FIG. 4.

The role of MyD88 in S. aureus (Staph)-induced corneal inflammation. Corneas of control and MyD88^−/− mice were treated as described in the legend for Fig. 2 and exposed to heat-inactivated S. aureus Wood strain. Neutrophils, corneal thickness, and haze were measured as described in the text. Data are the means ± SEM (error bars) of five mice per group. The P value was <0.05 for C57BL/6 versus MyD88^−/− mice. Similar results were found in repeat experiments.
