摘要
目的了解大肠埃希菌(ECO)多药耐药株整合子、转座子遗传标志。方法聚合酶链反应(PCR)检测整合子遗传标志(qacE△1-sul1)、转座子遗传标志(merAt、npA、tnpU)。结果20株ECO中qacE△1-sul1基因阳性14株(阳性率70.0%);merA基因阳性3株(阳性率15.0%)。结论ECO多药耐药株整合子遗传标志(qacE△1-sul1)、转座子遗传标志(merA)携带率高。
OBJECTIVE To investigate the genetic markers of integron and transposon in multidrug-resistant strains of Escherichia coli. METItODS The genetic markers of integron (qacE △1-sul 1) and transpo sons(merA, tnpA and tnp U) were detected by polymerase chain reaction (PCR). RESULTS In 20 strains, 14 strains carried qacE △1-sull , and 3 strains carried merA. CONCLUSIONS There are high percentages of the genetic markers of integron (qac E △1- sull) and transposon (merA) in multidrug- resistant strains of E. colt.
