Abstract

Bluetongue (BT) is an arthropod-borne viral disease that primarily affects ruminants in tropical and temperate regions. In the present study, a cross-sectional survey was conducted to define the seroprevalence of Bluetongue virus and to identify the possible risk factors correlated with BTV seropositivity among cattle, sheep, and goats during the period 2015-2016 in Gadarif State. A total of 420 cattle, 877 sheep, and 641 goat serum samples were collected randomly from 12 localities. Information about age, sex, breed, area ecology, and location was obtained for each sample. Bluetongue seroprevalence was estimated using competitive enzyme-linked immunosorbent assay (cELISA). The overall seroprevalence of BTV was 92.9% (390/420), 76.4% (670/877), and 85.3% (547/641) among cattle, sheep, and goats, respectively. Multivariate analysis followed univariate analysis showed that there was a significant difference (p < 0.05) between location, area ecology and age groups of cattle, sheep, and goats, and seropositivity to BTV. In addition, a significant association (p < 0.05) was observed between sex and seropositivity to BTV in sheep. In conclusion, BTV antibodies are highly prevalent in Gadarif State and susceptible livestock are at risk of exposition with BTV. Consequently, these animals have protection against specific BTV serotypes.

苏丹东部加达里夫州牛、绵羊和山羊蓝舌病病毒 (BTV) 血清流行病学调查。

蓝舌病（BT）是一种节肢动物传播的病毒性疾病，主要影响热带和温带地区的反刍动物。在本研究中，我们进行了一项横断面调查，以确定蓝舌病病毒的血清流行率，并找出 2015-2016 年期间加达里夫州牛、绵羊和山羊中与蓝舌病病毒血清阳性相关的可能风险因素。共从 12 个地方随机采集了 420 头牛、877 只绵羊和 641 只山羊的血清样本。每个样本都获得了有关年龄、性别、品种、地区生态和地点的信息。采用竞争性酶联免疫吸附试验（cELISA）估算蓝舌病血清流行率。牛、绵羊和山羊的蓝耳病总血清流行率分别为 92.9%（390/420）、76.4%（670/877）和 85.3%（547/641）。单变量分析后的多变量分析表明，牛、绵羊和山羊的地点、地区生态和年龄组与 BTV 血清阳性率之间存在显著差异（p < 0.05）。此外，性别与绵羊的 BTV 血清阳性率之间也有明显关联（p < 0.05）。总之，BTV 抗体在加达里夫州非常普遍，易感牲畜有感染 BTV 的风险。因此，这些牲畜对特定的 BTV 血清型具有保护作用。
