Bovine ephemeral fever virus (BEFV) is an economically important arbovirus affecting cattle and water buffalo. Currently, isolates can be separated into three phylogenetic groups, differentiated by the place of isolation, namely, East Asia, Australia, and the Middle East. BEFV surface glycoprotein (G) genes from 14 South African field strains collected between 1968 and 1999 were sequenced and compared to 154 published sequences. The BEFV isolates from South Africa were found to be phylogenetically distinct from those from other parts of the world.

南非牛短暂性发热病毒糖蛋白序列在系统发育上与世界其他地区不同。

牛短暂性狂热病毒（BEFV）是一种经济上重要的虫媒病毒，会影响牛和水牛。当前，分离株可分为三个系统发育组，按分离位置区分，即东亚，澳大利亚和中东。对1968年至1999年间收集的14种南非田间菌株的BEFV表面糖蛋白（G）基因进行了测序，并与154种公开序列进行了比较。发现来自南非的BEFV分离株在系统发育上与来自世界其他地区的分离。
