Abstract

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.

巴西中西部城市和城市周边地区家畜接触马雅罗病毒和奥罗普切病毒的情况。
奥罗普切病毒和马亚罗病毒是引起整个拉丁美洲公共卫生关注的流行性虫媒病毒。最近在巴西北部地区爆发的奥罗普切病毒和西部地区的零星自发病例表明,这些被忽视的病毒正在悄然流行。为了调查巴西中西部城市和城市周边地区不同种类家畜接触 MAYV 和 OROV 的情况,我们通过斑块还原中和试验(PRNT)进行了一次横断面血清调查。我们的研究结果表明,牛、狗和马体内都存在这两种虫媒病毒的中和抗体,这表明家畜在巴西的虫媒病毒监测中最终会发挥作用。
