Ocorrência e fatores de risco da infecção pelo vírus da língua azul em bovinos no Estado de Pernambuco

Abstract: RESUMO: Objetivou-se com este estudo determinar os aspectos epidemiológicos da infecção pelo Vírus da Língua Azul (VLA) em bovinos leiteiros na microrregião de Garanhuns, Estado de Pernambuco, Brasil. Foram coletadas 384 amostras de soro de bovinos fêmeas em idade reprodutiva, procedentes de 20 propriedades dos 19 municípios que compõem a região. As amostras foram testadas com a prova de imunodifusão em gel de agarose (IDGA) para pesquisa de anticorpos anti-VLA. Observou-se ocorrência de 71,3% (274/384; IC 95%… Show more

“…This extremely extensive phase in cattle increases the possibility of the infected animal being targeted by the mosquito vectors, enabling transmission. 12 Moreover, mosquitoes of this genus have a predilection for cattle, which further emphasizes the role of these ruminants as amplifiers of the dissemination of this arbovirus, commonly associated with an asymptomatic infection, which goes unnoticed, contributing to virus maintenance in the herd. 20 Therefore, the easy contact these vectors have with cattle in the BTV viremia phase, subsequently infecting the sheep due to the proximity between these species when managed together, increases the chances of BTV infection in the most vulnerable species.…”

“…transmits the infectious agent to the vector, mainly susceptible animals, lasts up to 120 days. 12 In Brazil, many studies have focused on the seroprevalence and risk factors for BTV infection in cattle, 12,13,14 While few studies analyze risk factors for infection in sheep. 15 Knowing about the bluetongue disease is essential to controlling and mitigating it, considering the relevance of this disease, also called catarrhal fever, and the variety of elements that can increase its occurrence in sheep.…”

“…In addition, vector development and proliferation is favorable in these regions (Dorneles et al, 2012). In Brazil, several studies have shown nationwide prevalence of bluetongue in different domestic and wild ruminant species (Costa, Lobato, Herrmann, Leite, & Haddad, 2006;Alves et al, 2009;Nogueira, Pituco, Stefano, Curci, & Cardoso, 2009;Tomich et al, 2009;Souza, Costa, Martinez, Costa, & Pinheiro, 2010;Mota et al, 2011;Dorneles et al, 2012;Pinheiro et al, 2013;Sbizera et al, 2017;Batista et al, 2018;Silva et al, 2018;Morikawa et al, 2018).…”
