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.
对 2002-2008 年期间从严重侵袭性感染患者中分离到的 G 组链球菌菌株进行了调查,并与日本 1995-2001 年期间的流行情况进行了比较。在两个时期都分离到了 stg485、stg6792、stc36、stg6 和 stg652 基因型的菌株,而 2002-2008 年期间出现了各种新的基因型,而 1995-2001 年期间发现的一些基因型随后则未再发现,表明引起严重侵袭性链球菌感染的流行基因型菌株发生了变化。
