摘　　要：[目的]分析闽江流域不同断面大肠杆菌(Escherichia coli)SepA基因序列,并对其抗生素耐药性进行比较。[方法]对分离自福建闽江流域不同断面的大肠杆菌的SepA基因进行测序比对,并对该菌株进行耐药性分析。[结果]不同断面分离的大肠杆菌SepA基因序列和抗生素的耐药性均存在一定的差异。[结论]该研究可为今后进行闽江流域污染源的追踪、风险评估和开发特异性探针提供依据。[Objective] The research aimed to analyze the SepA gene sequence in E.coli from the surface watershed of Minjiang River,and compare its antibiotic resistance.[Method] The SepA gene sequence and antibiotic resistance in E.coli from the surface watershed of Minjiang River were compared.[Result] The results were discovered that SepA gene sequence and antibiotic resistance had certain difference.[Conclusion] The study can provide basis for tracing the main pollutive source,risk identification,screening of species-specific DNA probes in Minjiang River.
