A Large-Scale Outbreak of Bovine Ephemeral Fever in Turkey, 2012

A Large-Scale Outbreak of Bovine Ephemeral Fever in Turkey, 2012

Regional cases of bovine ephemeral fever (BEF) were documented previously in Turkey. Previous cases were confirmed in South-East Turkey with low cow mortality. Recent BEF-suspected outbreaks with high mortality were documented in many regions of Turkey in 2012. The aim of study was the epidemiological examination of the outbreak and molecular characterization of the viruses detected from the ou...

identification of bovine ephemeral fever (bef) outbreak in a large dairy farm in varamin, iran

bovine ephemeral fever (bef) flared up in a dairy farm with 2097 animals. the disease started in september, 2006, with daily means of environmental temperature (et) and relative humidity (rh) of 23.8 ºc and 37%, respectively, and ended after 48 days with et and rh of 16.2 ºc and 68%, respectively. in this outbreak, the age of affected animals was above 10 months and the morbidity rate was 13.07...

Isolation of Bovine Ephemeral Fever Virus in Iran

Occurrence of bovine ephemeral fever in Okinawa Prefecture, Japan, in 2012 and development of a reverse-transcription polymerase chain reaction assay to detect bovine ephemeral fever virus gene

In September 2012, several cows and a calf showed decreased activity, anorexia and fever on Ishigaki Island, Okinawa Prefecture, Japan, and the cases were diagnosed as bovine ephemeral fever (BEF). We isolated BEF virus (BEFV) from one of the affected cows and then determined the complete genome sequence of the G gene, which encodes a class I transmembrane glycoprotein of BEFV. The BEFV isolate...

Epidemiological analysis of bovine ephemeral fever in 2012-2013 in the subtropical islands of Japan.

BACKGROUND Bovine ephemeral fever (BEF) is a febrile disease of cattle that is transmitted by arthropod vectors such as mosquitoes and Culicoides biting midges. An outbreak of BEF recently occurred in Ishigaki Island and surrounding islands that are located southwest of Japan. In this study, an epidemiological analysis was conducted to understand the temporal and spatial characteristics of the ...
