Phenotypic response of discordant AcB/BcA recombinant congenic strains. For each strain, a minimum of five mice were tested for C. albicans replication in the kidney 48 h after infection with a low dose of C. albicans. Horizontal bars represent the mean CFU values for each strain. Males and females were analyzed separately. Mean CFU counts for each strain were compared to the contemporaneous A/J (C5-deficient) or B6 (C5-sufficient) control of the corresponding gender. The s.e.m. is indicated for each group and strains that differed significantly from the controls are indicated on the graph (*P<0.05; **P<0.01, ***P<0.001).
