Figure 2. Microscopic observation of cytotoxic effect of M. genitalium strains on cervical epithelial cells.

Figure 2

HeLa and C33A epithelial cells were infected with M. genitalium G37 and MS5 strains and analyzed using differential interference contrast at 488 nm in a confocal laser scanning microscope with 20× objective. PBS indicates uninfected control cells; G37, MGRE, MS5 and HKG37 indicate infection of cells with M. genitalium wild type G37 strain, control strain MGRE, msrA mutant strain MS5 and heat killed G37 bacteria, respectively.
