Molecular characterization of unusual bovine group A rotavirus G8P[14] strains identified in western India: emergence of P[14] genotype.

A total of 78 fecal specimens were collected from both apparently healthy (n=71) and diarrheic (n=7) cattle from an organized farm in Pune, western India in December 2007-January 2008. Three specimens tested positive for group A rotavirus (RV) by antigen capture ELISA were subjected to RT-PCR for amplification of entire coding regions of three structural (VP4, VP6 and VP7) and one nonstructural (NSP4) genes. All three strains were genotyped as G8P[14].
