Beige mice were infected with M. avium 2-151 smt by
aerosol route four weeks post final immunization. (A-C) Bacterial
burden was assessed by colony forming unit (CFU) in lung (A), spleen (B), and
liver (C) organ homogenates six weeks post challenge. CFU means were compared
between each group using one-way ANOVA with Dunnett’s multiple
comparisons test. Black line and error bars show mean ± SEM, dots
represent individual mice, n = 6–7/group. Asterisks indicate statistical
significance, where *p < 0.05, **p < 0.01, ***p < 0.001 and
****p < 0.0001.
