在位于南美洲北部海岸的法国海外领土法属圭亚那，从人类感染中分离出的沙门氏菌血清型中有近50%属于在法国大城市很少遇到的血清型。已经调查了一种爬虫类的污染源。2011年4月至6月期间，在卡延附近地区收集了151种爬行动物：38种蜥蜴，37种蛇，32种海龟，23种绿鬣蜥和21种凯门鳄。收集并培养泄殖腔拭子样本。分离的沙门氏菌进行了生化鉴定和血清分型。总携带频率为23.2%(95%可信区间为16.7 ~ 30.4)，血清型菌株23株。野生爬行动物携带沙门氏菌的频率显著高于野生爬行动物。从爬行动物中分离出的近三分之二的沙门氏菌血清型也从法属圭亚那的病人中分离出来。我们的研究结果强调了与处理和食用爬行动物有关的风险，以及它们在环境中沙门氏菌传播中的作用。(C) 2014 Elsevier B.V.版权所有
In French Guiana, a French overseas territory located in the South American northern coast, nearly 50% of Salmonella serotypes isolated from human infections belong to serotypes rarely encountered in metropolitan France. A reptilian source of contamination has been investigated. Between April and June 2011, in the area around Cayenne, 151 reptiles were collected: 38 lizards, 37 snakes, 32 turtles, 23 green iguanas and 21 caimans. Cloacal swab samples were collected and cultured. Isolated Salmonella strains were identified biochemically and serotyped. The overall carriage frequency of carriage was 23.2% (95% confidence interval: 16.7-30.4) with 23 serotyped strains. The frequency of Salmonella carriage was significantly higher for wild reptiles. Near two-thirds of the Salmonella serotypes isolated from reptiles were also isolated from patients in French Guiana. Our results highlight the risk associated with the handling and consumption of reptiles and their role in the spread of Salmonella in the environment. (C) 2014 Elsevier B.V. All rights reserved.
