Abstract
The Bluetongue disease is an infectious and non-contagious viral disease mainly transmitted through hematophagous vector of the Culicoides genus, to domestic and wild ruminants. The aim of this study was to evaluate the antibodies occurrence, persistence and potential risk factors associated with bluetongue virus infection in sheep flocks in the state of Parana, Brazil. The competitive ELISA test was applied to evaluate 690 blood serum samples from 22 farms in eight mesoregions of Parana in 2014, and 270 sheep blood serum samples from 10 of the 22 previously studied farms in 2017. A questionnaire was applied to evaluate the risk factors associated with BTV infection. In 2014 and 2017, the numbers of seroreactive sheep were found to be 28.26% (195/690) and 41.11% (111/270), respectively, representing 95.45% (21/22) and 90% (9/10) of the flocks. The significant variables considered as risk factors were Culicoides presence (P < 0.0001; OR = 8.83 and 95% CI 4.28-18.22); genealogical record (P < 0.0001; OR = 0.23 and 95% CI 0.12-0.45) and use of sheepfold (P = 0.0208; OR = 0.36 and 95% CI 0.15-0 0.86). It was determined that BTV infection is endemic in Parana and persists in the mesoregions where the climate is favorable to vector proliferation.

Abstract
Bluetongue virus (BTV) is an RNA virus that infects cattle and sheep. The objective of this study was to compare two real-time PCRs for the detection of BTV and to monitor Orbivirus viremia in sheep and cattle for 6 months. The PCR results showed the occurrence of infected animals throughout the experiment without records of clinical signs. The number of positive animals reduced during the experiment, but some animals were positive for BTV RNA during the entire experiment. The performance of the two RT-qPCRs for BTV detection techniques used in this work revealed a kappa index of 0.71 for cattle and 0.75 for sheep.

Abstract
ABSTRACT The present review aims to show the main aspects related to bluetongue virus (BTV) infection in sheep. The bluetongue (BT) is a viral, infectious, and non-contagious disease caused by a virus (BTV) of the Orbivirus genus, transmited by a hematophagous vector of the Culicoides genus, to domestic and wild ruminants, mainly to sheep, the most susceptible species. It is caused by the association of endemic with climate conditions, with high temperatures and humidity. Economic loss is directly linked to death, abortion, weight loss, loss of milk, and meat production, and, indirectly, to the restriction on the export of animals and their by-products. The study concludes that the BTV is worldwidely spread, and probably persists due to the warm and humid climate that leads to the proliferation of Culicoides sp., being necessary to adopt measures that reduce the risk factors associated to the BTV infection.

Abstract
ABSTRACT: Bluetongue (BT) is an infectious and non-contagious disease of compulsory notification which may affect domestic and wild ruminants, transmitted by Culicoides spp. midges. Despite the high morbidity and mortality in sheep, role of wild animals in the BT cycle remains unclear. Caprine arthritis-encephalitis (CAE) and Maedi-Visna virus (MVV) have been reportedly found in goats and sheep, but not described in wildlife species. Accordingly, serum samples from 17 captive Barbary sheep (Ammotragus lervia) from Curitiba zoo, southern Brazil, were tested for bluetongue, caprine arthritis-encephalitis (CAE) and Maedi-Visna viruses by agar gel immunodiffusion (AGID) and enzyme linked immunosorbent assay (ELISA). Antibodies for bluetongue were observed in 6/17 (35.3%) Barbary sheep by AGID test and in 7/17 (41.2%) by ELISA. All samples were negative for the presence of antibodies against caprine arthritis-encephalitis (CAE) and Maedi-Visna viruses. These findings indicate that Barbary sheep may be infected by bluetongue virus and act as wildlife reservoir in both captive and free-range environments.

Abstract
Culicoides biting midges (Diptera: Ceratopogonidae) are of great medical and veterinary importance because the haematophagous females of some species can transmit diseases to humans and animals. In order to determine the presence and seasonal abundance of the bluetongue virus (BTV) vector Culicoides insignis Lutz at domestic animal sheds in northeastern Brazil, insects were collected once a month between January and December 2010. Light traps were set from 18.00 to 06.00 hours at a pigsty, chicken coop and bovine corral. Culicoides insignis accounted for 81% of the 22,316 specimens collected. Other well-represented species were: Culicoides paucienfuscatus Barbosa (3246 individuals), Culicoides diabolicus Hoffman (308), Culicoides leopoldoi Ortiz (224) and Culicoides duartei Tavares and Luna Dias (221). The remainder accounted for 4% of the total sample. Culicoides insignis occurred mostly at the cattle corral, 98.2% in the rainy season. This study confirms the presence and close association of C. insignis with cattle in Maranhão state, northeastern Brazil and emphasizes the risk of bluetongue infections spreading in the area.

Abstract
O objetivo deste trabalho foi avaliar a ocorrência de ovinos soropositivos para o vírus da língua azul (VLA) no Estado do Ceará, Brasil, e analisar as proteínas imunogênicas das cepas virais circulantes nesses rebanhos. O teste de imunodifusão em gel de agarose (IDGA) foi utilizado para pesquisar 271 amostras de soro oriundas de 16 rebanhos. Os resultados demonstraram que 27,3% (74/271) das amostras analisadas apresentaram anticorpos contra o agente e 68,8% (11/16) das propriedades tiveram animais positivos. O immunoblotting (IB) foi utilizado para analisar as proteínas imunogênicas do VLA a partir dos soros de animais positivos no IDGA. Os soros demonstraram forte reação contra a proteína viral VP2. Para o VLA, das sete proteínas estruturais, a VP2 é a principal a estimular a resposta imune protetora. Concluiu-se que a soropositividade para a língua azul (LA) nos rebanhos ovinos estudados no Ceará é alta, apesar dos animais não apresentarem sinais clínicos, indicativo de que o vírus ocorra de forma endêmica. Além disso, a resistência à doença apresentada pelos animais pode estar relacionada com a forte reação imunológica desses à proteína VP2. Sendo assim, outros estudos são necessários para melhor esclarecer a situação epidemiológica da LA no país, através da identificação dos vetores e sorotipos virais circulantes nas diferentes regiões.

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. Esse trabalho descreve alterações clínico-patológicas em ovinos acometidos pela LA no Sul do Brasil. Em dois surtos, em propriedades distintas, 15 ovinos apresentaram como principais sinais clínicos hipertermia, apatia, aumento de volume da face e região submandibular, dificuldade de deglutição com regurgitação, secreção nasal mucopurulenta esverdeada, alterações respiratórias, além de acentuada perda de peso e erosões na mucosa oral. Os achados de necropsia em seis ovinos afetados incluíram edema subcutâneo na face e região ventral do tórax, secreção nasal esverdeada, esôfago dilatado preenchido por grande quantidade de conteúdo alimentar, pulmões não colabados com áreas consolidadas anteroventrais, bem como luz da traquéia e brônquios preenchida por espuma misturada com conteúdo alimentar. No coração e base da artéria pulmonar, havia focos de hemorragia. Histologicamente, as principais alterações observadas ocorriam no tecido muscular cardíaco e esquelético, especialmente no esôfago e consistiam de lesões bifásicas caracterizadas por degeneração/necrose hialina e flocular de miofibras associadas com micro-calcificação e infiltrado inflamatório mononuclear. Pneumonia aspirativa associada à presença de material vegetal e bactérias na luz de brônquios também foi observada. O diagnóstico de LA foi confirmado pela detecção do genoma viral por duplex RT-PCR em amostras de sangue de animais afetados, seguido da identificação do VLA, sorotipo 12 por sequenciamento.

Abstract
RESUMO O objetivo desta pesquisa foi verificar a frequência de ovinos soropositivos para o vírus da língua azul na microrregião de Juazeiro, Bahia. O teste de imunodifusão em gel de ágar (IDGA) foi utilizado para pesquisar 469 amostras de soro oriundas de 58 rebanhos. Durante as colheitas, um questionário foi aplicado a cada criador a fim de se obter dados sobre o sistema de criação e correlacioná-los com a sorologia. Os resultados demonstraram que 0,43% (2/469) das amostras analisadas apresentaram anticorpos contra o agente. Esta região é caracterizada pelo clima semiárido e pela predominância do tipo de exploração extensiva, com presença de animais nativos, mestiços e sem raça definida para produção de carne e pele, com baixa produtividade e tecnificação.
