ctp mutation increases OMV-mediated host cell cytotoxicity. The host cell cytotoxicity was measured by treating A549 cells with different concentrations of OMVs isolated from ATCC 17978 and MR14 for 24 h and then performing an MTT assay. Data are presented as mean ± SD of three independent experiments + p < 0.05 compared with untreated control. ** p < 0.01 for comparison of cytotoxicity at the same concentration of OMVs between ATCC 17978 and MR14.
