FIGURE 1.

Six-to-eight-week-old wild-type C57BL/6 mice infected with TC-83 or mock infected with PBS were monitored throughout the course of study. Symptomatic (S, N = 3) animals developed weight loss consistent with infection around D5 and did not begin regaining weight until D11. Asymptomatic (A, N = 7) and mock (M, N = 4) animals did not develop weight loss or show other signs of infection. S animals did not reach weights comparable to the A or M animals until D20. Weights are expressed with grams with the SD for each group. Asterisks indicate significantly lower weights (p < 0.05) in the symptomatic groups when compared to both asymptomatic and mock groups. When compared using a One-Way ANOVA, weights were not significantly different between mock or asymptomatic groups post-infection.
