DETECTION OF PLASMID-MEDIATED QUINOLONE RESISTANCE GENES IN AVIAN ESCHERICHIACOLI ISOLATES FROM SHANDONG PROVINCE IN 2012-2013
摘要
Abstract
To investigate the distribution of plasmid-mediated quinolone resistance (PMQR) genes and their effect on the bacterial resistance to the quinolone antibiotics in recent years, qnrA, qnrB, qnrC, qnrD, qnrS, oqxA, oqxB and qepA genes of 93 avian E. coli strains isolated from Shandong Province were detected individually in PCR, and the resistance to Quinolones (Ciprofloxacin, Lomefloxacin, Ofloxacin, Norfloxacin, Pefloxacin) was detected in antimicrobial susceptibility test. Among 93 E.coli isolates tested, 47 (50.54%) to 80 (86.30%) strains were resistant to five Quinolones respectively, and 56 (60.21%) strains were positive to PMQR genes. In addition, 25 isolates (26.88%) harbored two kinds of PMQR genes and 1 isolates (1.07%) harbored three kinds of PMQR genes. The positive rates of qnrS, oqxA and oqxB gene were 22.58%(21/93), 40.86%(38/93) and 24.73%(23/93) , respectively. None of qnrA, qnrB, qnrC, qnrD and qepAgenes was detected.关键词
