Colonization of Broilers with Campylobacter in Conventional Broiler-Chicken Flocks

Abstract

Eight of 16 conventional broiler-chicken flocks examined contained Campylobacter. All isolates were identified as C. jejuni except from 1 flock were C. coli was isolated. One herd consisting of 6 different houses where Campylobacter regularly has been isolated was continuously examined. It was not possible to isolate Campylobacter from newly hatched chickens or from environmental samples and cloacal swabs during the 2 first weeks of growth.
