Relative expressions of adeB, adeJ and adeG in CSAB and CnSAB strains. The RND family efflux pump expression was determined by the quantitative real-time PCR, and Acinetobacter baumannii strain ATCC 17,978 was taken as a reference. All reactions were carried out in triplicate. The black dot indicates carbapenem susceptible Acinetobacter baumannii (CSAB) strains; the Black square denotes carbapenem non-susceptible Acinetobacter baumannii (CnSAB) strains. S, significant; NS, not significant
