Figure 1. Survival rates (a and c) and ratios of weight change (b and d) in WT, IL-10 KO and TNF-α KO mice following subcutaneous infection with 10⁴ pfu of Oshima and Sofjin strains (n = 12 to 21).

Mice were monitored daily for the averages ratio of weight change of living mice at the time points compared with those of day 0. Error bars represent standard deviations.
