Abstract

Leptospirosis and toxoplasmosis are re-emerging zoonosis caused by infection with pathogenic spirochaetes of Leptospira and the protozoa Toxoplasma gondii, respectively. Wild boars (Sus scrofa), an exotic invasive species in Brazil, could play a role in the diseases’ epidemiological cycles, but this issue is still unexplored. This study aimed to evaluate the Leptospira spp. and T. gondii seropositivity in wild boars in Rio Grande do Sul state, south Brazil. Of evaluated animals, 16% (13/80) and 85% (52/61) had antibodies to T. gondii and Leptospira spp., respectively. Sex, weight, age, hunt location and season of hunt were evaluated by their association with seropositivity for both pathogens, but none of them had statistical significance. This study revealed that wild boars should be considered as a potential source of Leptospira spp. and T. gondii dissemination for humans and animal species in shared environments in Rio Grande do Sul state.

评估野猪（Sus scrofa）的钩端螺旋体病和弓形虫血清阳性反应：对巴西南部公共卫生和动物健康的影响

钩端螺旋体病和弓形虫病是重新出现的人畜共患疾病，分别由钩端螺旋体的致病螺旋体和弓形虫原虫感染引起。野猪（Sus scrofa）是巴西的外来入侵物种，可能在这些疾病的流行周期中扮演重要角色，但这一问题仍未得到探讨。本研究旨在评估巴西南部南里奥格兰德州野猪的钩端螺旋体属和淋病双球菌血清阳性率。在接受评估的动物中，分别有16%（13/80）和85%（52/61）的动物体内有钩端螺旋体和钩端螺旋体抗体。性别、体重、年龄、狩猎地点和狩猎季节与这两种病原体血清阳性反应的关系进行了评估，但均无统计学意义。这项研究表明，在南里奥格兰德州的共同环境中，野猪应被视为人类和动物物种传播钩端螺旋体和淋病双球菌的潜在来源。

期刊介绍： Comparative Immunology, Microbiology & Infectious Diseases aims to respond to the concept of "One Medicine" and to provide a venue for scientific exchange. Based on the concept of "Comparative Medicine" interdisciplinary cooperation between specialists in human and animal medicine is of mutual interest and benefit. Therefore, there is need to combine the respective interest of physicians, veterinarians and other health professionals for comparative studies relevant to either human or animal medicine . The journal is open to subjects of common interest related to the immunology, immunopathology, microbiology, parasitology and epidemiology of human and animal infectious diseases, especially zoonotic infections, and animal models of human infectious diseases. The role of environmental factors in disease emergence is emphasized. CIMID is mainly focusing on applied veterinary and human medicine rather than on fundamental experimental research.
