Serotyping studies of campylobacter from naturally colonized chickens

Abstract

SUMMARY: Campylobacter jejuni/colistrains from 164 chickens were serotyped by the methods previously described by Penneret al.and Lioret al.The chickens were sampled during breeding from hatching to the age of 42 weeks. The birds were housed, in two separate groups, under different environmental conditions, (for comparison of the effect of hygienic precautions on the transmission of the bacteria during breeding). In the group where the hygienic conditions could be controlled to a greater extent, the chickens became colonized later in the breeding chain and with only one single campylobacter strains.
