2007年重庆市沙门菌监测分析

Surveillance and analysis of <I>Salmonella</I> in Chongqing,2007

  • 摘要: 目的掌握沙门菌在腹泻病例中的感染率、沙门菌菌型种类及分布特征、药物耐药特征。方法确定监测病例定义及监测点,监测就诊和腹泻病暴发疫情中腹泻病例的沙门菌血清型别,并进行PFGE和耐药实验。结果2007年重庆市腹泻病例中沙门菌的感染率为8.74%,发现10个血清型的沙门菌,主要以汤普逊和鼠伤寒为主,秋季是发病高峰。沙门菌导致了10起腹泻病暴发,发生地点主要在居民家中或社区聚餐,鼠伤寒沙门菌是主要的致病菌,皮蛋是主要的危险食物。5种血清型的87株沙门菌做PFGE分析,鼠伤寒与汤卜逊沙门菌分别有3个基因型,婴儿、B群只有1种基因型。10个血清型的沙门菌分别对7种抗菌素出现耐药。结论沙门菌是导致腹泻疫情的主要致病菌之一,加强皮蛋的监测是降低发病的重要干预措施之一。

     

    Abstract: ObjectiveTo determine the infection rate, bacterial type, distribution and drug resistance associated with ISalmonella/I among diarrheal cases. MethodsCriterion of target cases and surveillance sites having been established, ISalmonella/I serotypes of diarrheal cases during outbreaks and those visiting the surveillance clinics were identified, and PFGE and drug resistance test conducted. ResultsThe infection rate of ISalmonella/I among diarrheal cases in Chongqing in 2007 8.74%. Ten ISalmonella/I serotypes were detected, mainly ISalmonella/I thompson and typhimurium. Peaks were seen in autumn. ISalmonella/I had led to ten outbreaks of diarrhea, occurring mostly in home or at community dinner parties, in which ISalmonella/I typhimurium constituted a major pathogen. Preserved eggs were the major risk. PFGE analysis of the 87 strains, 5 serotypes of ISalmonella/I revealed 3 genotypes of ISalmonella/I typhimurium and thompson but only one genotype in group B among affected babies. Drug resistance was shown in 10 ISalmonella/I serotypes against seven kinds of antibiotics. ConclusionISalmonella/I was one of the major pathogens leading to diarrhea epidemics. Strengthening the surveillance of preserved eggs was an important intervention to reduce the incidence.
