A Report on Bovine Ephemeral Fever Virus in Turkey: Antigenic Variations of Different Strains of EFV in the 1985 and 2012 Outbreaks Using Partial Glycoprotein Gene Sequences.

We described the aetiological agents of outbreaks of bovine ephemeral fever ( BEF) that occurred in 1985 and 2012 in Turkey, and identify mutations in the viruses from both outbreaks. Outbreaks have emerged periodically every 4-5 years in the same regions in Turkey. Because these regions are located in a subtropical climatic zone, good conditions for vector populations exist. The results of this study show that the BEFVs from outbreaks in Turkey vary significantly. Effective prevention will require a vaccine that contains BEFVs from different genetic clusters.
