The ΔltaS mutant is not impaired in its capacity to resist blood bactericidal killing. Capacity of the S. suis wild-type strain P1/7 (black), ΔltaS (blue) and ΔcpsF (grey) mutant strains to resist the bactericidal effect of murine whole blood after 2 h of incubation. Percentage of bacterial survival was calculated in comparison to bacteria in plasma alone. Data represent the mean + SEM (n = 3 independent experiments). * (p < 0.05) indicates a significant difference between the wild-type and mutant strains.
