Fig. 5From: Post-weaning diarrhea in pigs weaned without medicinal zinc: risk factors, pathogen dynamics, and association to growth rateThe cumulative incidence of enterotoxigenic E. coli shedding after insertion into the nursery unit. The cumulative incidence (Kaplan–Meier failure estimates) of fecal shedding of enterotoxigenic E. coli (ETEC) as a function of time since insertion in the nursery unit (days) at two Danish indoor productions (A, B). The pigs were systematically sampled every second day. Failure was defined as: Rectal swabs cultured on blood agar displayed overgrowth of hemolytic colonies confirmed to be ETEC by PCRBack to article page
