Figure 6

Adherence (A) and invasion (B) of H. parasuis wild-type SC096, ΔlgtB and Δlex-1 mutants and complemented strains in PK-15 cells. The data represented the number of bacteria that adhered to or invaded the cells in each well of a 24-well plate. Error bars represent the standard deviation from three independent experiments performed in triplicate. The asterisks indicate that the number of bacteria bound to the PK-15 cells was statistically different (p < 0.01) from that of the wild-type SC096 strain as judged by the Student t-test.
