First case report of vesicular stomatitis in the State of Paraíba, Brazil

Abstract

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

Vesicular stomatitis due to Indiana III (Alagoas/VSIV-3) is endemic in Brazilian state of Ceará

“…The Indiana III viral serotype has been frequently detected in the northeastern states in recent years, confirming its endemic trait in the region. The agent was isolated from the bovine tongue and serum epithelium in 2010 and 2016 in Paraíba (CLEMENTINO et al, 2014;BEZERRA et al, 2018) and in 2013 in Maranhão (ARRUDA et al, 2015). CARGNELUTTI et al (2014) also detected the presence of VSIV in vesicular fluid and oral epithelium samples of equine and bovine in the states of Rio Grande do Norte and Paraíba.…”

“…This situation indicated the need for a greater number of substantiated reports so that explanatory variables can serve as a preventive basis for epidemiological studies. During the epidemiological investigation of outbreaks in Paraíba, CLEMENTINO et al (2014) concluded that it was impossible to identify the origin of the virus as no significant entry of VS-susceptible animals into areas within 3 km from the outbreak was detected 30 days before disease onset. Several studies have reported that it is often impossible to identify the source of the infection and its reservoirs (DE STEFANO et al, 2002;SEPÚLVEDA et al, 2007).…”

“…Epidemiologically important variants of the vesicular stomatitis (VS) in Brazil are the Indiana II and III viral subtypes. The Indiana II viral subtype was isolated in the states of São Paulo and Rio Grande do Sul in two separate episodes with 10-year difference and with no evidence of epidemiological connection between them (LÓPEZ- INZAURRALDE, 1997;CLEMENTINO et al, 2014). In 1998 and1999, in the states of Paraná and Santa Catarina, two outbreaks of EV were recorded by the Indiana II viral subtype, and until 2011, there was no record of this viral subtype in the country.…”
