Survival of BCG in in vitro granulomas of healthy individuals. All samples were separated through density dependent centrifugation from peripheral blood of volunteers and PBMCs were isolated after washes with PBS. In each category 6 × 104 bacteria and 6 × 105 immune cells were used for an MOI of 0.1:1. CFU counts of granulomas formed from healthy individuals’ PBMCs showed a decrease at 15 days when treated with L-GSH. Data represent means ± SE from eight healthy individuals. * p < 0.05 when comparing L-GSH treated samples to untreated samples at 15 days.
