How long does it take to contract c. Diff. After coming in contact with infection?

CDI sooner or later. We're constantly in contact w/bacteria like c. Diff. We 'eat' the spore or rarely the vegitative (actively growing) bacteria. Stomach acid kills veg form. The spore passes to bowel & hangs out (>1 mo). It can pass out or if conditions are right (normal flora disrupted) due to antibiotics, immunedefic, chronic illnesses, chemo, or bad luck it sprouts to veg form & makes toxins which make us ill.
