Figure 5From: Microbial inhibition of oral epithelial wound recovery: potential role for quorum sensing molecules? a Wound healing capacity of TR146 cells treated with different concentrations of tilivalline (mean + SD; *p < 0.05). b Wound healing capacity of TR146 cells exposed to K. oxytoca AHC-6 wild type, the ΔnpsB mutant Mut89 unable to produce tilivalline and the Mut89 with npsB complementation (mean + SD; *p < 0.05). c Microbial counts of the different K. oxytoca strains (AHC-6, Mut 89, Mut89 + npsB) present on the insert at time 0 and after 24 h of co-culture with TR146 epithelial cells (mean ± SD).Back to article page
