FIG. 6.
Colonization of chicken ceca by wild-type C. jejuni NCTC 11168 (circles) and its fucP mutant (squares) in mono- and coinoculated groups. In two separate experiments, young chicks were inoculated with a high dose (108 CFU per chicken) (A) or a low dose (105 CFU per chicken) (B). In each experiment, birds were inoculated with either a single strain (open symbols) or a 1:1 mixture of the wild type and the mutant (filled symbols) and sacrificed after 5, 10, or 20 days postinoculation (DPI). Each point represents data from a single bird. A horizontal bar indicates the mean for each group. P values above paired groups reflect significance as determined by a two-sample t test.
