Abstract

1986~1995年に兵庫県下で発生した牛異常産例についてアカバネウイルスおよびアイノウイルスの分離と抗体調査を行った. アカバネウイルスの流行は1986, 1987, 1990, 1991および1994年に県の南部および中部でみられ, 1994年には流行地域で水無脳症をともなう14頭の病例が発生した. アイノウイルスの流行は1994年を除き毎年みられ, 1995年には2例のおとり牛の血液からウイルスが分離された. 流行地域では水無脳症, 小脳形成不全および脊柱弯曲をともなう異常産発生がみられ, 初乳未摂取異常子牛が抗アイノウイルス抗体のみを保有していた.

The prevalence of Akabane and Aino viruses in bovine cases of congenital abnormalities was investigated from 1986 through 1995 in Hyogo Prefecture. Antibody against Akabane virus was detected in 1986, 1987, 1990, 1991 and 1994 mainly in the southern area, where 14 cases were pathologically and serologicaly diagnosed as congenital arthrogryposis-hydranencephaly (AH) syndrome from November 1994 through June 1995. Antibody to Aino virus was detected every year from 1986 to 1995 except for 1994 and two epizootics of congenital deformities were observed only in the southern area. The second epizootic of congenital abnormalities occurred in 28 calves from October 1995 through April 1996, and many of affected calves showed pathological findings of AH syndorome, including cerebellar hypoplasia. The precolostrum sera from 5 calves with AH syndrome were positive for neutralizing antibodies to Aino virus, suggesting that the epizootics was due to Aino virus.
