^bNorwalk, Hu/NV/GI/Norwalk/1968/US, GenBank accession no. M87661; Hawaii, Hu/NV/GII/Hawaii/1971/US, GenBank accession no. U07661; Houston/86, Hu/SV/Houston/1986/US, GenBank accession no. U65427; UK, bovine rotavirus strain, GenBank accession no. X55444; YM, porcine rotavirus strain, GenBank accession no. X76486; KU, human rotavirus strain, GenBank accession no. AB022765; SA11, simian rotavirus strain, GenBank accession no. X16830. The locations of the primers in the genome are based on the sequence of the full-length Norwalk genome and the complete sequence of UK VP1.

^c+, reactive by RT-PCR; −, nonreactive by RT-PCR; NT, not tested.
