Abstract

The occurrence of Equine Eastern Encephalomyelitis (EEE), Equine Western Encephalomyelitis (WEE) and Equine Venezuelan Encephalomyelitis (VEE) virus infection was investigated in equids not vaccinated against these viruses. The animals were distributed  in ten regional districts of the state of Minas Gerais (Almenara, Bambuí, Curvelo, Governador Valadares, Montes Claros, Oliveira, São Gonçalo do Sapucaí, Teófilo Otoni, Unaí e Viçosa). Microplate serum neutralization test was used to detect antibodies against encephalitis virus. Two hundred and fifty animals (30.2%, 250/826) were EEE-seropositive, while 1.9% of them (16/826) were VEE-seropositive. No animals were found to be seropositive for WEE. In conclusion, either EEE or VEE viruses circulate in the equid population of the state of Minas Gerais.
