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.
- A. v. 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.
