FIG. 2.
Co-colonization by wild-type K. pneumoniae LM21 (■) and its capsule-defective mutant, K. pneumoniae LM21(cps) (▴), of the intestines of streptomycin-treated mice. (A) The strains were fed simultaneously at 108 CFU to streptomycin-treated mice. (B) The strains were fed simultaneously at 105 CFU to streptomycin-treated mice. Symbols for day 0 represent the sizes of the inocula. At the indicated times, fecal samples were plated as described in the text. Bars represent standard errors of the means.
