Genetic Markers of Integron and Transposon in Multidrug-resistant Strains of Escherichia coli / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the genetic markers of integron and transposon in multidrug-resistant strains of Escherichia coli.METHODS The genetic markers of integron(qacE△1-sul1) and transposons(merA,tnpA and tnpU) were detected by polymerase chain reaction(PCR).RESULTS In 20 strains,14 strains carried qacE△1-sul1,and 3 strains carried merA.CONCLUSIONS There are high percentages of the genetic markers of integron(qacE△1-sul1) and transposon(merA) in multidrug-resistant strains of E.coli.
