Summary of age-dependent differences between C. jejuni-colonized broiler chickens and non-infected controls. Time dependent reductions in the mean weights of Campylobacter-infected chickens are indicated. Relative increases in the cecal cytokine/chemokine expression of C. jejuni-colonized birds compared to age-matched non-colonized control birds are marked by up arrows (↑), and down arrows indicate decreases in cytokine/chemokine expression (↓). Representative members of the cecal microbiota showing greater differential abundances between age-matched C. jejuni-colonized birds (↑) and non-colonized controls (↓) are indicated by their consensus genera and corresponding abundance rank identifying OTU numbers. NS indicates no significant differences between Campylobacter-colonized birds and non-infected controls
