Rapidly test for Streptococcus pyogenes (Group A β-hemolytic Streptococcus, Strep A) in throat swab specimens in point-of-care* settings.

The group A β-hemolytic Streptococcus is the most common bacterial pathogen associated with tonsillopharyngitis and is the only member of the group that can initiate ARF. Several cellular components and extracellular products produced by this streptococcus in vivo and in vitro have been identified. Group A beta-hemolytic streptococcal infections Pediatr Rev. 1998 Sep;19(9):291-302. doi: 10.1542/pir.19-9-291. Author M E Pichichero 1 Affiliation In addition, group A Streptococcus strains are beta-hemolytic (beta-hemolytic means the bacteria lyse red blood cells suspended in agar plates with secreted substances, see for example, Fig. 3). These tests are mentioned because they are frequently used to distinguish group A Streptococcus bacteria from group B, group C, and other Streptococcus Infection with Streptococcus pyogenes, a beta-hemolytic bacterium that belongs to Lancefield serogroup A, also known as the group A streptococci (GAS), causes a wide variety of diseases in humans. A ubiquitous organism, S pyogenes is the most common bacterial cause of acute pharyngitis , accounting for 15-30% of cases in children and 5-10% of Group A beta-hemolytic streptococcus (GABHS), the most common bacterial etiology, accounts for 15 to 30 percent of cases of acute pharyngitis in children and 5 to 20 percent in adults.2 Among SUMMARY Group A streptococci are model extracellular gram-positive pathogens responsible for pharyngitis, impetigo, rheumatic fever, and acute glomerulonephritis.

Group A beta-hemolytic streptococci (GAS) are known for causing pharyngitis and its sequelae, including acute rheumatic fever and post streptococcal glomerulonephritis. They also cause skin infections and invasive disease. Of all the streptococci, GAS are the most pathogenic for humans.

emm (M protein) gene sequencing has Streptococcus pneumoniae (a major cause of human pneumonia) and Streptococcus mutans and other so-called viridans streptococci (among the causes of dental caries) do not possess group antigens. Three types of hemolysis reaction (alpha, beta, gamma) are seen after growth of streptococci on sheep blood agar. Group A Streptococcus (GAS) is a bacteria that is normally found in the nose and throat of 10% of children and 1% of adults, without causing illness. When they do cause illness, the resulting disease is classified into one of two categories: Invasive or Non-invasive. What is the difference between Invasive and Non-invasive GAS? What is Strep B? Strep B or group B streptococci is referred to Streptococcus agalactiae. It is a beta hemolytic bacterium that is nonmotile and gram-positive.

Group A streptococci (GAS) are defined gram-positive spherical-shaped bacteria that produce beta- hemolysis (lysis of red blood cells producing clear or transparent areas in special growth media) and appear usually as a chain of two or more bacteria and have molecules on their surface known as Lancefield group A antigens. Group A streptococci when grown on blood agar typically produces small zones of beta-hemolysis, a complete destruction of red blood cells. (A zone size of 2–3 mm is typical.) It is thus also called group A (beta-hemolytic) Streptococcus ( GABHS ), and it can make colonies greater than 5 mm in size. Examples: Streptococcus pyogenes, or Group A beta-hemolytic Strep (GAS). Weakly beta-hemolytic species: Streptococcus agalactiae, Clostridium perfringens, Listeria monocytogenes. Alpha-hemolytic Streptococci. Alpha-hemolysis (α-hemolysis) is a partial or “green” hemolysis associated with reduction of red cell hemoglobin.
