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.

Group C and G streptococci Unlike the group A streptococcus, the group C and group G streps have not been studied extensively. This is mainly because the diseases due to group C and G are much less common, but also because the diseases caused are less well-recognised.

Streptococcus Streptococcus is a genus of coccus (spherical) Gram-positive bacteria belonging to the phylum Firmicutes and the order Lactobacillales (lactic acid bacteria).

Streptococcus pyogenes (Group A Strep) Streptococcus pyogenes, or Group A Streptococcus, (GAS) is a Gram-positive bacterium and one of the most frequent pathogens found in the normal flora of humans.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.

Infectious Disease Epidemiology Program A: Group A Streptococcus is a bacterium that can cause a wide range of infections. People may also carry group A streptococci in the throat or on the skin and have no symptoms of illness.Most GAS infections are relatively mild illnesses such as strep throat, or impetigo (a skin infection).Occasionally these bacteria can cause severe and even life-threatening diseases.: Group A Streptococcus is a bacterium that can cause a wide range of infections.

- 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.

Bacterial Infections of the Equine Respiratory Tract Lancefield groups. Lancefield grouping is a serological method for classifying streptococci into one of 20 groups (designated by a letter) based on the presence of polysaccharide and teichoic acid antigens in the bacterial cell wall (Lancefield 1933).

Streptococcus pyogenes Streptococcus pyogenes is a species of bacteria. Like most other streptococci, it is clinically important in human illness.It is an infrequent, but usually pathogenic, part of the skin flora. It is the sole species of Lancefield group A and is often called group A streptococcus (GAS), because it displays streptococcal group A antigen on its cell wall.ike most other streptococci, it is clinically important in human illness.

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.

Streptococcal Infections (invasive group A strep, GAS) How are group A streptococci spread? These bacteria are spread by direct contact with nose and throat discharges of an infected individual or with infected skin lesions. The risk of spread is greatest when an individual is ill, such as when people have strep throat or an infected wound.

Background Of the non–group A streptococci, group B is the most important human pathogen (the most common cause of neonatal sepsis and bacteremia), although other groups (particularly group G) have occasionally been implicated as causes of pharyngitis.

Group A Streptococcal (GAS) Infections 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 cases in adults. During the winter and spring in temperate climates, up to 20% of asymptomatic school-aged children may be group A streptococcus carriers. pyogenes also has the potential to produce outbreaks of disease in younger children in daycare. Rheumatic fever is most frequently observed in the age group most susceptible to group A streptococcal infections (ie, children aged 5-15 y).

Is It Strep Throat? Group A Streptococcus (group A strep, GAS) bacteria can live in a person's nose and throat. The bacteria are spread through contact with droplets from an infected person's cough or sneeze.If you touch your mouth, nose, or eyes after touching something that has these droplets on it, you may become ill.ost group A strep infections are relatively mild illnesses such as strep throat, scarlet fever, and impetigo (a skin infection). Occasionally these bacteria can cause severe and even life-threatening diseases.
