国内旅游者腹泻病原学及感染因素研究

Etiological and Infectious Factors of Dysentery among Domestic Tourists

摘要: １９８８～１９９８年７～８月的旅游季节，我们对来自全国１８个省、市、自治区２３７例旅游腹泻患者进行病原学及感染因素调查，共检出致泻菌１４种１１８株，检出率为４９.７９％，以致病性弧菌、致泻性大肠杆菌及变形杆菌为主。分别占５２.５４％（６２／１１８）、１６.９５％（２０／１１８）和１３.５６％（１６／１１８）。感染因素主要有食用不洁饮食，海产品加热不透及游泳时不注意，被污染的海水呛入胃内感染而发生腹泻。建议加强旅游环境治理和提高自我保护意识。
