Thermal and pH stability of ephemeral fever virus (EFV) were studied. Infectivity of EFV was inactivated within 10 minutes at 56°C, by 18 hours at 37°C, and within 120 hours at 25°C. Infected mouse-brain virus had little titer loss after 30 days' storage at 4°C. Infected culture fluids stored at −35°C lost about 0.04 log units of virus per day. EFV was

Studies on Bovine ephemeral fever
2016A study of bovine ephemeral fever (BEF) virus was carried out using cell cultures, laboratory animals and cattle. Initially the virus strains studied were the BB7721 mouseadapted strain supplied by Dr R. L. Doherty, Queensland Institute of Medical Research; a bovine-adapted virus designated 70B/5 supplied by Mr I.

Neurotropic Strains of Bovine Ephemeral Fever Virus
Zentralblatt für Veterinärmedizin Reihe B, 2010Strains of bovine ephemeral fever (BEF) virus that were pathogenic for adult mice on intracerebral inoculation were derived after 7 or 8 serial intracerebral passages in suckling mice. The neurotropic strains produced tremors, convulsions, paralysis and death in adult mice in 4 to 6 days.

Apoptosis induced by bovine ephemeral fever virus
Journal of Virological Methods, 2004The potential significance of bovine ephemeral fever virus (BEFV)-induced apoptosis and involved viral molecules was fully unknown. In the present study, evidence is provided demonstrating that bovine ephemeral fever virus induces apoptosis in several cell lines. Five types of assays for apoptosis were used in examining BEFV-infected cells.

Bovine Ephemeral Fever in Australia and the World
2005Bovine ephemeral fever (BEF) is a disabling viral disease of cattle and water buffaloes. It can cause significant economic impact through reduced milk production in dairy herds, loss of condition in beef cattle and loss of draught animals at the time of harvest. Available evidence indicates clinical signs of BEF, which include bi-phasic fever, anorexia,

Bovine Ephemeral Fever Virus Vaccines in Mice
Zentralblatt für Veterinärmedizin Reihe B, 2010Adult mice were vaccinated with experimental bovine ephemeral fever virus vaccines, prepared from infected suckling mouse brain or infected Vero cell cultures, and challenged by intracerebral inoculation with a neurotropic strain of bovine ephemeral fever virus.

Preliminary observations on the epidemiology of bovine ephemeral fever in China
Tropical Animal Health and Production, 1991Bovine ephemeral fever (BEF) is a viral disease of cattle and water buffalo recognised for the first time in China in 1955. The disease has been endemic in south China with 13 epidemics since 1955, seven epidemics reaching central China and one extending into north-east China (40 degrees N).

Akabane and bovine ephemeral fever virus infections
Veterinary Clinics of North America: Food Animal Practice, 2002Akabane and bovine ephemeral fever viruses are exotic to the American continent. Both viruses are spread by insect vectors, and each causes disease of varying severity in food-producing animals. However, there are few other similarities between the agents and the diseases that they cause.

A CELL CULTURE VACCINE AGAINST BOVINE EPHEMERAL FEVER
Australian Veterinary Journal, 1978SUMMARY A vaccine was prepared from cell culture fluids harvested from the twelfth passage of the 919 strain of bovine ephemeral fever (BEF) virus in Vero cell cultures. Cattle were vaccinated subcutaneously with various combinations of strain 919 virus and adjuvants.
