Reptiles are well-known reservoirs of Salmonella spp. and cases of reptile-associated salmonellosis (RAS) are increasing since reptiles are becoming more popular as pets. In the present study, the presence, distribution and prevalence of serovars of Salmonella was investigated in captive snakes (n = 87) and in free-living snakes (n = 87) in Germany. A total of 43 S. enterica-isolates were recovered from organ samples and cloacal swabs, predominantly belonging to the subspecies diarizonae (IIIb) (n = 27), enterica (I) (n = 7) and houtenae (IV) (n = 6). S. enterica subsp. enterica (I) serovar Paratyphi B (n = 4) and S. enterica subsp. diarizonae (IIIb) serovar 47:l,v:z (n = 3) were the most frequently isolated serotypes. Nevertheless, the fact that most serotypes were only represented by a single isolate points out the high diversity of Salmonella present among snakes. Salmonella enterica subsp. diarizonae (IIIb) serotype 40:i:z53, which was isolated twice from two free-living Eurasian adders (Vipera berus) captured at different locations, has not been previously described. Our results confirm the role of both free-living and captive snakes as reservoirs of S. enterica in Germany.
爬行动物是沙门氏菌属的著名宿主，随着爬行动物作为宠物越来越受欢迎，与爬行动物相关的沙门氏菌病（RAS）病例也在增加。在本研究中，对德国圈养蛇（n = 87）和自由生活蛇（n = 87）中沙门氏菌血清型的存在、分布和流行情况进行了调查。从器官样本和泄殖腔拭子中总共分离出43株肠炎沙门氏菌，主要属于亚利桑那亚种（IIIb）（n = 27）、肠炎亚种（I）（n = 7）和豪顿亚种（IV）（n = 6）。肠炎沙门氏菌亚种肠炎（I）血清型副伤寒B（n = 4）和肠炎沙门氏菌亚种亚利桑那（IIIb）血清型47:l,v:z（n = 3）是最常分离出的血清型。然而，大多数血清型仅由单个分离株代表这一事实表明蛇体内存在的沙门氏菌具有高度多样性。从不同地点捕获的两条自由生活的欧亚蝰蛇（Vipera berus）中两次分离出的肠炎沙门氏菌亚种亚利桑那（IIIb）血清型40:i:z53，此前尚未见报道。我们的结果证实了自由生活蛇和圈养蛇在德国作为肠炎沙门氏菌宿主的作用。
