艰难梭菌是引起人类腹泻的致病菌,艰难梭菌相关性腹泻(CDAD)的发生率在世界各地呈上升趋势。与此同时艰难梭菌在动物粪便及食物中检出率的报道也不断上升,通过食物传播艰难梭菌被认为是引起CDAD的可能途径,但目前尚不清楚艰难梭菌是否为食源性病原体。本文综述了艰难梭菌在水、动物和食物中的检出污染现状及致病菌株的分布。 Clostridium difficile is a causative agent of human diarrhea and the incidence of Clostridium difficile-associated diarrhea (CDAD) is on the rise worldwide. At the same time, the detection rate of Clostridium difficile in animal manure and food has also been on the rise. The transmission of C. difficile through food is considered as a possible pathway of CDAD. However, it is not clear whether C. difficile is a foodborne pathogen . This article reviews the status of detection and detection of C. difficile in water, animals and food and the distribution of pathogenic strains.
