Abstract

A virus isolated from one of the blood samples collected from sentinel cattle in late summer of 1999, at Omura (32.59 N, 129.58 E), in Nagasaki Prefecture was identified by the cross-neutralization test as the Peaton virus, which belongs to genus Bunyavirus of the family Bunyaviridae. This virus was first isolated in Australia in 1976. The nucleotide identity of the nucleocapsid protein encoded by the S segment in the present virus differed by 8.9% from that of the Australian virus. But the amino acids of both viruses were nearly (98.7%) identical. A serological survey of the sentinel cattle showed that the virus spread during late summer-between August and November. Seroconversion to the virus was reached in 38.0% of the cattle in November 1999. Retrospective surveillance data indicated that the epidemic of the virus occurred intermittently for several years (1985, 1987, and 1995) during the last 15 years.
