Meningoencefalite por Herpesvirus bovino 5 em Minas Gerais: relato de caso clínico

Abstract: RESUMORelata-se um caso de meningoencefalite causada por Herpesvirus bovino 5 (BoHV-5) heritabilityem uma vaca com cinco anos de idade. O animal manifestou quadro clínico inicial de síndrome medular baixa, caracterizada por incoordenação dos membros pélvicos, sinais estes ainda não descritos para a enfermidade. Dentro de pouco tempo a doença evoluiu para síndrome cerebral, e o óbito ocorreu seis dias após o inicio dos sintomas. Na histopatologia, evidenciou-se meningoencefalite difusa, não supurada, e a confir… Show more

“…The clinical history of animals positive for BoHV5 consisted of apathy, sialorrhea, inappetence, head tremors, low head, ataxia, reduced visual acuity, bilateral nasal discharge, and oligopneic breathing associated with expiratory dyspnea. The clinical course of the affected animals was 6 days, showing the high lethality of the involved agent, which is in accordance with the findings described by Aquino Neto et al (2009). The variation of signs depends on factors such as the presence of concomitant diseases, including polioencephalomalacia (David, 2002), which markedly accentuate the lesions of meningoencephalitis, and the immune status of the animals (Belknap et al, 1994) proved by the action of passive immunity in the protection of animals exposed to the virus, and the viral sample.…”

“…In addition, the low frequency of disease reports caused by BoHV5 is related to the difficulty in identifying the cause due to the similarity of the clinical signs and the difficulty in performing differential diagnoses. This is due to the multiple signs or lack of technical structure in the laboratories (Aquino Neto et al, 2009) added to the lack of knowledge of BoHV5 occurrence in the region or the particularities associated with the infection by the agent.…”

“…Fato semelhante ocorreu em casos descritos no Paraná (Massitel et al 2016) e em Mato Grosso (Colodel et al 2002). Alguns autores relataram casos da doença em animais manejados em sistema de criação extensivo (Salvador et al 1998, Colodel et al 2002, Elias et al 2004, semi-intensivo (Barros et al 2006, Aquino Neto et al 2009 e intensivo (Elias et al 2004, Cunha et al 2009, Lunardi et al 2009, submetidos a situações de estresse, principalmente desmama precoce (Rissi et al 2006).…”

“…A meningoencefalite tem sido observada em várias regiões do mundo e, no Brasil, surtos de rinotraqueíte, vulvovaginite e balanopostite são diagnosticados em várias regiões do país. A meningoencefalite associada ao BoHV-5 é uma doença infecto-contagiosa que afeta principalmente bovinos jovens e têm sido reportada em vários estados brasileiros, como Rio Grande do Sul (Riet-Correa et al 1989, Sanches et al 2000, Elias et al 2004, Rissi et al 2006, Silva et al 2007, Rissi & Barros 2013, Paraná (Claus et al 2007, Lunardi et al 2009, Massitel et al 2016, Rio de Janeiro, Minas Gerais (Gomes et al 2002, Claus et al 2007, Franco & Roehe 2007, Aquino Neto et al 2009, Mato Grosso (Colodel et al 2002, Claus et al 2007, Arruda et al 2010, Pernambuco (Oliveira et al 2014), Paraíba, Rio Grande do Norte (Galiza et al 2010), Pará (Riet-Correa et al 2006, São Paulo (Claus et al 2007, Ferrari et al 2007, Cunha et al 2009 e Mato Grosso do Sul (Salvador et al 1998, Gomes et al 2002, Lemos 2005, Claus et al 2007, Silva et al 2007.

“…Although meningoencephalitis caused by BoHV-5 primarily affects young animals, it may also affect adults (Salvador et al, 1998;Elias et al, 2004;Rissi et al, 2008;Aquino Neto et al, 2009;Cunha et al, 2009). Indeed, BoHV-5 has been described in animals from 1 (Rissi et al, 2008) to 60 months of age (Salvador et al, 1998;Aquino Neto et al, 2009). …”
