Colonization capacity of C. jejuni strains in chicks. The influence of flhF on C. jejuni colonization in chicks was evaluated for both the reference strain NCTC 11168 (a) and a C. jejuni isolate (b). The wild-type strain (hollow circle), the flhF mutant strain (hollow triangle) and the flhF complemented strain (cross) are represented by each sample. Five chicks were used in each group, the mean values for each group are depicted by the horizontal bar and asterisks indicate significant differences (P < 0.05 *, and P < 0.01 **)
