FIG. 1.
IL-10−/− mice have increased early resistance to BCG infection. Mice (n = 8 per group) were infected with 107 CFU of BCG. Mice were sacrificed at the times shown on the abscissa, and organ homogenates were plated onto MH9 plates. Colony numbers were counted 25 days later and analyzed by the Mann-Whitney rank sum test. Data are presented as median values with the error bars spanning the 75th to 25th percentiles. NS, not statistically significant. Data are representative of results of three similar experiments.
