Conteúdo: | This article describes the clinical, pathological and epidemiological aspects of 17 outbreaks of bluetongue (BT) disease in sheep occurring between December 2014 and July 2015 in the central region of Rio Grande do Sul state (RS), southern Brazil. Affected farms were visited for clinical examination, necropsy, sample collection and epidemiological investigation. The outbreaks were seasonal and occurred during the summer and autumn. A total of 180 sheep (20.4%) out of 884 in 17 small herds were affected. All ages of Texel and mixed breed sheep were affected. However, lambs (younger than one year) had higher morbidity than adult sheep. The most frequent clinical signs were anorexia, lethargy, loss of body condition, facial swelling mainly involving the lips, and greenish seromucous or mucous nasal discharge. Pulmonary lesions characterized by edema were the most prevalent findings; however, erosive and ulcerative lesions in the upper gastrointestinal tract, as well as cardiac, skeletal muscle and esophageal striated muscle necrosis, and hemorrhage in the pulmonary artery were also frequent. The bluetongue virus (BTV) genome was detected by RT-PCR in blood and tissue samples (spleen and lungs) of 21 animals from 17 outbreaks. The virus involved in the outbreak 3 was subsequently isolated and shown to belong to serotype 17, for the first time reported in Brazil. In summary, our data support the BTV genotype 17 as the etiological agent of the outbreaks and indicate that the central region of RS is an area at risk for BT in sheep, a disease previously not recognized in the region.
