The G gene encoding the neutralization antigen of bovine ephemeral fever virus (BEFV) was characterized in order to define the virus's molecular epidemiology in Japan and the genetic relationships among the Japanese, Taiwanese and Australian isolates. The nucleotide and amino acid sequences of the gene were highly conserved among the Japanese strains,(More)
Two viruses were isolated from bovine blood in the southernmost part of Japan in 1994 and 2001, respectively. Genetic analyses showed that the viruses were Batai virus of the genus Orthobunyavirus of the family Bunyaviridae. The sequencing of three genomic RNA segments of the Japanese and Malaysian Batai virus strains revealed that the M RNA segment of(More)
BACKGROUND In Japan, epizootic arboviral infections have severely impacted the livestock industry for a long period. Akabane, Aino, Chuzan, bovine ephemeral fever and Ibaraki viruses have repeatedly caused epizootic abnormal births and febrile illness in the cattle population. In addition, Peaton, Sathuperi, Shamonda and D'Aguilar viruses and epizootic(More)
