FIG. 5.
Total and intracellular bacteria after infection of endocervical epithelial cells with N. gonorrhoeae strain F62 at an MOI of 100:1 (100 gonococci to 1 epithelial cell). The total numbers of viable cells (adherent plus intracellular gonococci) at 1, 2, 4 and 8 h are shown, indicated as CFU/106 endocervical cells (black bars) and intracellular bacteria in epithelial cells at different time points assessed by a gentamicin assay and also expressed as CFU/106 endocervical cells (gray bars). The data are expressed as the mean ± the SD, results representative of three independently performed experiments.
