S. aureus internalization into MAC-T cells measured as CFU remaining after 2 h (A) or 24 h (B) of incubation after killing of extracellular bacteria. Each bar represents the number of intracellular CFU per milliliter from 11 to 24 wells (A) or 17 to 24 wells (B) run in separate experiments. Values a and c represent P values for comparisons with S. aureus RN6390, whereas values b and d are for comparisons with strain Reynolds (CP). SEM, standard error of the mean.
