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...

Background: Bovine ephemeral fever virus (BEFV) is an arthropod-borne classified as a type species of the genus Ephemerovirus, family Rhabdoviridae. BEFV causative agent bovine (BEF), non-contagious disease acute febrile clinical signs in cattle and water buffalo. Some might act reservoir hosts, antibodies to have also been found asymptomatic sheep, goats, pigs, many wild animals. This study ai...

Our previous report demonstrated that bovine ephemeral fever virus (BEFV)-infected cultured cells could induce caspase-dependent apoptosis. This study aims to further elucidate how BEFV activates the caspase cascade in bovine cells. BEFV replicated and induced apoptosis in Vero and Madin-Darby bovine kidney (MDBK) cells, and a kinetic study showed a higher efficiency of replication and a greate...

The stability of some viruses and methods of virus inactivation in liquid manure are reviewed. The authors discuss experimental data on the stability of foot and mouth disease virus, classical swine fever virus, Aujeszky's disease virus, African swine fever virus, swine influenza virus, porcine paramyxovirus, bovine virus diarrhoea virus and transmissible gastroenteritis of pigs virus. Recommen...
