title: Prevalence of antibodies against Parainfluenza virus type 3, Respiratory syncitial virus and bovine Herpesvirus type 1 in sheep from Northern Prefectures of Japan.
abstract: Ovine sera collected in the Prefectures of Hokkaido, Aomori and Iwate in the Northern Japan were examined for the presence of antibodies against Respiratory syncytial virus (RSV), bovine Herpesvirus type 1 (infectious bovine rhinotracheitis: IBR) and Parainfluenza virus type 3 (PIV3) using serum neutralisation (SN) and enzyme-linked immunosorbent assay (ELISA) tests. Twenty-three animals (11.73%) out of the 196 tested were sero-positive to PIV3. Sixteen animals (8.69%) out of the 184 tested reacted to RSV. No animals were positive to IBR antigen. Sero-conversions to PIV3 were detected in Hokkaido and Iwate (14.92% and 8.82%, respectively). Antibodies against RSV were detected in Hokkaido (9.23%) and Aomori (14.28%). Although no diagnostic measures were in place, the infections did not appear to be related to any reduction in sheep productivity.
