摘要
目的 了解临床分离的阴沟肠杆菌耐药基因存在状况。方法 对临床分离74株阴沟肠杆菌采用聚合酶链反应检测耐药基因（14种）。结果 74株中TEM、OXA-1 group、DHA、ACT-1、aac（3）-Ⅱ、aac（6’）-Ⅰ、ant（3”）-Ⅰ、qnr、sul Ⅰ、dfrA1和dfrA17阳性率分别为58．1％、2．7％、27．0％、64．9％、16．2％、64．9％、28．4％、4．1％、74-3％、2．7％和27．0％，其余基因均阴性。结论 临床分离的阴沟肠杆菌TEM、ACT-1、aac（6’）-Ⅰ、sul Ⅰ基因携带率高。
Objective To investigate the drug-resistant genes in Enterobacter cloacae. Methods 74 strains of Enterobacter cloacae were isolated from hospitalized patients, and drug-resistant genes were detected by PCR. Results The positive rates ofTEM, OXA-1 group, DHA, ACT-Ⅰ, aac（3）- Ⅱ, aac（6＇）- Ⅰ, ant（3＇）-Ⅰ , qnr, sul Ⅰ, dfrAl and dfrA17 were 58.1%, 2.7%, 27.0%, 64.9%, 16.2%, 64.9%, 28.4%, 4.1%, 74.3%, 2.7% and 27.0%, respectively. The others were not found in all 74 isolates tested. Conclusion There were very high positive percentages of TEM, ACT-l, aac （6＇） - Ⅰ and qacE△l-sul Ⅰ genes in Enterobacter cloacae.
