Key result
Recently emerging G9 VP7 genes in Japan were not direct descendants of 1980s prototype strains, but rather evolved independently into 4 phylogenetic clusters from a common ancestor.

Japanese children hospitalized with acute gastroenteritis from whom rotaviruses were recovered

Supports ongoing rotavirus genotype surveillance; leaves open effects on vaccine performance.
Recently emerging G9 VP7 rotavirus genes evolved independently into multiple phylogenetic clusters from a common ancestor rather than directly from prototype strains of the 1980s.
Oka et al. (2000) studied Acute Gastroenteritis. Serotype G9 rotavirus VP7 genes vs. Prototype G9 strains AU32 and F45 was evaluated on Phylogenetic relationship of VP7 genes. Recently emerging G9 VP7 genes in Japan were not direct descendants of 1980s prototype strains, but rather evolved independently into 4 phylogenetic clusters from a common ancestor.
