OBJECTIVE To investigate the correlation between the acquired resistance-related genes and the markers of mobile genetic elements in multidrug-resistant Klebsiella.METHODS The acquired resistance genes toβ-lactams,aminoglycosides,quinolones,rifampicin,disinfectants and genetic markers of mobile genetic elements including conjugal plasmids,transposons,insertion sequences,and integrons in 20 strains of multidrug-resistant Klebsiella were detected by polymerase-chain-reaction(PCR)then the index cluster analysi...
