Infection of THP1-derived macrophages.
THP1-derived macrophages were infected with conditional mutant (TB79) and parental strain (TB38) at an MOI of 1:20 in presence or absence of 200 ng/ml of ATc. The growth curve was measured as CFU/ml after release of intracellular bacteria in 100 µl of 0.05% SDS . The values represent the average of two independent experiments with relative standard error.
