From: Haemophilus parasuis VtaA2 is involved in adhesion to extracellular proteins
VtaA2 has no role in the adhesion to lung epithelial cells A549 cells. Adhesion of the clones E. coli BL21 (pLGR-vtaA2) and (pACYC184) to lung epithelial cells A549 after 1 h of incubation (black bars). Concentration of bacteria in the wells at the beginning of the assay are shown in gray bars. Bars represent the mean ± standard deviation of the concentration of bacteria from duplicate wells. Results are representative of 2 independent experiments.
