Alterações clínicas e patológicas em ovinos infectados naturalmente pelo vírus da língua azul no Rio Grande do Sul

Abstract: Língua azul (LA) é uma doença causada pelo vírus da língua azul (VLA) e transmitida por vetores do gênero Culicoides. Estudos sorológicos têm demonstrado a ampla presença do vírus no Brasil; entretanto, informações clínicas da LA na América do Sul são limitadas.

“…In Brazil, BTV was first described by Silva (1978) in São Paulo in 1978. After that, several reports have shown that the virus is widespread all over Brazil (Antoniassi, 2010;Costa et al, 2006). Serologic data can be found in the whole country, although the virus was isolated only in two opportunities (Clavijo et al, 2012;Groocock and Campbell, 1982): in 1980, BTV4 was isolated in Florida (USA) from Brazilian zebu cattle which had been quarantined; and in 2001, BTV12 was isolated from sheep showing clinical signs of bluetongue (Clavijo et al).…”

“…Os casos de pleuropneumonias, broncopneumonias e pneumonias fibrinonecrosante ou fibrinossupurativa sem causa definida podem estar associados à infecção por Mannheimia haemolytica (antiga Pasteurella haemolytica) ou por doenças virais, como a língua azul (Araújo et al 2009;Antoniassi et al 2010). Entretanto, os fragmentos coletados durante a necropsia foram apenas conservados em formol, viabilizando somente o exame histopatológico.…”

“…There are at least 26 serotypes of BTV worldwide. 9 In South America, Central America, and the Caribbean, serotypes 1,3,4,6,8,11,12,14, and 17 have been detected by serotype-specific antibodies, and serotypes 1,3,4,6,8,12, and 17 have been detected by virus isolation. 6 In the United States, serotypes 1-3, 5, 6, 9-14, 17, 19, 22, and 24 have been identified.…”
