Abstract

ABSTRACT The presence of ampicillin-resistant Escherichia coli (Amp r E. coli ) in the fecal flora of calves was monitored on a monthly basis in seven cohorts of calves. Calves were rapidly colonized by Amp r E. coli , with peak prevalence in cohort calves observed in the 4 months after the calves were born. The prevalence of calves yielding Amp r E. coli in cohorts consistently declined to low levels with increasing age of the calves ( P < 0.001).
