Resumo: Serum samples from 89 equids were analyzed (75 horses, 9 donkeys, and 5 mules) from the municipality of Viseu, Pará state, Brazil. Samples were collected in November 2014 and August 2015. The antibody prevalence against the following alphaviruses was estimated: Eastern equine encephalitis virus, Western equine encephalitis virus, Mucambo virus, and Mayaro virus. Seroprevalence was determined by the hemagglutination inhibition (HI) technique. Sera that exhibited HI antibodies with heterotypic reactions for the analyzed viruses were subjected to the 90% plaque reduction neutralization test (PRNT90). The HI prevalence of monotypic reactions to EEEV was 7.9%, and that of WEEV was 1.1%, as confirmed by PRNT90. Viral isolation attempts were negative for all tested blood samples. Our results suggest the circulation of equine encephalitis complex viruses. Future studies should evaluate the possible involvement of arthropod hosts and residents in the viral transmission in the study area.

As amostras foram coletadas no período de novembro de 2014 e agosto de 2015. Foram estimadas as prevalências de anticorpos contra os seguintes Alfavírus: vírus da Encefalite equina leste (EEEV), vírus da Encefalite equina oeste (WEEV), vírus Mucambo (MUCV), and vírus Mayaro (MAYV). A soroprevalência foi determinada por técnicas de Inibição da Hemaglutinação (IH), porém os soros que apresentaram anticorpos IH com reações heterotípicas para os vírus analisados foram submetidos ao PRNT90. A prevalência de reações monotípicas por IH para EEEV foi de 7, 9% e para WEEV foi de 1,1%, confirmadas por PRNT90. A tentativa de isolamento viral foi negativa em todas as amostras de sangue testadas. Nossos resultados sugerem a circulação de vírus do complexo das encefalites equinas. Estudos futuros devem ser realizados para avaliar possível envolvimento de hospedeiros artrópodes e residentes na área de abrangência do estudo.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2021-03-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdftext/xmlhttps://rbmv.org/BJVM/article/view/117010.29374/2527-2179.bjvm001720Brazilian Journal of Veterinary Medicine; Vol. 43 No. 1 (2021); e001720Revista Brasileira de Medicina Veterinária; v. 43 n. 1 (2021); e0017202527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVenghttps://rbmv.org/BJVM/article/view/1170/1156https://rbmv.org/BJVM/article/view/1170/1201Copyright (c) 2021 Josynélia do Socorro da Silva Sena Nunes, Lívia Medeiros Neves Casseb, Ricardo José de Paula Sousa Guimarães, Wilgner Duarte Magalhães Reis, Bruno de Cássio Veloso de Barros, Milene Silveira Ferreira, Jannifer Oliveira Chiang, Helder Henrique Costa Pinheiro, Pedro Fernando da Costa Vasconcelos, Ana Cecília Ribeiro Cruzhttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessdo Socorro da Silva Sena Nunes, Josynélia Medeiros Neves Casseb, Lívia de Paula Sousa Guimarães, Ricardo José Duarte Magalhães Reis, Wilgner de Cássio Veloso de Barros, Bruno Silveira Ferreira, Milene Oliveira Chiang, Jannifer Costa Pinheiro, Helder Henrique da Costa Vasconcelos, Pedro Fernando Ribeiro Cruz, Ana Cecília2022-06-26T21:23:35Zoai:ojs.rbmv.org:article/1170Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2022-06-26T21:23:35Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false
