Phylogenetic Relationships of the Partial G Gene Sequence of Bovine Ephemeral Fever Virus Isolated from Mainland China, Taiwan, Japan, Australia, Turkey and Israel

cloning and sequencing of g glycoprotein gene of bovine ephemeral fever virus in escherichia coli

introduction bovine ephemeral fever (bef) is an arthropod-borne viral disease of cattle and water buffalo, spanning tropical and subtropical zones in asia, australia, and africa continents. the clinical signs of bef disease in cattle are acute febrile reaction, stiffness, lameness, depression, cessation of rumination, and constipation. this disease was caused by ephemerovirus of the rhabdovirid...

Isolation of Bovine Ephemeral Fever Virus in Iran

DNA sequence analysis of glycoprotein G gene of bovine ephemeral fever virus and development of a double oil emulsion vaccine against bovine ephemeral fever.

The surface glycoprotein G is considered as the major neutralizing and protective antigen of bovine ephemeral fever virus (BEFV). Comparison of the deduced amino acid sequence of G protein of BEFV isolates during the period 1984-2004 outbreaks in Taiwan showed amino acid substitutions in the neutralizing epitopes. All the isolates differ markedly in the neutralizing epitope at the same amino ac...

Phylogenetic analysis of classical swine fever virus isolated from Taiwan.

By analyzing the E2 sequences of classical swine fever virus from field outbreaks in Taiwan during 1993-2001, three virus populations with distinct genotypes were determined including one historical (subgroup 3.4) and two exotic (subgroup 2.1) strains. The first subgroup 2.1 virus was isolated in 1994 and further sporadic outbreaks occurred after 1996. Phylogenetic analysis using the E2 region ...

Resurgence of bovine ephemeral fever in mainland Japan in 2015 after a 23-year absence

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...
