Molecular characterization of VP4, VP6, VP7, NSP4, and NSP5/6 genes identifies an unusual G3P[10] human rotavirus strain
An unusual strain of human rotavirus G3P[10] (CMH079/05) was detected in a stool sample of a 2-year-old child admitted to the hospital with severe diarrhea in Chiang Mai, Thailand.

An unusual strain of human rotavirus G3P[10] (CMH079/05) was detected in a stool sample of a 2-year-old child admitted to the hospital with severe diarrhea in Chiang Mai, Thailand. Analysis of the VP7 gene sequence revealed highest identities with unusual human rotavirus G3 strain CMH222 at 98.7% on the nucleotide and 99.6% on the amino acid levels. Phylogenetic analysis of the VP7 sequence confirmed that the CMH079/05 strain formed a cluster with G3 rotavirus reference strains and showed the closest lineage with the CMH222 strain.
