Primary neutrophils from C57BL/6J, CCL2−/−, and CCL3−/− mice were incubated with B. cereus strain ATCC 14579 for 90 minutes. Cells were then treated with gentamicin (Gen) for 60 minutes to kill external bacteria. Internalization of bacteria by CCL2−/−, and CCL3−/− neutrophils was not significantly different from that of C57BL/6J neutrophils. C57, C57BL/6J; Gen+, Gentamicin treated; Gen-, Gentamicin untreated. Values represent mean ± SEM of N ≥ 5 for at least two separate experiments; *P < 0.05. Dashed lines represent the initial bacterial inoculum. nsP≥0.05.
