Aerosol infections with spore mixture. Mice were exposed to a 1:1:1 ratio of spores of the three strains. (A) Four hours after aerosol infection, four mice were sacrificed, NALT and lungs were harvested, and percent CFU of each strain recovered was calculated (green, BAP578; yellow, BAP579); red, BAP580; results shown are mean percentages from NALT and lungs of four mice. (B) The remaining mice were imaged and sacrificed when luminescence was apparent in the area of the cLNs. (C) For mice with more than 1,500 CFU detected in the kidneys, the percent CFU of each strain recovered from the organs was calculated; results shown are from one experiment. ND, no data; NC, not calculated.
