Abstract：
Reptiles, including snakes, can be asymptomatically infected with multiple pathogen microorganisms, including Salmonella spp., which is considered an important concern for public and animal health. Small and uninhabited isles are quite ecologically different from mainland and represent interesting fields of study, to discover unexpected biological and microbiological aspects of their wild inhabitants. This work reports the presence of the very rare Salmonella enterica serovar Yopougon, isolated in a carcass of a native wild snake (Hierophis viridiflavus) from an Italian uninhabited island of Mediterranean Sea, Montecristo. To our knowledge, S. enterica serovar Yopougon was previously isolated only once 34 years earlier in Ivory Coast, from a human fecal sample. In the present study, we present the genomic characterization of the new isolate, the phylogenetic comparison with the previously isolated S. enterica serovar Yopougon strain of human origin and with other sequences available in public databases. In addition, an extensive review of available data in the literature and from our case history is provided. Our finding represents an example of the ability of some pathogens to travel for very long distances within their hosts and then to infect others, even from different taxa.
摘要：
爬行动物,包括蛇,可以被多种病原体微生物无症状感染，包括沙门氏菌.,这被认为是公众和动物健康的重要问题。小而无人居住的小岛在生态上与大陆截然不同，代表着有趣的研究领域，发现野生居民意想不到的生物学和微生物学方面。这项工作报告了非常罕见的肠道沙门氏菌的存在，隔离在来自地中海的一个意大利无人居住的岛屿的本地野生蛇（Hierophisviridiflavus）的尸体中，蒙特克里斯托.据我们所知,美国肠杆菌血清型Yopougon以前只在34年前在象牙海岸被隔离过一次，来自人类粪便样本。在本研究中,我们介绍了新分离株的基因组特征，与先前分离的人类来源的肠球菌血清变型Yopougon菌株以及公共数据库中可用的其他序列的系统发育比较。此外,提供了对文献和我们病例史的现有数据的广泛回顾.我们的发现代表了一些病原体在其宿主内传播很长一段距离然后感染其他病原体的能力的一个例子，甚至来自不同的分类单元。
