title: Genetically diverse group C rotaviruses cause sporadic infection in Korean calves.
abstract: This study examined the prevalence and genetic diversity of the bovine group C rotaviruses (GCRVs) in a total of 127 diarrhea fecal samples of calves from 52 Korean native beef calf herds using RT-PCR and nested PCR. Overall, seven of the 127 fecal samples (5.5%) from seven of the 52 herds (13.5%) tested positive for bovine GCRVs only by nested PCR. Sequence and phylogenetic analyses of a partial VP6 gene showed that Korean bovine GCRVs had marked genetic diversity; two Korean strains belonged to the bovine lineage, whereas five Korean strains belonged to the porcine lineage. These results suggest that the genetically diverse bovine GCRVs cause sporadic infections in diarrheic calves in South Korea.
