rAbOmpA attenuates the interaction of A. baumannii with epithelial cells. (A) NCI-H292 cells were pretreated with 10 μg/ml of rAbOmpA for 1 h and then infected with A. baumannii 05KA103 at an MOI of 100 for 1 h. Cell monolayer was stained with the Giemsa solution. (B) NCI-H292 and HEp-2 cells were pretreated with 10 μg/ml of rAbOmpA for 1 h and infected with A. baumannii at an MOI of 100 for 5 h. Invasion efficiency was expressed as the number of bacteria per well using the gentamicin protection assay. The results represent the mean ± standard deviation of three separate experiments. *P < 0.05.
