Overview of the typing and clinical features of Group C Streptococcus and Group G Streptococcus / 中华实用儿科临床杂志

ABSTRACT

Group C Streptococcus (GCS) and Group G Streptococcus (GGS) distinctly differ from other Streptococcus in biochemical reactions, hemolytic properties, host species, and clinical characteristics.GCS and GGS are common colonizers of the skin, throat and female genitourinary tract of human body.The classification of GCS and GGS is complex and has been continuously corrected and revised over the past few decades.The outbreak of GCS and GGS infections mostly likely arises from environmental factors.GCS and GGS have similar pathogenicity, bacterial resistance characteristics, and clinical characteristics to group A Streptococcus.They can lead to various invasive infections, and Penicillin is still the first choice for their treatment currently.GCS and GGS infections are more severe than other Streptococcus infections.In this article, the classification and clinical characteristics of GCS and GGS were reviewed.
