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.
钩端螺旋体病和弓形虫病分别是由致病性螺旋体钩端螺旋体和原生动物刚地弓形虫感染引起的重新出现的动物源性传染病。野猪（Sus scrofa）是巴西的一种外来入侵物种，可能在这些疾病的流行病学循环中发挥作用，但这一问题仍未得到探索。本研究旨在评估南里奥格兰德州巴西野猪中钩端螺旋体 spp. 和刚地弓形虫的血清阳性率。在所评估的动物中，分别有 16%（13/80）和 85%（52/61）的动物对刚地弓形虫和钩端螺旋体 spp. 具有抗体。通过分析性别、体重、年龄、狩猎地点和狩猎季节与两种病原体血清阳性率的关系，发现这些因素均与血清阳性率无统计学意义。本研究表明，野猪应被视为南里奥格兰德州共享环境中人类和动物物种中钩端螺旋体 spp. 和刚地弓形虫传播的潜在来源。
