From: A role for the ATP-dependent DNA ligase lig E of Neisseria gonorrhoeae in biofilm formation
(A) Biofilm formation in liquid culture by N. gonorrhoeae strains. (B) Proportion of Ngo-Lig E mutants adhering to epithelial cells. (C) Proportion of Ngo-Lig E mutants remaining in the non-adhered (planktonic) state when co-cultured with epithelial cells (D) Proportion of Ngo-Lig E mutants invading epithelial cells relative to the total N. gonorrhoeae (planktonic and adhered). Points are the mean of triplicate measurements and error bars represent the standard error of the mean. Significance values are given as * P ≤ 0.05; ** P ≤ 0.01; *** P ≤ 0.001. Comparisons which showed no significant difference (P > 0.05) are not indicated
