My dad went to the dr. today after having bad diarrhea of & on for a couple of months. The dr. thought it might be something he caught while in the hospital a while before Christmas. He has to collect stool samples. One needs to be frozen & the other is just a regular one. The dr. didn t want to start the antibiotics until he knew if it was this particular thing. My sister took him, & I thought she was saying it might be C-bis. However, I don t think I understood her. I don t find that on your web site or on the internet. Could you tell me what it might have been? Thanks for your time.
