In this study, we compared two types of chicken infection models for Campylobacter jejuni in terms of infectious dose required to colonize the chickens and the susceptibility of chickens of different ages to persistent colonization by C. jejuni. In one model, chickens at day 2 posthatching were used, and in the other, 14-day-old chickens were used. The minimum C. jejuni cell number required to colonize 14-day-old chickens was 5 x 10⁴ cells, and that for 2-day-old chickens was 5 x 10³. The ability of various C. jejuni strains to colonize the chicken gastrointestinal tract was the same in both models.
