The fecal samples from 213 captive reptiles were examined, and 29 (13.61%) Salmonella enterica isolates were detected: 14/62 (22.58%) from chelonians, 14/135 (10.37%) from saurians, and 1/16 (6.25%) from ophidians. The isolates were distributed among 14 different serotypes: Miami, Ebrie, Hermannsweder, Tiergarten, Tornov, Pomona, Poona, Goteborg, Abaetetube, Nyanza, Kumasi, Typhimurium, 50:b:z6, 9,12:z29:1,5, and a non-motile serotype with antigenic formula 1,4,[5],12:-:-. Salmonella typhimurium and 50:b:z6 isolates showed the spv plasmid virulence genes, responsible of the capability to induce extra-intestinal infections. In some cases, pulsed field gel electrophoresis revealed different profiles for the strains of the same serotypes, showing different origins, whereas a common source of infection was supposed when one pulsotype had been observed for isolates of a serovar. Twenty-seven (93.10%) isolates showed resistance to one or more antibiotics. Ceftazidime was active to all the tested isolates, whereas the highest percentages of strains were no susceptible to tigecycline (93.10%), streptomycin (89.66%), and sulfonamide (86.21%).
对213份圈养爬行动物的粪便样本进行了检测，检测到29株（13.61%）肠炎沙门氏菌分离株：龟类中分离出14/62株（22.58%），蜥蜴类中分离出14/135株（10.37%），蛇类中分离出1/16株（6.25%）。这些分离株分布在14种不同的血清型中：迈阿密、埃布里、赫曼斯韦德尔、动物园、托尔诺夫、波莫纳、普纳、哥德堡、阿贝泰图贝、尼亚萨、库马西、鼠伤寒、50:b:z6、9,12:z29:1,5，以及一种抗原公式为1,4,[5],12:-: -的无动力血清型。鼠伤寒沙门氏菌和50:b:z6分离株显示出spv质粒毒力基因，该基因负责诱导肠外感染的能力。在某些情况下，脉冲场凝胶电泳显示相同血清型菌株的图谱不同，表明来源不同，而当一个血清型的分离株观察到一种脉冲型时，则推测存在共同感染源。27株（93.10%）分离株对一种或多种抗生素耐药。头孢他啶对所有测试分离株均有活性，而最高比例的菌株对替加环素（93.10%）、链霉素（89.66%）和磺胺类药物（86.21%）不敏感。
