Fig. 2From: The Salmonella pathogenicity island 13 contributes to pathogenesis in streptomycin pre-treated mice but not in day-old chickensPilot experiments determined that a dose of 7 log10 CFU resulted in optimal cecal colonization (CFU/g) of S. Enteritidis in a streptomycin pre-treated mouse model. C57BL/6 mice were infected with 7 log10 CFU of the WT KanR or UK KanR WT strains. Bars represent mean ± SEM of three mice for each time point except for day 7 p.i. where only two mice were sacrificed in the UK KanR infected group. Significant differences were determined with two-sample t test not assuming equal variances (*P < 0.05)Back to article page
