Bovine Ephemeral fever virus (BEFV) is endemic in South Africa and has a negative economic impact on the meat and dairy industries. Bovine ephemeral fever or three-day stiff-sickness is controlled through annual vaccination with a live attenuated virus manufactured by Onderstepoort Biological Products (South Africa). We announce the genome sequences of two South African Bovine Ephemeral Virus strains; the live attenuated vaccine strain (14 876 nucleotides) and a field strain (14 883 nucleotides). A mutation in the alpha 3 open reading frame rendered the gene non-functional in both genomes. Phylogenetic analysis based on the glycoprotein gene showed that the two strains clustered with the South African lineage.
牛暂时热病毒(BEFV)在南非流行,对肉类和奶制品行业造成了负面影响。通过使用由 Onderstepoort 生物制品(南非)生产的减毒活疫苗对牛进行年度接种,可以控制牛暂时热或三天僵病。我们宣布了两个南非牛暂时热病毒株的基因组序列;减毒活疫苗株(14876 个核苷酸)和田间株(14883 个核苷酸)。α3 开放阅读框中的突变使两个基因组中的基因失去功能。基于糖蛋白基因的系统发育分析表明,这两个菌株与南非谱系聚类。
