The absence of CXCL2 or CXCL10 did not affect Bacillus internalization by mouse primary neutrophils. Primary neutrophils from C57BL/6J, CXCL2^−/−, and CXCL10^−/− mice were incubated with B. cereus strain ATCC 14579 for 90 minutes. Cells were then treated with gentamicin for 60 minutes to kill external bacteria. Internalization of bacteria by CXCL2^−/− and CXCL10^−/− 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.
