Ovine gammaherpesvirus-2 (OvHV-2) causes sheep-associated malignant catarrhal fever (SA-MCF) and is a fatal disease of some ruminants such as cattle, water buffalo and even-toed ungulates (such as deer, other cervids and some species of pigs). OvHV-2, however, was never reported to be present in the Philippines. Thus, this study is conducted. Out of 89 sheep blood samples from 6 farms, 58 (65.17 %) were positive for OvHV-2 using semi-Polymerase Chain Reaction targeting the tegument gene. Phylogenetic analysis suggests that the OvHV-2 sequences from sheep in the Philippines are nearly identical to the OvHV-2 sequences of animals from Brazil and Germany and 98 % identical to sequences from Turkey, India, Egypt, UK, and Mongolia. To date, this is the first report of OvHV-2 in the Philippines and could provide information in the future for the control and prevention of SA-MCF in the country.

绵羊γ疱疹病毒2（OvHV-2）会引起绵羊相关的恶性卡他热（SA-MCF），并且是一些反刍动物的致命疾病，例如牛，水牛和有趾的有蹄类动物（例如鹿，其他鹿和某些猪）。然而，从未有报道称OvHV-2在菲律宾存在。因此，进行了这项研究。在来自6个农场的89个绵羊血液样本中，有58个（65.17％）使用靶向tegument基因的半聚合酶链反应对OvHV-2呈阳性。系统发育分析表明，菲律宾绵羊的OvHV-2序列与巴西和德国动物的OvHV-2序列几乎相同，并且与土耳其，印度，埃及，英国和蒙古的序列相近98％。迄今为止，
