Infection of goats with caprine arthritis encephalitis virus (CAEV) has been detected in variable proportions in many countries all over the world. Here, we investigated the seroprevalence of CAEV in goats raised in Algeria.
A serological survey was performed on serum samples from 1,313 goats, including the local breeds (Arabia and Dwarf of Kabylia) and imported European breeds (Alpine and Saanen). Blood samples were taken from goats on 38 farms distributed across four different geographical regions of Algeria. Serum samples were tested for CAEV antibodies using a commercial ELISA.
A total of 390 serum samples were found to be positive for CAEV, giving an overall seropositivity rate of 29.7% in individual animals and 97.37% (37/38) at the goat farm level.
These results provide the first large-scale serological evidence for the presence of CAEV infection in both the local and imported breeds of goats raised in Algeria, indicating that the virus infection is widespread.
在世界许多国家，均检测到山羊感染山羊关节炎脑炎病毒（CAEV）的比例各不相同。在此，我们调查了阿尔及利亚饲养山羊中CAEV的血清流行率。
对1313只山羊的血清样本进行了血清学调查，这些山羊包括当地品种（阿拉伯山羊和卡比利亚矮山羊）以及引进的欧洲品种（阿尔卑斯山羊和萨能山羊）。从分布在阿尔及利亚四个不同地理区域的38个农场的山羊采集血样。使用商用酶联免疫吸附测定法（ELISA）检测血清样本中的CAEV抗体。
共发现390份血清样本CAEV呈阳性，个体动物的总体血清阳性率为29.7%，在山羊养殖场层面为97.37%（37/38）。
这些结果为阿尔及利亚饲养的当地和引进品种山羊中存在CAEV感染提供了首个大规模血清学证据，表明该病毒感染广泛存在。
