I have read a little already about doing fecal testing, so I think I have a general understanding. But, I have read about some other diseases. I think they are CAE, cocci something, and John. I would like to know how they are tested for and what they are. I am having trouble searching for what I would like to learn because I am not sure what the right names are. I would like to read up on these things so I can know why to do the test and how to do them or who I should have do them for me. Thank you.
