Abstract:
OBJECTIVE To investigate the resistance gene spectrum and phylogenetic analysis in multidrug-resistant strains of Escherichia coli.METHODS The 34 kinds of resistant genes were detected by polymerase chain reaction and cluster analysis.RESULTS The positive rates of TEM,SHV,CTX-M-1 group,OXA-1 group,aac(3)-Ⅱ,aac(6′)-Ⅰb,ant(3″)-Ⅰ,rmtB,dfrA1,dfrA12,dfrA17,sul1,catB and cmlA were 95%,55%,40%,10%,75%,40%,15%,5%,10%,5%,75%,90%,15% and 35%,respectively.There was clone transmitted phenomenon.CONCLUSIONS There are very high positive percentages of TEM,SHV,CTX-M-1 group,aac(3)-Ⅱ,aac(6′)-Ⅰb,dfrA17,sul1 and cmlA genes in multidrug-resistant strains of E.coli.The multidrug-resistant strains of E.coli can induce clone transmitted hospital infection.
