Beta-hemolytic streptococci (esp. Streptococcus pyogenes) that produce human diseases, including pharyngitis, cellulitis, erysipelas, impetigo, otitis media, pneumonia, scarlet fever, necrotizing fasciitis, sepsis, sinusitis, and tonsillitis.In addition, group A streptococcus infection may have immunologic sequelae such as rheumatic fever and acute glomerulonephritis.

Learn more below about some of these infections, including symptoms, risk factors, treatment options, and how to prevent them. They belong to group A in the Lancefield classification system for β-hemolytic Streptococcus, and thus are also called group A streptococci. Figure 1.

Infected children should be kept away from school, pre-school or childcare until they have received at least 24 hours of antibiotic treatment and feel well. Although headache is not one of the Centor criteria, it is a commonly looked for symptom of strep throat and is associated with group A streptococcal infection in both children and adults. 11,12 The bacteria most likely to cause strep throat and bacterial sore throats in general are called Group A beta-hemolytic Streptococcus pyogenes (GABHS). This test is a highly reliable way to diagnose strep throat because it has a sensitivity of 90% to 95%.

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.

Streptococci are gram-positive aerobic organisms that cause many disorders, including pharyngitis, pneumonia, wound and skin infections, sepsis, and endocarditis. Symptoms vary with the organ infected. Sequelae of infections due to group A beta-hemolytic streptococci may include rheumatic fever and glomerulonephritis.
