在2001年春季和夏季，从166个野生爬行动物（94个人）和两栖动物（72个人）从21个不同的物种在西班牙中部发现的粪便进行了检查沙门氏菌的存在。39种爬行动物（41.5%）产生了48株沙门氏菌，而所有的两栖动物检查均为阴性。肠道沙门氏菌（I）亚种占分离株的50%。14个分离物（29.2%）属于diarizonae（IIIb）亚种，6个分离物（12.5%）属于salamae（II）亚种，4个分离物（8.3%）属于arizonae（IIIa）亚种。鉴定了27种不同的血清型。血清型Anatum（12.5%）、Herzliya（8.3%）、Abony，18：l，v：z，9，12：z（29）：1，5和38：z（10）：z（53）（各6.2%）是最常见的分离株。高比例（39.6%）的菌株属于以前与环境源相关的血清型。此外，37.5%的菌株属于与人类沙门氏菌病病例相关的血清型。从这些数据中，可以得出结论，野生爬行动物，但显然不是两栖动物，可能是一个重要的水库沙门氏菌在自然界中，并对公共卫生有潜在的影响。
During the spring and summer of 2001, faeces from 166 wild reptiles (94 individuals) and amphibians (72 individuals) from 21 different species found in central Spain were examined for the presence of Salmonella. Thirty-nine reptiles (41.5%) yielded 48 Salmonella isolates, whereas all the amphibians examined were negative. Subspecies Salmonella enterica enterica (I) accounted for up to 50% of isolates. Fourteen isolates (29.2%) belonged to subspecies diarizonae (IIIb), six isolates (12.5%) to subspecies salamae (II), and four isolates (8.3%) to subspecies arizonae (IIIa). Twenty-seven different serotypes were identified. Serotypes Anatum (12.5%), Herzliya (8.3%), Abony, 18:l,v:z, 9,12:z(29):1,5 and 38:z(10):z(53) (6.2%/each) were the most frequently isolated. A high percentage (39.6%) of isolates belonged to serotypes previously associated with environmental sources. Also, 37.5% of isolates belonged to serotypes which had been related to human cases of salmonellosis. From these data, it is concluded that wild reptiles, but apparently not amphibians, may represent an important reservoir of Salmonella in nature and have potential implications for public health.
