Measurement of the viability of
in macrophages after co-culture with PBMCs. At day 9 after culture of macrophages infected M. leprae with or without PBMCs, macrophages were lysed, and the viability of M. leprae was determined by a radiorespirometric assay. Unpaired Student’s t test was used to determine the statistical significance of the two data sets. Representative data of three individual experiments are shown.
