Maedi-visna (MV) is a chronic viral disease prevalent in adult sheep that is caused by a virus belonging to the small ruminant lentivirus group (SRLV). This disease is considered to affect the international trade of sheep and is classified in the World Organisation for Animal Health (OIE) list of notifiable animal diseases. Although maedi-visna virus (MVV) has been detected in many countries, no study on its occurrence has been carried out in Lebanon. For this purpose, a serological survey of infection with MVV was conducted in seven of the eight Lebanese governorates using a competitive enzyme-linked immunosorbent assay (ELISA). A total of 184 individual blood samples from sheep of the local breed 'Awassi', originating from 16 farms distributed throughout the seven Lebanese governorates, were collected and analysed. Among the 184 tested sheep, 131 sheep from the16 farms visited were MVV positive. This presents a prevalence of 71% MVV-positive animals and 100% MVV-positive farms. The results indicate the need for further systematic investigations into the between-herd and within-herd prevalence of MV in Lebanon.
梅迪-维斯纳病（MV）是一种在成年绵羊中流行的慢性病毒性疾病，由属于小反刍兽慢病毒组（SRLV）的病毒引起。这种疾病被认为会影响绵羊的国际贸易，并被列入世界动物卫生组织（OIE）的法定动物疫病清单。尽管在许多国家都检测到了梅迪-维斯纳病毒（MVV），但黎巴嫩尚未开展关于其发生情况的研究。为此，使用竞争酶联免疫吸附测定（ELISA）对黎巴嫩八个省份中的七个省份进行了MVV感染的血清学调查。共采集并分析了来自黎巴嫩七个省份16个农场的本地品种“阿瓦西”绵羊的184份个体血样。在184只受试绵羊中，来自所走访的16个农场的131只绵羊MVV呈阳性。这表明MVV阳性动物的患病率为71%，MVV阳性农场的患病率为100%。结果表明有必要对黎巴嫩羊群间和群内MV的流行情况进行进一步的系统调查。
