FIG. 3.

T. cruzi-infected IL-10^−/− mice develop a profound body weight loss and hypothermia. Groups of five mice were infected with 50 trypomastigotes of the Tulahuen strain, and their body weights and rectal body temperatures were measured in IL-10^−/− mice (open symbols) or heterozygous-littermate controls (solid symbols). The results are presented as the mean of individually analyzed mice, including the standard deviation. The means and standard deviations of one representative of two independent experiments are shown.
