Genetic Marker Study of Plasmid,Transposon and Integron in Multidrug-resistant Acinetobacter baumannii in Xinjiang / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To know genetic marker existence condition of plasmid,transposon and integron in multidrug-resistant Acinetobacter baumannii in Xinjiang.METHODS The plasmid(traA,traF),transposon(tnpA,tnpU,merA) and integron(intⅠ1) in MDR-ABA 20 strains were studied.RESULTS From them 5 strains(25%) were tnpU positiye,4 strains(20%) were intⅠ1 positive,4 strains were tnpU and intⅠ1 simultaneously positive,and others were negative.CONCLUSIONS IntegronⅠexists extensively in A.baumannii in Xinjiang.Their multidrug resistance is correlated with transposon and integron carried by ABA.
