No wonder they have such a small sample. After the informed consent form I'm sure lots of people told the researchers to gtfo.
If you had C. diff, you'd be doing everything including licking doorknobs at a urgent care clinic to try to get some healthy gut bacteria back.
I'm guessing they had people lined up and turned away for the study. Except they'd have to have their friends line up, because if you have C. diff, you can't wait in a line. For anything. Including the toilet.
Also, could an MD please provide the usual time frame in which diarrhea runs its course? 8 weeks being an improvement sounds just weird.
C. diff doesn't go away by itself. Antibiotics, if they work, work by killing everything off in your gut (again - because lots of times, you're going to have to do multiple rounds of ABs), then just hoping that other bacteria get back in there before the C. diff re-establishes itself. Else repeat, until the subject dies.
IAAD, BNTKOD*, but for some reason I know way more about this than I ever wanted to.
