Abstract

We have studied colonization of crops in newly hatched leghorn chicks (a layer breed) by wild-type and mutant strains of Campylobacter jejuni. We established that the wild-type parent strain forms a stable population level within the crop and that the mutant strains will do likewise. Concentrations of mutant strains in the crop were usually below that of the wild-type parent strain and ranged from 103 to 105 colony-forming units. These results differ from results we have previously reported concerning cecal colonization, where these same mutant strains lacked colonizing ability. The present results, therefore, indicate that bacterial factors necessary for colonization of the crop are not the same as those needed for colonization of the cecum.
