Evidence for independent segregation of the VP6- and NSP4- encoding genes in porcine group A rotavirus G6P[13] strains.
Molecular characterization of two porcine group A rotavirus strains (HP113 and HP140), detected from eastern India, revealed a VP7 closely related to those of human G6P[14] strains, VP4 with a borderline P[13] genotype, and VP6 related to bovine and human SGI strains rather than porcine SGI and/or SGII group A rotaviruses. Both strains had NSP4 and NSP5 of porcine origin. Therefore, to our knowledge, the present study is the first report of detection of group A rotavirus strains with G6P[13] genotype specificities and provides evidence for independent segregation of the VP6- and NSP4-encoding genes in porcine group A rotaviruses.
