The objective of this study was to describe the seroprevalence rates of bluetongue virus (BTV) in sheep in west and northwest provinces of Iran. Bluetongue virus, an economically important orbivirus of the Reoviridae family, causes a hemorrhagic disease mainly in sheep and occasionally in cattle and some species of deer. Bluetongue virus is transmitted between its mammalian hosts by certain species of biting midges (Culicoides spp.) and it can infect all ruminant species. Overall, 26 serotypes have been reported around the world. Due to its economic impact, bluetongue (BT) is an Office of International des Epizooties (OIE)-listed disease. A total of 756 sera samples collected during 2007-2008, were available. Sera were tested with competitive enzyme-linked immunosorbent assay (C-ELISA). The seroprevalence rate in sheep was 40.87%. The rate of positivity in sheep in west and northwest was 46.10% and 33.75%, respectively. The highest prevalence of antibodies in serum was in West Azerbaijan (64.86%), and lower was in Ardabil (23.77%).
本研究的目的是描述伊朗西部和西北部省份绵羊中蓝舌病毒（BTV）的血清流行率。蓝舌病毒是呼肠孤病毒科一种具有重要经济意义的环状病毒，主要引起绵羊的出血性疾病，偶尔也会感染牛和某些鹿种。蓝舌病毒通过某些种类的吸血蠓（库蠓属）在其哺乳动物宿主之间传播，并且它可以感染所有反刍动物物种。总体而言，全世界已报道了26种血清型。由于其经济影响，蓝舌病（BT）是国际兽疫局（OIE）列出的疾病。共有2007年至2008年期间采集的756份血清样本可供检测。血清用竞争酶联免疫吸附测定（C-ELISA）进行检测。绵羊的血清流行率为40.87%。西部和西北部绵羊的阳性率分别为46.10%和33.75%。血清中抗体流行率最高的是西阿塞拜疆（64.86%），较低的是阿尔达比勒（23.77%）。
