Fig 6. Released METs have no bactericidal effects on M. mass R.

Fig 6

To determine the bactericidal effect of METs on M. mass R, macrophages with METs-degrading DNase I 30 min before infection. (A) Cell-associated (intracellular or METs-bound), (B) Extracellular, (C) Total number of bacteria recovered from the samples infected by M. mass R (MOI 5) for 24 hr, with or without DNase (50 units/ml). (D) AFB staining of THP-1 macrophages infected by M. mass R with or without DNase for 24 hr. Bar, 20μm. Data are representative of three independent experiments with similar results. **, p<0.01 by Student’s t-test.
