Abstract:
OBJECTIVE To investigate the resistance gene spectrum and their relatedness in Enterobacter cloacae isolated from sputum.METHODS The 15 kinds of resistant genes were detected by polymerase chain reaction and cluster analysis was done.RESULTS The positive rates of TEM,OXA-1 group,DHA,ACT-1,aac(6′)-Ⅰ,ant(3″)-Ⅰ,qnr,dfrA17,sul1 and intⅠ1 were 78.6%,6.3%,18.8%,75.0%,78.6%,56.3%,6.3%,37.5%,87.5% and 87.5%,respectively.Clone transmission was occurred.CONCLUSIONS There are very high positive rates of TEM,DHA,ACT-1,aac(6′)-Ⅰ,ant(3″)-Ⅰ,dfrA17,sul1 and intⅠ1 genes of E.cloacae isolated from sputum.E.cloacae can be clone transmitted in the hospital.
