Genome sequences of the 15 bluetongue virus vaccine strains incorporated in the South African live-attenuated vaccine.

Bluetongue disease in endemic areas is predominantly controlled through vaccination with live-attenuated vaccines. Sequencing of the original master seed viruses used in the production of Onderstepoort Biological Products vaccine was conducted. Nucleotide identities of 82.

Genome sequence of Bovine Ephemeral fever virus vaccine strain of South African origin.

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).
