C Diff is pretty distinctive once you have it...there is a putrid odor, lots of mucous, D, often times bloody. Lots of cramping, sometimes accompanied with fever, and general a feelng of just not feeling well. Usually flagyl and cipro are the first antibiotics. If those don't work, then vancomycin is the next course, and then difficid. Ufortunately, I have had it five times and hospitalized with it four times.
