FIG 8.

PMN infiltration in TLR4^−/− eyes infected with B. cereus. C57BL/6J and TLR4^−/− mouse eyes were infected with 100 CFU B. cereus. PMN infiltration was quantified by quantifying the MPO concentrations in infected C57BL/6J and TLR4^−/− eyes by an ELISA. MPO concentrations at 8 and 12 h postinfection were significantly higher in infected C57BL/6J eyes than in infected TLR4^−/− eyes (P ≤ 0.016). Values represent means ± SEM for ≥5 eyes per time point with at least three independent experiments. *, P ≤ 0.016.
