Microscopic observation of adherence/invasion of M. genitalium strains to HeLa cells: FITC labeled M. genitalium strains were used to infect HeLa cells with MOI of 1:25 for 1 h as described in material and methods and observed with confocal microscopy. G37, TIM207 and TIM262 indicate infection of cells with M. genitalium wild type G37 strain, MG_207 mutant strain and control strain TIM262, respectively. PBS indicates uninfected control.
