Sheep-associated malignant catarrhal fever (SA-MCF), caused by ovine gammaherpesvirus-2 (OvHV-2), is a fatal disease in all ruminants. The epidemiological survey and molecular characterization of OvHV-2 in Mongolian livestock were performed. Of 928 blood samples, 14 were positive for OvHV-2 in sheep and native cattle from Tsenkher County and in sheep from Lun County. Phylogenetic analyses revealed that the tegument gene of OvHV-2 sequences from Mongolian animals is identical to that in animals from Egypt, India, and Turkey, and is 98.0% similar to that in animals from Germany and Brazil. To our knowledge, this is the first confirmed report of OvHV-2 in Mongolian livestock, and could provide useful information for controlling SA-MCF.
绵羊相关的恶性卡他热（SA-MCF）由绵羊γ疱疹病毒2型（OvHV-2）引起，是所有反刍动物的一种致命疾病。对蒙古家畜中的OvHV-2进行了流行病学调查和分子特征分析。在928份血样中，来自森赫县的绵羊和本地牛以及伦县的绵羊中有14份OvHV-2呈阳性。系统发育分析表明，蒙古动物的OvHV-2序列的被膜基因与埃及、印度和土耳其动物的相同，与德国和巴西动物的相似性为98.0%。据我们所知，这是蒙古家畜中首次确诊的OvHV-2报告，可为控制SA-MCF提供有用信息。
