Invasiveness assays of bacteria into Caco-2 human epithelial cells.

<p>Caco-2 cells were co-incubated with LL-wt, LL-BLG, LL-FnBPA+ BLG and LL-FnBPA+ during 1 hour and then treated with gentamicin for 2 hours. Cells were lysed and the number of CFU internalized was measured by plating. *, survival rates were significantly different of LL-wt and LL-BLG (One-way ANOVA, Bonferroni's multiple comparison test, p<0.05). The results presented are from one experiment representative of three performed independently.
