FIG 4.
(A) Bacterial CFU counts for feces of colonized mice increase more than 5 logs after ampicillin treatment. (B) Time of ampicillin and MAb treatment in colonized mice. (C) Mean bacterial loads in organs postdissemination and in feces on day 8 postcolonization with 108 CFU of K1 K. pneumoniae. Mean log CFU/ml with standard deviations (n = 3 mice per group) are shown. P values were determined by 2-way ANOVA with Dunnett's multiple-comparison test. Asterisks denote comparisons to PBS. *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001. <L.O.D indicates the value is under the limit of detection.
