Expert verification

[edit]

Hi. I'm an expert, and I verify this article. 67.249.232.42 (talk) 23:36, 31 July 2010 (UTC)[reply]

Kindly include and elaborate about Plant pathogens

[edit]

Plant pathogens are necessarily biohazards. They include a versatile kind of slime-moulds, fungi, bacteria, viruses, viroids. They are hazardous because

  • Plant pathogens can spread and destroy food crop plants and agricultural fields. (See also: Famine )
  • or can destroy or even wipe-out vegetation and biodiversity (See also : Forest_dieback)
  • or can deteriorate stored food grains/cereals, vegetables, etc. that makes the food inedible or toxic and/or distasteful. That can cause financial loss as well as hunger. (See also: Food spoilage , Post-harvest_losses_(vegetables))
  • Some plant pathogens and even plant beneficial microbes (some benificial endophytes that promote the plant to grow, without no appearent visible lesion) infect the live plant can make the plant toxic to human and cattle, such as some ergots.
  • Some plant pathogens can cross infect human or cattle, and can be deadly. such as Aspergillus spores.
  • Some plant pathogen spores can survive for prolonged period, so after a prolonged period of unfavourable condition to the micobe when the optimal environmental coditions match the plant pathogens can multiply exponentially and can cause plant disease or famine.
  • Some bacteria such as some rhizobacteria are able to transfer DNA into plants, which get integrated into host plant's DNA.

So I request to elaborate on plant pathogens as biohazards, and their safe handling methods and regulations.

Removed misinformation about COVID-19

[edit]

As of 17:56, 14 April 2020, Pbsouthwood added COVID-19 to the list of "Bacteria and viruses that can cause severe to fatal disease in humans, but for which vaccines or other treatments exist" in §Levels of biohazard. This was not supported by the cited CDC reference: Coronavirus Disease 2019 (COVID-19) > Lab Biosafety Guidelines,Updated March 31, 2020.

I removed the mention and reference.

Symbol graphic with dimensions

[edit]

I've moved the orange symbol graphic with dimensions from the lede paragraph, where it is redundant with the main graphic and its level of detail is excessive, to the Symbol section.

SARS-COV-2 and caption: BRD

[edit]
SARS-CoV-2 usually causes mild illness in humans, but is capable of causing severe illness that can result in death, particularly among the elderly, pregnant women and those with a weakened immune system or certain medical conditions.

With this diff, Captain Cornwall made a bold edit by adding the image and caption at the right. The caption not an accurate summary of the SARS-COV-2 and COVID-19 articles, and frankly reads to me as wp:advocacy for the view that the efffect of COVID-19 is overstated for the large majority of people. The image has the additional problem that an isolated virus does not come with a biohazard warning, such as might be found on bags of clinical waste: it really is not a relevant image for this article.

Rather than revert it straight away per wp:Bold, Revert, Discuss, I tried to tone down the POV-pushing caption to read "SARS-CoV-2, the cause of COVID-19". The wp:Short description at SARS-Cov-2 reads "Virus strain that causes coronavirus disease 2019 (COVID-19)"

Captain Cornwall reverted this compromise, saying that [this short description] "is debatable", insisting on their version. Consequently I am now reverting the original change per WP:BRD and WP:STATUSQUO. An argument must be made (a) whether or not this image is useful in this article, recalling that "images are to inform, not to decorate" and (b) [if it is] what caption is appropriate, recalling WP:FORK. --John Maynard Friedman (talk) 15:02, 14 October 2020 (UTC)[reply]
