2007年重庆市沙门菌监测分析

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。
