seagull  I choose sterilization because C-diff is essentially an imbalance of colonic flora due to antibiotic "sterilization" leading to expansion of C. Diff. However, I ca see how toxin- mediated is the true mechanism but the question seems dirty to me. +7  
jd1  I think also technically sterilization refers to inactivating spores (as opposed to disinfection which would not), so would imply Cdiff would be killed off too +6

I also first chose sterilization but later move it to toxin. Its very straight if u look at it that toxin is the one causing diarrhea. Sterilizing gut flora occrs everytime u take antibiotics, its predisposing to C. DIff but not actually causing diarrhea otherwise everyone would get it.
