I have a ton of information on this stuff because of my work I should post some pics. and other info; might help you guys out.
Just so you guys know doing a fecal float on PDF crap won’t work to well, instead do smears, this will give you a better sample to look at. You would only do a float if you had something like a teaspoons worth of crap. With a smear all you need is a very small amount. I have done both methods with great results, but I think the smear works out a little better.
Hope this helps.
