Oropouche and Mayaro viruses are enzootic arboviruses of public health concern throughout Latin America. Recent outbreaks of OROV in northern region and sporadic autochthonous cases in western region of Brazil, suggest a silent circulation of these neglected viruses. Aiming to investigate the exposure of different species of domestic animals to MAYV and OROV in urban and peri-urban areas of West-Central Brazil, we performed a cross-sectional serosurvey by plaque reduction neutralization test (PRNT). Our findings included neutralizing antibodies for both arboviruses in cattle, dogs and horses, suggesting eventual role of domestic animals in enzootic arbovirus surveillance in Brazil.
奥罗普切病毒和马亚罗病毒是拉丁美洲各地备受公共卫生关注的地方性虫媒病毒。近期巴西北部地区奥罗普切病毒的爆发以及西部地区偶发的本地病例表明，这些被忽视的病毒正在悄然传播。为了调查巴西中西部城市和城郊地区不同家畜物种对马亚罗病毒和奥罗普切病毒的暴露情况，我们通过蚀斑减少中和试验（PRNT）进行了一项横断面血清学调查。我们的研究结果包括在牛、狗和马体内发现了针对这两种虫媒病毒的中和抗体，这表明家畜在巴西地方性虫媒病毒监测中可能发挥着作用。
