摘　　要：目的了解浙江省余姚市水灾后沙门菌在外环境和食源性疾病患者粪便中的分布特征和耐药情况,为食源性疾病防治和临床治疗提供科学依据。方法对浙江省余姚市主城区外环境、食源性疾病患者粪便进行沙门菌增菌、分离培养、生化鉴定、血清分型及药敏试验。结果共检出32种血清型、沙门菌283株,鼠伤寒沙门菌占总数的40.28%。对氨苄西林、哌拉西林耐药率最高,分别为51.59%和42.05%,多重耐药菌36株。结论余姚市沙门菌污染率高、菌型繁多、耐药率高、多重耐药高,优势菌为鼠伤寒沙门菌。水灾后余姚市外环境和食源性疾病患者粪便中沙门菌血清分布和耐药既有相关性又各有特点。Objective To understand the distribution characteristics and drug resistance of Salmonella in water,food and food borne disease patients after flood disaster in Yuyao,Zhejiang province,and provide scientific basis for clinical treatment and prevention of foodborne diseases.Methods Samples were collected from river water in the urban area,food and diarrhea patients in Yuyao,and then enrichment culture,isolation,biochemical identification,serotyping and drug susceptibility test were carried out.Results A total of 283 Salmonella strains were detected in Yuyao during 2014-2016,the detected strains belonged to 32 serotypes,S.Typhimurium was predominant (40.28%).Salmonella had high resistance rate to ampicillin (51.59%)and piperacillin (42.05%).It was found that 36 strains were multi-drug resistant.Conclusion The contamination rate of Salmonella in outside environment was high in Yuyao,the detected Salmonella strains had multiple serotypes,high drug resistance rate and high multidrug resistance.S.Typhimurium was predominant.The distribution and drug resistance of Salmonella in river water,foods and foodborne disease patients after flood disaster had relevance and unique characteristics.
