Survival of B. bronchiseptica (RB50), B. parapertussis (CN2591), and B. pertussis (Bp 536) wild-type strains and the B. bronchiseptica and B. parapertussis Δwbm mutants (RB50 Δwbm and CN2591 Δwbm, respectively) in naive-rabbit serum. Bacteria were grown to mid-log phase (optical density at 600 nm, ≤0.3) in Stainer-Scholte broth and diluted in PBS. A total of 500 CFU of bacteria were incubated at 37°C for 1 h in 50 μl of 90% naive-rabbit serum. Serum resistance is presented as percent survival relative to that of a PBS control with standard-error bars (n = 3).
