Why Is the Study of Group A Streptococcal Infections a Priority for NIAID? Group A streptococcus (GAS) is a rare but serious cause of postpartum and gynecological infections. There are no follow-up or prophylaxis guidelines for women with previous GAS genital infection. We aimed to evaluate the incidence of long-term gynecological carrier state in patients with a history of genital GAS infection. Group A streptococcus (GAS) bacteria is a Gram positive, beta-hemolytic coccus in chains. It is responsible for a range of diseases in humans. These diseases include strep throat (acute pharyngitis) and skin and soft tissue infections such impetigo and cellulitis.

Group A  Jan 8, 2019 Group A Streptococcus (GAS, Streptococcus pyogenes) is responsible for a wide range of acute and chronic clinical manifestations in humans. Streptococcus pyogenes (group A streptococcus / GAS) is a beta hemolytic gram positive cocci. There are over 130 serotypes.

Group A Streptococcus (group A strep, Streptococcus pyogenes) can cause both noninvasive and invasive disease, as well as nonsuppurative sequelae. Learn more about the etiology, clinical features, diagnosis and treatment options, prognosis and complications, and prevention of some of these infections below.
