Complete genome sequence of three Streptococcus species

We determined complete genome sequence of three Streptococcus species, S. pyogenes, S. suis, and S. dysgalactiae. Among these three species, S. pyogenes and S. dysagalactiae have recognized as causative agents occasionally causing sever disease (ex. toxic shock syndrome) to human. On the other hand, S. suis is one of the major zoonotic agent and cause a variety of infections in individuals working in close contact with swine or pork products. In this study, we focus on the gene sets or genomic regions contributing to their pathogenicity, based on the complete genome sequence of three Streptococcus species.
