摘要: 韦太夫雷登沙门菌源于印度, 是典型的人畜共患病, 依靠特殊共生能力成为南亚和东南亚区域腹泻患者、水禽、海鲜中首位非伤寒沙门菌, 以人流(旅游)、物流(食品贸易)和洋流(海鲜)持续扩散至其他国家, 目前已定殖于国内养殖海水贝壳类和禽类中, 流行于华南地区:首次在国内规模化养殖鸡场发现韦太夫雷登多重耐药的优势克隆(MDR-ACSSuT), 而人源的耐药株罕见;首次在国内发现部分血液感染病例的暴发。韦太夫雷登已融入中国的养殖贝壳和禽类产品的产业链和食物链中, 具有全球生态扩展能力。中国近来的暴发有增多趋势, 发达国家在预防和处置食源性病原的污染、输入和暴发调查的制度和经验值得借鉴。Abstract: Salmonella enterica serovar Weltevreden is originated from India and has become the most common non-typhoid Salmonella in south and southeast Asia due to its special commensalism ability, which can cause zoonosis worldwide through population floating, consumption of contaminated food and seafood. In China, S. Weltevreden circulates in the southern area. A multi-drug resistant clone (MDR-ACSSuT) was detected in a chicken farm for the first time, while human strains are mostly quite sensitive to antibiotics currently. Moreover, blood infections were detected for the first time too. S. Weltevreden has colonized in shellfish and poultry breeding and raising chain and food chain, and more outbreaks of S. Weltevreden infection have been reported. It is necessary to learn about the practices in preventing and control foodborne infection, case importation and the mechanism of outbreak survey of S. Weltevreden in developed countries.
