The Group G Streptococcus (beta-hemolytic) is a type of bacteria that belongs to the Streptococcus genus. This type of bacteria is usually found on the skin and in the respiratory tract of humans. Nevertheless, it can cause various types of infections. The name "beta-hemolytic" is associated with their ability to break down red blood cells, which results in the formation of a clear zone around bacterial colonies when they are cultured on blood agar. Infections with Group G Streptococcus are usually less common than infections with Group A or B Streptococcus, but they can still be serious. Streptococcal infections are treated with antibiotics.
