Group A streptococcal infections are a number of infections with Streptococcus pyogenes, a group A streptococcus (GAS). [ 1 ]S. pyogenes is a species of beta-hemolytic Gram-positive bacteria that is responsible for a wide range of infections that are mostly common and fairly mild. If the bacteria enters the bloodstream, the infection can become ...
S. pyogenes is the predominant species harboring the Lancefield group A antigen, and is often called group A Streptococcus (GAS). However, both Streptococcus dysgalactiae and the Streptococcus anginosus group can possess group A antigen as well. Group A streptococci, when grown on blood agar, typically produce small (2–3 mm) zones of beta ...
Streptococcal pharyngitis, also known as streptococcal sore throat (strep throat), is pharyngitis (an infection of the pharynx, the back of the throat) caused by Streptococcus pyogenes, a gram-positive, group A streptococcus. [10][11] Common symptoms include fever, sore throat, red tonsils, and enlarged lymph nodes in the front of the neck.
Typically good [1] Scarlet fever, also known as scarlatina, is an infectious disease caused by Streptococcus pyogenes, a Group A streptococcus (GAS). [3] It most commonly affects children between five and 15 years of age. [1] The signs and symptoms include a sore throat, fever, headache, swollen lymph nodes, and a characteristic rash. [1]
Lancefield grouping. Lancefield grouping is a system of classification that classifies catalase -negative Gram-positive cocci based on the carbohydrate composition of bacterial antigens found on their cell walls. [1] The system, created by Rebecca Lancefield, was historically used to organize the various members of the family Streptococcaceae ...
M protein is strongly anti-phagocytic and is the major virulence factor for group A streptococci (Streptococcus pyogenes). It binds to serum factor H, destroying C3-convertase and preventing opsonization by C3b. However plasma B cells can generate antibodies against M protein which will help in opsonization and further the destruction of the ...
Group A S. pyogenes is the causative agent in a wide range of group A streptococcal infections (GAS). These infections may be noninvasive or invasive. The noninvasive infections tend to be more common and less severe.
78012-2. The rapid strep test (RST) is a rapid antigen detection test (RADT) that is widely used in clinics to assist in the diagnosis of bacterial pharyngitis caused by group A streptococci (GAS), sometimes termed strep throat. There are currently several types of rapid strep test in use, each employing a distinct technology.
