Fig 5. Spores of the csB mutant show increased adherence to cervical but not vaginal cells compared to wild-type spores.

Cervical cell lines Ect1/E6E7 (A) and End1/E6E7 (B) and vaginal cell line Vk2/E6E7 (C) were incubated with spores for 3 hours, washed to remove unbound spores and the number of bound spores determined. The results represent the average of four independent experiments and error bars represent standard error of the mean. Asterisks indicate statistical difference at p ≤ 0.05. Wild-type, WT; csA mutant, csA-M; csB mutant, csB-M; csB mutant complemented, csB-C.
