Identification of bovine and porcine rotavirus G types by PCR.

A new seminested PCR typing assay has been extended to identify the important veterinary rotavirus serotypes G5, G6, G10, and G11, as well as the rare human serotype G8. The specificity of the method was evaluated with 30 standard laboratory strains of the G1 to G6 and G8 to G11 types. Rotavirus strain types G6 and G8, not previously recognized in pigs, were identified in field specimens of porcine origin.
