Abstract
Two-dimensional gel electrophoreses of RNase T1-derived oligonucleotides of the three individual RNA segments of the bunyavirus snowshow hare virus indicate that its three RNA segments possess distinct nucleotide sequences. The fingerprints of the RNA species of snowshoe hare virus differ from those of the antigenically closely related La Crosse virus. Three viral RNA species have been identified in preparations of Melao and Trivittatus as well as snowshoe hare, Lumbo, and La Crosse bunyaviruses.
