Isolation and characterization of Sedlec virus, a new bunyavirus from birds.

A pathogenic agent designated AV 172 was isolated from the blood of a Reed Warbler (Acrocephalus scirpaceus) out of 767 samples from birds belonging to 35 species and 14 families. The birds (largely wetland passerines) were captured in the reed-belt littoral of Nesyt fishpond in southern Moravia, Czechoslovakia, during the years 1984 to 1987. Virus AV 172 has been found to represent probably a new species (designated virus "Sedlec") of family Bunyaviridae.
