G10 rotaviruses, which are usually found in cattle, have also been reported in neonatal infections in recent years. During the rotavirus surveillances of children less than 4years of age between 2003 and 2006 in Kolkata, eastern India, 60 out of 1153 samples could not be typed. All 60 samples gave usual electropherotype pattern in polyacrylamide gel. Thirty-one out of these 60 G and P untypable rotavirus strains were successfully characterized during the study. Among 31 samples, G9P[4] (n=8), G12P[8] (n=8), G1P[8] (n=6), G10P[4] (n=6), and G2P[4] (n=3) genotypes were identified. In this study we report genetic analysis of the six G10 strains, which revealed close relations with Turkish (E29TR) bovine strains, as well as with bovine-like-equine strain (Erv2) from India. SimPlot of the VP7 gene segment suggested possible recombination event between the bovine and the bovine-like-equine rotaviruses in these human rotavirus infections.
