FIG 4.

Total leukocytes and neutrophils at the site of infection. (a) Total CD45⁺ cells per milligram of tissue of either depilated (Nair)-only, mock-infected (PBS), or infected mice at the indicated time points. (b and c) Neutrophils (Ly6G⁺ CD11b⁺) were determined as the percentage of total CD45⁺ cells (b) or the number of neutrophils per milligram of tissue (c). Each symbol represents the value for one mouse. The bars represent the means with SEM (n = 5 to 15 mice/group). “#” indicates a P value of <0.05 by a Mann-Whitney test relative to PBS.
