Vector-borne arboviruses produce mild to severe symptoms in domestic animals. Bovine ephemeral fever (BEF), Akabane, Aino, and Chuzan virus have been primarily attributed to reproductive disorders or febrile diseases in cattle, and Japanese encephalitis virus (JEV) is mainly associated with reproductive failures in swine. We investigated antibody titers from domestic swine against four bovine a...

Bovine ephemeral fever (BEF) is an economically important viral vector-borne cattle disease. Several live-attenuated, inactivated and recombinant vaccines have been tested, demonstrating varying efficacy. However, to the best of our knowledge, duration of immunity conferred by an inactivated vaccine has never been reported. In the last decade, Israel has faced an increasing number of BEF outbre...

The nucleotide sequence of the bovine ephemeral fever virus (BEFV) genome has been determined from the 3' terminus to the end of the nucleoprotein (N) gene. The 3' leader sequence comprises 50 nucleotides and shares a common terminal three nucleotides (3'-UGC-) and a downstream U-rich domain with vesicular stomatitis virus (VSV) and rabies virus. The N gene comprises 1328 nucleotides from the t...

In September and October 2015, suspected cases of bovine ephemeral fever (BEF) were reported in the mainland region of Kagoshima Prefecture and on Tanegashima Island. The genome of the BEF virus (BEFV) was detected in the diseased cows and the cows that had recovered. The serum obtained from the affected cows contained high titers of BEFV-neutralizing antibody. In total, 18 affected cows were d...

Bovine ephemeral fever (BEF) virus is an arthropod-borne rhabdovirus and causing acute febrile illness disease in cattle water buffalo. Foot-and-mouth (FMD) a highly infectious viral of mammals has great potential for severe economic loss susceptible cloven-hoofed animals. FMD BEF vaccines are widely used countries where both diseases seen together. This study was carried out to determine the i...

Electron microscopic studies on ephemeral fever virus (EFV) have shown that the virus is cone-shaped having a basal diameter of approximately 176 m/k and a height of about 88 m/k (Lecatsas, Theodoridis & Erasmus, 1969). These workers have also shown that the virus has an envelope derived from the host cell membrane and that the internal electron-dense component consists of a spirally arranged m...

remarks on the other side of the question. Any one who has had the opportunity of watching the course of an epidemic of enteric fever at home and of treating groups of cases from the same street, perhaps from the same household, must have been struck by the great variation among the cases as regards severity and mildness, and varying predominance of symptoms. There seems to bs no reason why mil...
