Cloning of Full Genome and Genotyping of a Group A Human Rotavirus / 中国生物工程杂志

By means of genetic cloning and recombinant techniques, full genome cDNA sequences of rotavirus strain TB-Chen were isolated from an infantile hospitalized with acute gastroenteritis. Nucleotide sequences analyses showed that the full genome of strain TB-Chen contains 18613 nucleotides, encoding 5791 amino acids. Genotyping results showed that the strain TB-Chen belongs to genotype G2P[4]/NSp4[A]. This is the first report on a full genome of Group A rotavirus in China, and has important significance for deep understanding structure and functions of rotaviruses and developing rotavirus vaccines.
