South African bovine ephemeral fever virus glycoprotein sequences are phylogenetically distinct from those from the rest of the world

摘要

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.
