- Strep is short for Streptococcus, a type of bacteria. There are two types: group A and group B. Group A strep causes. 1  Strep throat-a sore, red throat, sometimes with white spots on the tonsils. 2  Scarlet fever-an illness that follows strep throat. 3  It causes a red rash on the body.

- Group A streptococcus (GAS) — The most important treatable agent is group A streptococcus (GAS). Approximately 5 to 15 percent of sore throats in adults yield positive cultures for GAS [2]. Clinical features of GAS include the sudden onset of sore throat, tonsillar exudate, tender cervical adenitis, and fever.

- Group A and group B streptococci are beta hemolytic, whilst D are usually alpha or gamma. Streptococcus pneumoniae and viridans (green) streptococci are alpha hemolytic. Thus, the hemolysis reaction is important in grouping streptococci.

Group A Streptococcus: Commonly Asked Questions Download a PDF version formatted for print: Group A Streptococcus: Commonly Asked Questions (PDF: 60KB/2 pages) What is Group A Streptococcus (GAS)? Group A streptococci are bacteria commonly found in the throat and on the skin. People may carry GAS in the throat or on the skin and not become ill. How are Group A Streptococci Spread? These bacteria are spread by direct contact with discharges from the nose and throat of infected people or by contact with infected wounds or sores on the skin.

- Streptococcus agalactiae is the species designation for streptococci belonging to the group B of the Rebecca Lancefield classification.GBS is encapsulated by a capsular exopolysacharide rich in sialic acid.BS is characterized by the presence in the cell wall of the antigen group B of Lancefield classification (Lancefield grouping) that can be detected directly in intact bacteria using latex agglutination tests.

Streptococci Alpha-hemolytic streptococci. Most of these species are referred to as a group – viridans streptococci. They are also sometimes referred to as “green strep” owing to the color of blood agar surrounding the colonies. Many different species comprise the viridans streptococci. Notable examples include Streptococcus mitis, S. mitior, and S. sanguis. However clinical microbiology laboratories generally do not have the ability (or the interest) to differentiate one species from the other.

Streptococcus pyogenes (Group A Strep) Group A Strep is the cause of such non-invasive diseases as strep throat and impetigo, as well as much more harmful lethal conditions such as streptococcal toxic shock syndrome (STSS) and necrotizing fasciitis (NF)--also known as flesh-eating disease--among others.n recent years, there has been an increase in the variety and severity of Streptococcus pyogenes infections, including those that are invasive. Though Strep remains susceptible to penicillin, some strains are known to be resistant to macrolides, such as erythromycin, as well as tetracyclines and clindamycin.

About Group B Strep Group B Streptococcus (group B strep) is a type of bacteria that causes illness in people of all ages. Also known as GBS, group B strep disease can be especially severe in newborns, most commonly causing sepsis (infection of the blood), pneumonia (infection in the lungs), and sometimes meningitis (infection of the fluid and lining around the brain and spinal cord).

Streptococcus Streptococcus pneumoniae and a group of oral streptococci (Streptococcus viridans or viridans streptococci) display alpha hemolysis. This is sometimes called green hemolysis because of the color change in the agar.Other synonymous terms are incomplete hemolysis and partial hemolysis.n the medical setting, the most important groups are the alpha-hemolytic streptococci S. pneumoniae and Streptococcus viridans group, and the beta-hemolytic streptococci of Lancefield groups A and B (also known as “group A strep” and “group B strep”).

Coccus Streptococcus (genus Streptococcus), group of spheroidal bacteria belonging to the family Streptococcaceae. The term streptococcus (“twisted berry”) refers to the bacteria’s characteristic grouping in chains that resemble a string of beads. Streptococci are microbiologically characterized as gram-positive and nonmotile.

Scientific Name for Strep Throat Scientific Name for Strep Throat. Strep throat is the most common type of bacterial throat infection; it is caused by group A streptococcus bacteria (GAS for short). The scientific name for strep throat bacteria is Streptococcus pyogenes. This throat infection is most frequently diagnosed during the late fall, winter, and early spring. Symptoms can include fever, white patches of pus on the back of the throat, and a red and painful throat that begins suddenly.
