猪源大肠杆菌整合子与耐药性的相关性研究

Investigation of the Relationship between Integrons and Resistance of E. coli from Swine Farms

为分析耐药大肠埃希菌中整合子的流行情况和分子特性,用K-B法分析134株耐药大肠杆菌的药敏情况,并应用PCR方法检测其整合酶基因(intI)和整合子基因盒。结果显示:117株(87.3%)菌株为整合子阳性。表明细菌的多重耐药性与整合子携带高度一致。

In order to analyze the prevalence and molecular characterization of integrons in resistant Escherichia coli isolates. The antibiotic susceptibility of 134 strains of Escherichia coli isolates was tested by K - B methods.The intI and Gene cassettes were examined by PCR. The results showed that 117 （87.3%） strains were positive for integron. These results suggested that there is a good correlation between integron - carrying and the multidrugresistant Escherichia coli isolates.
