Group G Streptococcus strains isolated from patients with severe invasive infections in the period 2002–2008 were surveyed and their prevalence compared with that observed in the period 1995–2001 in Japan. Strains with genotypes stg485, stg6792, stc36, stg6, and stg652 were isolated in both periods, whereas various new genotypes appeared in 2002–2008 and some genotypes found in 1995–2001 were not found subsequently, thus indicating a change in the prevalent genotyped strains causing severe invasive streptococcal infections.
