How long are cdiff bacterial spores viable outside the body?

Difficult: That is an extremely difficult question to answer. Clostridia are anaerobic, spore-forming rods (bacilli). C. Difficile is the most serious cause of antibiotic-associated diarrhea (aad) and can lead to pseudomembranous colitis, a severe inflammation of the colon, often resulting from eradication of the normal gut flora by antibiotics.

Unknown: Very difficult question. Need to address with a microbiology specialist since this is an anaerobic gram positive bacteria.
