a virus of the genus Bunyavirus, family Bunyaviridae, causing abortion in cattle and congenital arthrogryposis and hydranencephaly in bovine fetuses in Israel, Japan, and Australia; it is transmitted by mosquitoes.
Akabane virusAn arbovirus first identified in the Akabane district in Japan, which passes through the placenta of early embryos in cattle and causes congenital neurologic problems in calves.
Haematophagous midges (Culicoides brevitarsus).
a bunyavirus transmitted by insects, including Culicoides brevitarsis, and the cause of arthrogryposis and hydranencephaly, recognized in newborn calves and lambs following in utero infection in the early months of gestation.
Akabane virus disease
the causative bunyavirus is carried by insects, e.g. Culicoides brevitarsis, and affects only young fetuses in pregnant ruminants. At birth the calves are either without intelligence (imbecile calves) or have joint fixation, in flexion or extension, and create a dystocia (curly calves). See also aino virus disease, hydranencephaly. Called also enzootic bovine arthrogryposis.
