Resumo: Three outbreaks of herpesvirus meningoencephalitis in cattle have been reported in three municipalities in the northern region of the State of Tocantins, Brazil. In one outbreak, 41 predominantly young bovines were affected, with 2–3 deaths in some cases. The animals showed neurological signs of incoordination, blindness, and recumbency, with death occurring within approximately 4–5 d. At necropsy, hyperemia and leptomeningeal hemorrhages were observed in the brain. Histology revealed more intense lesions in the rostral portions of the brain, mainly affecting the frontoparietal cerebral cortex, with nonsuppurative encephalitis and meningitis, glial nodules, neuronophagia, and eosinophilic intranuclear inclusion bodies in the astrocytes and neurons. This study shows the presence of bovine herpesvirus in Tocantins, probably the highly neurotropic type 5 strain, and emphasizes its importance in the differential diagnosis of bovine neuropathies.

Num surto, 41 animais predominantemente jovens foram afetados, com 2–3 mortes nos outros casos. Os animais apresentaram sinais neurológicos de incoordenação, cegueira e decúbito, com a morte ocorrendo em aproximadamente 4 a 5 dias. Na necropsia foram observadas hiperemia e hemorragias leptomeníngeas no encéfalo. A histologia revelou lesões mais intensas nas porções rostrais do encéfalo, principalmente no córtex cerebral frontoparietal, com encefalite e meningite não supurativas, nódulos gliais, neuronofagia e corpúsculos de inclusão intranucleares eosinofílicos nos astrócitos e neurônios. Este estudo demonstra a presença do herpesvírus bovino no Tocantins, provavelmente a cepa tipo 5 altamente neurotrópica, e enfatiza sua importância no diagnóstico diferencial das neuropatias bovinas.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2024-01-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdftext/xmlhttps://bjvm.org.br/BJVM/article/view/132210.29374/2527-2179.bjvm004023Brazilian Journal of Veterinary Medicine; Vol. 46 (2024); E004023Revista Brasileira de Medicina Veterinária; v. 46 (2024); E0040232527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVenghttps://bjvm.org.br/BJVM/article/view/1322/1385https://bjvm.org.br/BJVM/article/view/1322/1388Copyright (c) 2024 Ilgner Aimar Bezerra Pinheiro, Bianca Pereira Dias, Jardel Martins Ferreira, Alessandro José Ferreira dos Santos, Sandro Estevan Moron, Gilzelle Maria da Luz Silva, Liana Bezerra Dias de Lima, Fabiano Mendes de Cordovahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPinheiro, Ilgner Aimar BezerraDias, Bianca PereiraFerreira, Jardel Martinsdos Santos, Alessandro José FerreiraMoron, Sandro EstevanSilva, Gilzelle Maria da Luzde Lima, Liana Bezerra Diasde Cordova, Fabiano Mendes2024-02-09T13:35:26Zoai:ojs.rbmv.org:article/1322Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2024-02-09T13:35:26Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false
