How worried should we be? Is it killed when the salmon is cooked? What % of salmon have this problem?Andycjp (talk) 02:55, 25 April 2008 (UTC)[reply]

https://www.researchgate.net/figure/A-to-C-Spores-of-H-salminicola-from-a-human-stool-specimen-A-and-from-sockeye-salmon_fig1_13878108 says that they have been found in human stool samples but there's no indication that they are ãlive. If anything, it's a good sign that that's where they're ending up. —Soap— 17:16, 26 April 2022 (UTC)[reply]

MRO

A section describing the mitochondrion related organelles (MROs) should be added. Refs:

Thats a BIG parasite

We currently write:

Individuals are 3-6 mm in diameter

This is an extremely large size for what it is ... an animal that doesnt even breathe ... and much larger than similar parasites such as Myxobolus cerebralis, whose body is no more than six cells during the stage in which it feeds within a fish's tissues. Moreover, because we give the measurement as a diameter, one wonders if the gigantic tail sticking out from the cell body must be correspondingly longer, perhaps almost an inch long.

Is it possible that the "cysts" in the linked paper ([1], which we actually do not link directly) are aggregations of many parasites instead of being the size of one individual?

I looked up more photographs and couldnt find measurements, but the fact that they are microscope slides leads me to doubt that this parasite is actually so big as we say it is. At first, I thought perhaps we had mistaken millimeters for micrometers, but now I thnk it is more likely that we are mistaking a throng of parasites for a single individual. Thoughts? —Soap— 20:45, 12 April 2022 (UTC)[reply]

The other Henneguya species have diameters on the order of a dozen micrometers, as seen at this paper. Thus the description we give overestimates the size of the parasite by a factor of more than a million to one. I wasnot able to find exact measurements with a graph, only charts, but it's still abdundantly clear that the size of the parasite is about 10 micrometers in width, just like the others, and comparable to a human sperm cell maginifed about threefold (not surprising since it is about a dozen cells).

I suspect the fish's immune system is responsible for forming the cysts, because it is hard to believe that something so large could come from something so small, but without finding a paper saying as such I think it is best to just clear up the size different for now.—Soap— 17:16, 26 April 2022 (UTC)[reply]
