Disease is called toxoplasmosis, caused by Toxoplasma Gondii, I've heard about it, that's why I've pasted this definition. This AI has blacklist of valid words, toxoplasma is probably on list, toxoplasm is not. I don't know that much about latin, but toxoplasm looks similar to toxoplasma but is something other (sounds like a tissue to me). Toxoplasm without "a" at end probably does not exist, but I may be very wrong, so take that with a grain of salt.
> "protective passage across nerve vessels adjacent to the colon, for example in the trachea"
colon in trachea and toxoplasm(a) forming a protective passage is the funny part for me.
