (discuss) 21:39, 11 July 2023 (UTC) Patents , The Evening News contrasted its generous support of the Oxford team's work with that of the parsimonious MRC: does its refer to the Evening News or the Rockefeller Foundation? Y Completely obvious, but added the repetition, which makes the article sound poorly written. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) £0.5 million: more usual to say £500,000. Y Changed as suggested. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Nobel prize Who was Rudolph Peters? Added that he was a biochemist but its not really relevant. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Bill Bynum is presented almost as a contemporary observer: was he? Not according to the article. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) an avalanche of nominations: vague and metaphorical: suggest reworking. Y Re-worded. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC)* half to Fleming and one-quarter each to Florey and Chain: do Nobel prizes work like that? I know they can be joint, but didn't know they could be unevenly joint. Yes. It is fairly common. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) When The New York Times announced that "Fleming and Two Co-Workers" had won the prize, Fulton demanded – and received – a correction in an editorial the next day: triple-cited: any need for all three? Yes. One is the secondary source, the other points to the two newspaper articles. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Fleming revelled in the publicity, but Florey did not: suggest rephrasing: it's metaphorical (so not great for readers coming from different backgrounds, contexts, levels of English...) and also unclear: "revelled in" covers a multitude of sins, and "did not" could go anywhere from "didn't throw a party" to "hated it". Y The source says: "Fleming loved the attention and the adulation" (Mason, p. 276) Changed to "enjoyed" send them packing: on a similar note, would rephrase unless a quote. Not changed. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) For the GA review, the article needs to comply with MOS:WTW, which includes MOS:IDIOM. From there: Clichés and idioms are generally to be avoided in favor of direct, literal expressions. Lion's share is often misunderstood; instead use a term such as all, most, two-thirds, or whatever matches the context. … Instead of writing that someone took the plunge, state their action matter-of-factly.. I can't see that either of these are compatible with that instruction, or the rationale behind it of making our language clear and universal. UndercoverClassicist (talk) 21:35, 10 July 2023 (UTC) And I'm not seeing a suggestion of a better, non-idiomatic phrase. Hawkeye7 (discuss) 21:39, 11 July 2023 (UTC) I wasn't prescribing a particular solution, but one needs to be found. You could try "send them away" for "send them packing", "Fleming enjoyed the publicity, but Florey resented it", or any formulation that accurately conveys what the sources say. The important thing is that it meets MOS:WTW, and so the GA criteria. UndercoverClassicist (talk) 21:45, 11 July 2023 (UTC) Y I thought of that but "send them away" is also an idiom. Replaced with a quote from Bickel. "It was a shock to Florey when the news corp arrived at the front door of the Sir William Dunn School. He immediately escaped through the back with instructions to his secretary, Mrs Tuner, to 'send them packing'... a deep abhorrence of the media stayed with Florey for the rest of his life" (Bickel, p. 173) Hawkeye7 (discuss) 22:52, 11 July 2023 (UTC) Yup, making it a quote works well: we can get away with a lot more outside Wikipedia's voice. UndercoverClassicist (talk) 11:01, 12 July 2023 (UTC) Introduce Nanna Svartz No need. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) I disagree: it's always good practice to introduce and contextualise new characters, but in this particular instance, we've explained who Liljestrand was and given a good reason why he would be scrutinising the work, so we ought to treat Svartz in the same way. UndercoverClassicist (talk) 21:35, 10 July 2023 (UTC) Y Added. Hawkeye7 (discuss) 23:38, 10 July 2023 (UTC) Looking at the article on the Karolinska Institute, I now realise that the practice before 1977 was for the Nobel in Medicine to be awarded by the decision of (at least some of) the professors there. Is that worth including? Journalists could hardly be blamed for preferring being fibbed to by Fleming to being fobbed off by Florey,: magnificently British, but I think it needs a total rework for this context: the could hardly be blamed is editorialising. Not editorialising. Not changed. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) In which case, do we have a source that says that the journalists could hardly be blamed? UndercoverClassicist (talk) 14:47, 9 July 2023 (UTC) Yes, in the cited source. Hawkeye7 (discuss) 23:09, 9 July 2023 (UTC) I don't see it, I'm afraid: the source suggests that journalists liked Fleming because he gave them a good story, but I don't see any direct contrast made with Florey or any moral judgement that the journalists should be held blameless (which is itself not a verifiable statement). Remember that we can't take any more than the most trivial inferential steps from the sources without falling foul of Wikipedia's OR standards. UndercoverClassicist (talk) 21:35, 10 July 2023 (UTC) Y Rewritten. Hawkeye7 (discuss) 23:38, 10 July 2023 (UTC) What did Erlanger and Gasser win the Nobel for? For their work on nerve fibres. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Worth a mention, perhaps? Y Not really, but added. Hawkeye7 (discuss) 23:38, 10 July 2023 (UTC) It's a nice reminder that penicillin wasn't the only thing going on in the biological world at the time. UndercoverClassicist (talk) 11:01, 12 July 2023 (UTC) The "In 1943..." paragraph has a massive bundle-cite at the end: it would be clearer to make explicit which sentence comes from which source. Are all five citations really indispensible? Yes. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) There's nothing wrong with it per se, but it's a little odd to so scrupulously maintain WP:TSI throughout the article and then relax that standard for exactly one paragraph. UndercoverClassicist (talk) 21:35, 10 July 2023 (UTC) Y I have moved the refs about to make it clearer what came from where, although they overlap. What puzzles me is nominations for Florey and Fleming in 1946. Maybe they arrived after the closing date in 1945. Hawkeye7 (discuss) 23:38, 10 July 2023 (UTC) Who was Sir Henry Dale? Already introduced above. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC) Ah yes - but we called him Sir Henry Hallett Dale there. Suggest consistency as to what we use as his "full name". Y Changed to "Dale". Hawkeye7 (discuss) 23:38, 10 July 2023 (UTC) Development of penicillin derivatives (bioavailability, spectrum, stability, tolerance): a bit technical, I think, for most readers. Y Deleted. Hawkeye7 (discuss) 20:16, 9 July 2023 (UTC) It was more advantageous than the original penicillin as it offered a broader spectrum of activity against Gram-positive and Gram-negative bacteria: worth reminding the reader that the original penicillin only works on Gram+? Y Added. Hawkeye7 (discuss) 20:16, 9 July 2023 (UTC) The penicillins related β-lactams: this doesn't sound grammatical, though I'm not sure how to fix it. Y re-worded. Hawkeye7 (discuss) 20:16, 9 July 2023 (UTC) Antibiotic preferences differed from country to country: is this strictly past, or does it continue? If the latter, suggest present tense. It was true 15 years ago. Whether it will still be true in ten years' time is likely, but uncertain. Kept the article in the past tense.

  In that case, I'd suggest Chain determined that penicillin was stable only with a pH of between 5 and 8, but the process required a pH below 4. That is ambiguous in this context. UndercoverClassicist (talk)

  N Incorrect. The original is correct, and unambiguous. Hawkeye7 (discuss) 23:09, 9 July 2023 (UTC)

Deep submergence for industrial production

• Anne Sheafe Miller, the wife of Yale University's athletics director, Ogden D. Miller: I'm uncomfortable about glossing women with reference to their husbands: is Ogden Miller really that notable (he doesn't have an article)? If not, I'd suggest cutting that bit: we haven't identified Albert Alexander by who his wife was, or Arthur Jones by his parents.

  Yes, but the athletics director is the most important person at a US university. Today many earn salaries in excess of a million dolars. Miller doesn't have an article but he is notable. [1]. Contempory accounts of course refer to her as "Mrs Ogden Miller", so Anne Sheafe Miller is anachronistic. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC)

  I can't see that her marriage is notable in this context: did her husband or his status play any role in this story? If not, there's enough notability in what happens to her to explain what she's doing in the story, so would strongly counsel deleting. UndercoverClassicist (talk) 20:23, 9 July 2023 (UTC)

  Added an explanation. None of the sources thought it required explanation, so added another source. Hawkeye7 (discuss) 20:49, 12 July 2023 (UTC)

Stopping again for now. My admiration continues: I've made a number of very small copyedits, so it's worth just keeping an eye on typos, punctuation, repeated/redundant words and so on, particularly given how colossal this article is. Its size is outside scope for a GA review: my personal thought would be that it's coherent and so happy enough at this length, but equally there would be nothing wrong with a split if a straightforward and logical line for that exists.

Mass production

• Much of Germany's penicillin came from Czechoslovakia: clarify (if true) that we're talking about the period in which Czechoslovakia was occupied by Germany.
• Work was also conducted in secret in France: which France are we talking about here: that is, on which side of the war?
• The penicillin was called "Hekiso" after its blue colour: non-Japanese-speakers will need this explained.

  It is what the sources say. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC)

  Right, but that doesn't mean that it's understandable or an appropriate phrasing for this website. Do you know (or can you find out) what Hekiso means in Japanese? UndercoverClassicist (talk) 08:22, 10 July 2023 (UTC)

  "Hekiso" is the Japanese word for "penicillin". Hawkeye7 (discuss) 23:38, 10 July 2023 (UTC)

  OK, but presumably it literally means something like "blue mould", otherwise the sentence we've written makes little sense. UndercoverClassicist (talk) 11:01, 12 July 2023 (UTC)

• The UK section reads a little bit like a laundry-list of companies and figures: it would be good to have this hashed out into a more coherent narrative.
• The US production seems to be astronomically higher than that of other countries: the country-by-country approach makes it difficult to see the similarities and differences between them. I'd suggest a short introductory paragraph to the Mass Production section which gives some sort of overall narrative, before we dive into the individual countries.
• Why did so many firms leave the penicillin market after the war?

  The steep drop in price made it hard to compete. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC)

  Worth including in the text, I think. UndercoverClassicist (talk) 21:35, 10 July 2023 (UTC)

  Sure. Provide me with a reliable source and I will add it. Hawkeye7 (discuss) 23:38, 10 July 2023 (UTC)

  I'd assumed that you'd have read it somewhere before writing it here! It's not a major problem: it creates a lacuna in the narrative, but comprehensiveness isn't required for GA. Separately, there's a small problem with only twelve: we haven't actually stipulated how many firms (as opposed to plants: one firm can operate many plants) were manufacturing it before: only is defensible from WP:WTW if it's self-evidently a massive drop, but we haven't shown that. UndercoverClassicist (talk) 11:01, 12 July 2023 (UTC)

  I did read it somewhere, but cannot remember where. The switch to deep submergence was the key; this technique could produce penicillin far more cheaply, but involved a considerable capital outlay. Hawkeye7 (discuss) 20:49, 12 July 2023 (UTC)

Outcome

• This section seems like an oddity: I guess it's trying to explain what penicillin does, but it reads as a too-brief collection of what seems like fairly random information. I'd think about how to integrate that information into the rest of the article and get rid of this section.

Chemical analysis

• I now understand the different designations of penicillin: suggest footnoting and linking the reader down to this section when the first "Penicillin X" crops up. However, it seems from this section that we only found out about these different forms in 1945, which seems to contradict what was earlier stated in the article.
• groups that mask the reactivity of certain functional groups isn't really any clearer than protecting groups to a non-chemist.

  Do you want the explanation deleted? Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC)

  My preference would be to make it clearer, or make it into a footnote, which would give you more space to take the reader through it more slowly. UndercoverClassicist (talk) 14:46, 9 July 2023 (UTC)

  Yes, we did. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC)

  We haven't, however, introduced what a "first generation" is, and so the concept of a penicillinase being "first-generation-resistant" is opaque. It can be guessed at from context, but the writing and explanation could also be far clearer. UndercoverClassicist (talk) 21:35, 10 July 2023 (UTC)

  Minor, but I think the use of all as a noun in arguing that penicillin should benefit all is a little dated these days, and Florey's objection isn't incompatible with there being a patent on penicillin.

  Y added a bit. Hawkeye7 (discuss) 00:30, 9 July 2023 (UTC)

  I'm still not seeing the point, I'm afraid. Was the idea to formalise and standardise what happened when medicines were discovered on the government's time, and what would happen with the resulting commercial opportunities?

  It was to prevent the Americans from patenting the results of British research. The result was a major cultural change away from when scientists made their results freely available. Hawkeye7 (discuss) 23:38, 10 July 2023 (UTC)

  OK, I think I'm beginning to see it here (so the NRDC would go and get the patents itself, making sure that a) they existed and b) the Americans didn't get there first? Would clarify in the text.

Nobel prize

• he feared that this would create a demand for penicillin that he did not yet have to give: clarify this (obviously intended to be "the publicity", but grammatically closer to the fact that Florey disliked that publicity) and the second clause (again, that is awkward because it could, grammatically at least, have either a demand or penicillin as its antecedent).

  Mathematician's answer: of course they can. Methicillin-resistant Staphylococcus aureus emerged long before the introduction of methicillin into clinical practice. MRSA emerged in the mid-1940s. Hawkeye7 (discuss) 21:46, 11 July 2023 (UTC)

  OK, so against the methicillin-resistant Staphylococcus aureus (MRSA) strains that subsequently emerged: the word subsequently [to 1961 at the earliest] needs to be replaced with "had already" or similar. Unless they were effective against pre-1961 MRSA but not post-1961 MRSA? UndercoverClassicist (talk) 11:01, 12 July 2023 (UTC)

Should center be centre per BrE?

Antibiotic resistance

• The widespread belief that antibiotics could cure all ailments: is this backed up by the source? It certainly isn't backed up by the previous sentence: ailments exist which are neither colds nor flu, and I doubt anyone was taking penicillin for a headache or a broken arm.

  It's been done. Hawkeye7 (discuss) 20:49, 12 July 2023 (UTC)

• It reduced the status of doctors to providers of pills: what does this concretely (verifiably) mean?

  In the source. Hawkeye7 (discuss) 23:22, 9 July 2023 (UTC)

  It might be, but the source operates to different rules to this site: we need everything we say to be verifiable, which doesn't just mean that someone has written it somewhere (we can't claim that Carlsberg is probably the best lager in the world, even if we can cite it). We could have something like "it led to patients insisting on being prescribed antibiotics against their doctors' advice", if that's justifiable. Alternatively, it strikes me that this sentence could be removed and the clarity of the paragraph would be improved, quite separately from this issue. UndercoverClassicist (talk) 11:01, 12 July 2023 (UTC)

  Further to this: I don't see that phrase in the source; the closest thing is a complaint from doctors about what they perceived as the decreasing amount of deference paid to them by their patients.

Use in agriculture

• The reasons for this were still subject to debate in the twenty-first century: can we say anything about what has been suggested?

  We could but it wouldn't be very informative. The source says "While debate continues as to the precise mechanisms by which antibiotics and antibacterials promote growth, the U.S. Office of Technology Assessment notes three possible modes of action: a metabolic effect, a nutrient-sparing effect, and a disease-control effect" Followed by a long list of studies.

• When Sweden acceded to the European Union (EU) in 1995, there had been a total ban on antibiotic growth promoters (AGPs) in place there for ten years. This would be superseded by more relaxed EU rules unless Sweden could demonstrate scientific evidence in favour of a ban. Two Swedish and two Danish took up the fight. The odds seemed against them but this coincided with the United Kingdom BSE outbreak, which resulted in intense political pressure. In December 1996, the European Parliament's Standing Committee on Health and Welfare voted to ban the use of AGPs. The EU went further and recommended broad restrictions on the use of antibiotics: I think this bit needs another look: it moves very fast, gives the sense of missing out key details (it mentions that four people were involved, but doesn't identify them), and the language is a little sensationalising at time ("took up the fight", "the odds seemed against them, but..").

Notes and references

• One consequence of the referencing system is that journal citations don't have specific page numbers. There's a way to do this with the {{rp}} template, though I recognise that this would be a lot of work and not strictly needed for GA. UndercoverClassicist (talk) 11:01, 12 July 2023 (UTC)

• What's the system as to whether full citations are used versus SFN?

  Don't understand the question. Hawkeye7 (discuss) 06:16, 10 July 2023 (UTC)

  As I think I understand it, printed books are given as "Smith 2023, p. 1" (SFN), but other types of sources (journals, websites and primary documents) are given in full in the footnote, even when cited multiple times. It's a slightly archaic division nowadays (especially as concerns journals): it makes the "References" section now oddly titled (since it doesn't contain most of the references used in the article) and seems less durable, as it invites some of the typos and other mistakes listed here. UndercoverClassicist (talk) 08:36, 10 July 2023 (UTC)

• Note 23: could I have the direct quote to support As he and Daniel Merlin Pryce, his former research scholar, examined the culture plates, they found one with an open lid and the culture contaminated with a blue-green mould. In the contaminated plate the bacteria around the mould did not grow, while those farther away grew normally, meaning that the mould killed the bacteria?

  It happened that in 1928 I was engaged in a bacteriological research on staphylococci and when for examination purposes I had to remove the covers of my culture plates a mould spore drifted on to a plate. After a time it revealed itself by developing into a colony about half an inch across. It was no new thing for a bacteriologist to find that a mould had grown on a culture plate which had lain on the bench for a week, but the strange thing in this particular case was that the bacterial colonies in the neighbourhood of the mould appeared to be fading away. What had a week before been vigorous staphylococcus colonies were now faint shadows of their former selves. I might have merely discarded the contaminated culture plate as I had done contaminated plates before, but fortunately my previous research work on antiseptics and on naturally occurring antibacterial substances caused me to take special notice of the apparent antibacterial action of the mould.

  Hare began this series of letters by doubting that the translucent colonies observed by Fleming and Pryce were in fact lysed. In his reply, Pryce emphasized that the colonies were both fully grown and lysed, and he suggested to Hare that there was no point in attempting a reconstruction of the famous plate until these facts were taken on board. In a subsequent letter Pryce returned to this point as follows: "Nobody believes that Penicillin lyses staphylococci and I do not for one moment believe that the lysis about the mould was due to Penicillin, but lysis of those colonies there most certainly was. Flem. and I looked at the plate and I thought to myself that the lysis was due to a change of pH, but what I actually said was 'that's how you discovered lysozyme'.

  I'm not seeing anything for meaning that the mould killed the bacteria: the second quote seems to imply that at least Pryce believed that it wasn't the penicillin that killed the bacteria. If these direct quotations are the source, MOS:PRIMARY would prefer a secondary source to confirm them, at least for the interpretation of why what they observed happened.

• Notes 53 and 54: could I have the direct quote(s) here for The Oxford team's first task was to obtain a sample of penicillin mould. This turned out to be easy. Margaret Campbell-Renton, who had worked with Georges Dreyer, Florey's predecessor, revealed that Dreyer had been given a sample of the mould by Fleming in 1930 for his work on bacteriophages, viruses that infect bacteria. Dreyer had lost all interest in penicillin when he discovered that it was not a bacteriophage?

  Hobby:

  Strangely, penicillin had first been produced at the Sir William Dunn School in 1930 - five years before Florey moved to Oxford. George Dreyer, Florey's predecessor, had been interested in bacteriophages - viruses with specific affinity for bacteria that are found in association with essentially all groups of bacteria and blue-green algae. In 1929 he had seen Fleming's paper on penicillin and had obtained a reprint of the article and a culture of the mould. He soon showed that Fleming's Penicillium notatum was not a carrier of bacteriophage, but he continued to grow the mould and use it to obtain plaques of a standard size for quantitation of other bacteriophages. Miss Campbell-Renton, who was associated with Dreyer for many years, had continued this work after his death. Fleming's contaminant thus was cultured in the department at Oxford from 1930 on

  Wilson:

  The Sir William Dunn School of Pathology possessed examples of Fleming's strain of Penicillium notatum. This was a strange coincidence, because Chain certainly discovered Fleming's work by reading the literature and not by any knowledge of previous work at Oxford. But the fact that the mould was in their possession undoubtedly led them to choose penicillin as one of the starting points for their grand survey of microbial antagonism. The mould was in Oxford because Florey's predecessor, George Dreyer, had been working on bacteriophage at the time of Fleming's original observation and had wondered whether penicillin was an example of bacteriophage. Bacteriophage, now known to exist in many different strains and types, is a virus which infects and kills bacteria. As soon as Dreyer found out that penicillin was nothing like a bacteriophage he stopped studying it. There is a story about Chain in his first days at Oxford having bumped into a laboratory assistant carrying a tray of flasks and asking what was in the flasks. When he read Fleming's paper he remembered the incident in the corridor and went to the laboratory of Miss Margaret Campbell-Renton, who had been Dreyer's assistant, and got the mould from her.

  Williams:

  By a strange coincidence this was already available in the laboratory. Dreyer, Florey’s predecessor, had been interested in a class of bacteriolytic agents, known as bacteriophages, discovered by Frederick Twort in 1915. He thought that Fleming’s penicillin might be some kind of bacteriophage and in 1929 had obtained a culture of the mould; this had been maintained at Oxford ever since by Miss Campbell-Renton. According to Heatley, Vollum said that he had ‘played about’ with P. notatum and his culture may have been independently obtained. There was thus no occasion for any direct request to be made to Fleming, who consequently was not aware of renewed interest in his mould.

• Note 61: similar for It was not known why the mould produced penicillin, as the bacteria penicillin kills are no threat to the mould; it was conjectured that it was a byproduct of metabolic processes for other purposes

  Why the mould produces penicillin at all is still obscure: the common pathogenic organisms— so deadly to man— are scarcely a threat to its existence in nature. The supposition is that it is no more than the casual end product of some metabolic process important for other reasons, much as some plants produce highly toxic substances, like strychnine and nicotine, which are not demonstrably useful to them.

  Y That checks nicely.
