Fig. 4From: The role of Zur-regulated lipoprotein A in bacterial morphology, antimicrobial susceptibility, and production of outer membrane vesicles in Acinetobacter baumanniiHost cell cytotoxicity induced by A. baumannii OMVs. A549 cells were treated with OMVs from A. baumannii strains for 24 h and then cell viability was determined using the MTT assay. Data are presented as mean ± SD of three independent experiments. + p < 0.01 compared to untreated control cells. ** p < 0.01 comparing the same concentration of OMVs from A. baumannii ATCC 17978Back to article page
