Culturable fecal populations of colonizing C. jejuni strains in C57BL/6 IL-10-/- mice (experiment 2). Levels of growth on TSA-CVA agar medium were scored on a scale of 0 to 4 (0, no colonies; 1, ≤ ~20 colonies; 2, ~20–200 colonies; 3, ≥ ~200 colonies; 4, confluent growth). C. jejuni was not recovered by culture from mice inoculated with tryptose soya broth or with non-colonizing strains 33560 and D0121 at any time. Each point represents an individual mouse.
