Abstract

Group C rotaviruses are an important cause of acute gastroenteritis in humans and animals. Fecal samples were collected from a porcine herd in July, 2009. Group C rotavirus RNA was detected using RT-PCR for the VP6 gene. The identified strain was further characterized by sequencing and phylogenetic analysis of the partial VP4, and complete VP6 and VP7 gene sequences. The partial VP4 and complete VP6 gene sequences of the CUK-5 strain were most closely related to those of the CUK-6 strain of group C rotaviruses. Phylogenetic analysis of the VP7 gene of the 2 strains (CUK-5 and CUK-6) and reference strains of group G rotavirus by the neighbor-joining method also confirmed that CUK-5 and CUK-6 belonged to type G5 and G1 strains, respectively. This study provides useful data for the prediction of newly appearing variants of porcine group C rotaviruses in neighboring countries through comparisons with GCRVs and fundamental research for vaccine development.
