Abstract
On February 16, and March 8, 1987, two abnormal cattle births occurred in Saga Prefecture. One displayed an inability to stand, crooking of the four extremities, and rachicampsis, while the other was stillbirth. From the histopathological findings and neutralizing test against Aino virus, it was suggested that the abnormal births may have been associated with an infection of Aino virus.
A survey of neutralizing tests against Aino virus revealed that this virus was widely prevalent among cattle in Saga Prefecture, and the epizootic of this virus infection started in September, as well as, that of the Akabane virus.
