FIG. 5.

Tempo of pulmonary inflammation. BAL fluid and lung cells were harvested on day 5, day 7, and day 9 after MHV-1 infection for each of the indicated mouse strains. Total mononuclear cells in the BAL fluid (A) and lung (B) were counted using a hemocytometer. The results are expressed as the mean of four mice per group. The error bars indicate the standard deviations. The experiment was performed twice with similar results. *, P < 0.05 for day 9 C3H/HeJ mice versus day 9 A/J, day 9 BALB/c, and day 9 C57BL/6 mice as determined by ANOVA.
