Figure Lengend Snippet: Pulmonary bacterial burden was evaluated in the lungs of bone marrow chimeric mice at 8 (A) and 14 (B) weeks following Mtb infection. NH-TLR2KO, H-TLR2KO, and TLR2KO chimeric mice were compared to WT mice. Time points were performed after separate aerosol infections with 4–5 mice used per group. The number of viable bacteria was determined by plating serial dilutions of lung homogenates onto 7H11 agar plates. Colonies were counted 21 days after incubation at 37°C to determine CFU in the lungs. Data are presented as mean CFU counts ± SEM. Significance was determined by Bonferroni Multiple Comparisons test of One-Way ANOVA. *p<.05; **p<.01 *Denotes significance as compared to WT. Data is representative of two independent experiments with similar results. Expression levels of Ifnγ and Tnf in the lungs of 8 week infected mice (C) were determined by isolation of total lung RNA followed by RT-PCR analysis. PCR data includes 5 mice per group. All data is represented as mean ± SEM. Data is representative of two independent experiments. Significance was determined by unpaired T-test. *p< 0.05.
