“…The clinical diagnosis of VS is identical to that of foot-and-mouth disease, vesicular exanthema, and swine vesicular disease (OIE, 2004;BONUTTI;FIGUEIREDO, 2005). In the field, differentiation between VS and foot-and mouth disease may be suggested by infection in horses, as the latter does not affect this species (OIE, 2004;BONUTTI;FIGUEIREDO, 2005).…”

“…O monitoramento continuou até 21 dias após a cura clínica do último animal doente quando as três propriedades foram desinterditadas. Palavras-chave: Estomatite vesicular, doença vesicular, bovino, Estado da Paraíba Vesicular stomatitis (VS) is one of the vesicular diseases affecting cattle and swine, a category also including foot-and-mouth disease, vesicular exanthema, and swine vesicular disease, and it cannot be clinically distinguished from foot-andmouth disease (LÓPEZ et al, 1996(LÓPEZ et al, -1997BRIDGES et al, 1997;OIE, 2004;BONUTTI;FIGUEIREDO, 2005). This disease plays an important role in animal health programs, particularly in Brazil, where measures to eradicate foot-and-mouth disease are extensive and clinical vesicular exanthema and swine vesicular disease has not been reported.…”

It is also important to distinguish between VS and infectious bovine rhinotracheitis, bovine viral diarrhea, and bluetongue disease (OIE, 2004).…”

The present report describes the first case of vesicular stomatitis in the State of Paraíba, Brazil. Records from the Official Veterinary Services of the State of Paraíba were analyzed while responding to a suspected case of vesicular disease at a property (property I) in the municipality of Pombal in which the cattle showed clinical signs and lesions of vesicular disease. Surveillance in the surrounding area revealed similar lesions in cattle at two other properties (II and III). Based on these events, the suspicion was considered well founded, and samples were collected for evaluation at the National Agricultural Laboratory of the State of Pará. The property was interdicted, and those located within a 3 km radius (perifocal) from the focus were inspected. At property I, 42.86% (6/14) of the cattle showed vesicular disease lesions characterized by intense sialorrhea, ruptured oral vesicles, epithelial detachment of the tongue and muzzle, and vesicular lesions in the udder and interdigital space. Similar lesions were detected in cattle at properties II and III, affecting 80.95% (34/42) and 11.54% (3/26) of the animals, respectively. Tissue samples collected from the three properties were positive for the vesicular stomatitis virus (Indiana 3 subtype). The properties were monitored for 21 days after the last infected animal was cured, and afterwards, the three properties were released.

Foram analisados os documentos produzidos pelo Serviço Veterinário Oficial do Estado da Paraíba durante o atendimento de uma notificação de suspeita de doença vesicular em uma propriedade (propriedade I) do município de Pombal em que bovinos apresentavam sinais clínicos e lesões compatíveis com doença vesicular. Durante a vigilância das propriedades vizinhas, em outras duas propriedades (II e III) foram encontradas lesões similares. Diante desse quadro, a suspeita foi considerada fundamentada e foi feita a colheita de material para diagnóstico no Laboratório Nacional Agropecuário no Estado do Pará (LANAGRO-PA), interdição da propriedade e investigação das propriedades de um raio de

“…It is considered one of the serotypes of vesicular stomatitis virus (VSV) [8]. Cocal virus is important for veterinary public health, as it is one of the causal agents of vesicular stomatitis [9]. Infection in humans may be asymptomatic or accompanied by myalgia, headache, and fever, which are cured within three to five days without complications [10].…”

We previously demonstrated, using the Piry virus model, that environmental enrichment promotes higher T-cell infiltration, fewer microglial changes, and faster central nervous system (CNS) virus clearance in adult mice. However, little is known about disease progression, behavioral changes, CNS cytokine concentration, and neuropathology in limbic encephalitis in experimental models. Using Cocal virus, we infected C57Bl6 adult mice and studied the neuroanatomical distribution of viral antigens in correlation with the microglial morphological response, measured the CNS cytokine concentration, and assessed behavioral changes. C57Bl6 adult mice were maintained in an impoverished environment (IE) or enriched environment (EE) for four months and then subjected to the open field test. Afterwards, an equal volume of normal or virus-infected brain homogenate was nasally instilled. The brains were processed to detect viral antigens and microglial morphological changes using selective immunolabeling. We demonstrated earlier significant weight loss and higher mortality in IE mice. Additionally, behavioral analysis revealed a significant influence of the environment on locomotor and exploratory activity that was associated with less neuroinvasion and a reduced microglial response. Thus, environmental enrichment was associated with a more effective immune response in a mouse model of limbic encephalitis, allowing faster viral clearance/decreased viral dissemination, reduced disease progression, and less CNS damage.
