Nucleotide sequence homology between bovine, simian, and porcine rotavirus was determined by the RNA:RNA hybridization technique. Single stranded RNA, prepared in vitro with EDTA activated endogeneous viral RNA polymerase, was hhbridized with tritium labeled bovine rotavirus genomic RNA. The heteroduplex RNA was treated with single stranded RNA specific ribonucleases and the RNase resistant hybrid RNA was precipitated, and collected by filtration on a filter paper. Seventy four percent RNA sequence homology between bovine and simian rotavirus and 8 percent RNA sequence homology between bovine and porcine rotavirus was confirmed by hybridization between tritium labeled single stranded RNA and viral genomic RNA.
