Leptospirosis is a neglected bacterial zoonotic disease of worldwide distribution that is present in different animal species. This epidemiological study determined the seroprevalence of pathogenic spp. in animals at a wildlife rehabilitation center in Puerto Montt, southern Chile, by sampling 60 animals belonging to three classes (birds, mammals, and reptiles). Diagnosis was performed using the microscopic agglutination test with a panel of eight serovars and serogroups. The results showed that 15 animals had anti- antibodies, obtaining a seroprevalence of 25.00%, with serogroup Tarassovi presenting reactivity in 13 of the seropositive animals. Among the classes of mammals, chilla foxes () and pudus () were seropositive. A guiña () was also seropositive, which was described for the first time in mammals. Among the classes of birds, choroy parrots (), bandurrias (), and Magellanic penguins ) were seropositive. Routine examinations to diagnose leptospirosis, perform epidemiological surveillance, and apply prevention and control measures are necessary, and additional research focusing on the One Health approach to explore the epidemiological role of different wild animal species in the maintenance and transmission of leptospirosis at the local and global levels are recommended.
钩端螺旋体病是一种被忽视的细菌性人畜共患病,在全球范围内分布,存在于不同动物物种中。这项流行病学研究通过对智利南部蒙特港一个野生动物康复中心的60只分属三类(鸟类、哺乳动物和爬行动物)的动物进行采样,确定了致病性钩端螺旋体属的血清阳性率。使用一组八种血清型和血清群通过显微镜凝集试验进行诊断。结果显示,15只动物有抗钩端螺旋体抗体,血清阳性率为25.00%,其中塔拉索维血清群在13只血清阳性动物中呈现反应性。在哺乳动物类别中,智利狐和普度鹿血清呈阳性。一只草原猫也呈血清阳性,这在哺乳动物中是首次被描述。在鸟类类别中,乔罗伊鹦鹉、斑鸠和麦哲伦企鹅血清呈阳性。有必要进行常规检查以诊断钩端螺旋体病、开展流行病学监测并采取预防和控制措施,建议开展更多聚焦“同一健康”方法的研究,以探索不同野生动物物种在当地和全球层面维持和传播钩端螺旋体病中的流行病学作用。
