Fig. 6

C57BL/6 mice infected with the WT M. tuberculosis parent strain (ML2710), the Δrv0455c mutant (ML2711), and the complemented strain (ML2701). Colony-forming unit (CFU) counts in the lungs (a) and spleens (b) of mice infected with the indicated strains. Data represent the mean ± s.d. of four mice per time point. Note that one mouse infected with Δrv0455c mutant was euthanized on day 51 due to an unrelated illness. Source data are provided in the Source Data file. c Gross pathology scans of left lung lobes of mice harvested on day 70 after infection. d Histopathology of lungs of mice harvested on day 70 after infection. The scale bar is 1 mm. Data were obtained from two independent experiments and representative images are shown.
