In the present study, we serosurveyed the exposure of 222 draft horses to different arboviruses in the city of Santa Fe, Argentina. Plaque reduction neutralization tests confirmed exposure to Fort Sherman virus (FSV), Saint Louis encephalitis virus (SLEV), West Nile virus (WNV), and Río Negro virus (RNV). Apparently, Western and Eastern equine encephalitis viruses did not circulate in the population tested. The confirmation of five seroconversions for WNV, FSV, and SLEV and the association between prevalence and age are indicative of recent circulation. These results highlight the importance of considering draft horses in arboviral surveillance in urban and rural areas of developing countries.
在本研究中，我们对阿根廷圣菲市的 222 匹役马进行了血清学调查，以了解它们对不同虫媒病毒的暴露情况。噬斑减少中和试验证实了它们对福尔斯·舍尔曼病毒（FSV）、圣路易斯脑炎病毒（SLEV）、西尼罗河病毒（WNV）和里奥内格罗病毒（RNV）的暴露。显然，西部和东部马脑炎病毒并未在检测的人群中传播。5 匹马对 WNV、FSV 和 SLEV 的血清转化得到确认，且流行率与年龄相关，这表明最近有病毒循环。这些结果突出表明，在发展中国家的城乡地区进行虫媒病毒监测时，有必要考虑役马。
