As a further antigen in Streptococcus pyogenes has the M-protein. This feature allows the subdivision into serovars.

Is Streptococcus pyogenes gram positive?
Streptococcus pyogenes is one of the gram-positive cocci in chains overlap. The cell walls of streptococcal cells has some interesting features. The high content of peptidoglycan (murein layer) of carbohydrate (C polysaccharide) gives the cells a very strong structure. The C-polysaccharide antigen is effective.
What is the reservoir of streptococcus pyogenes?
Reservoir of Streptococcus pyogenes is the human. In particular, the throat is colonized, preferably in the winter months. As virulence is the M protein, which enables the propagation of the streptococci in the host only. The cell wall peptidoglycan and especially the complex of C polysaccharide exerts a tissue toxicity, which also emanates from dead cells of streptococci. They also provide a number of group A streptococcal exotoxins. The haemolysins streptolysin O and S destroy the membranes of red blood cells and other cells. Streptolysin O acts as an antigen that can be detected by measuring antibodies against this toxin (antistreptolysin titer). The pyrogenic streptococcal exotoxin (PSE) A, B, C are responsible for fever, rash, and scarlet, and enanthema in sepsis and toxic shock syndrome. They act as superantigens, causing a release of large amounts of cytokines. The enzymes streptokinase, DNAse and hyaluronidase favor the spread of infection in the tissue.
What is scarlet fever?
Scarlet fever is a special form of streptococcal pharyngitis, observed with the addition of a speckled rash of angina (and enanthema) is. A second group of diseases are infections of the skin (pyoderma, impetigo, erysipelas) dar. a very serious disease is necrotizing fasciitis, with or without the myositis.

Is penicillin a macrolide?
In penicillin allergy a macrolide antibiotic is considered. However, 8-15% of isolates are resistant to macrolides. The spectrum of activity of telithromycin (Ketek) also captures the majority of macrolide-resistant strains. Fluoroquinolones and cotrimoxazole (EUSAPRIM, COTRIM HEXAL FORTE, etc.) do not work reliably.

Are based on a currently available rapid antigen detection tests according to the Robert Koch Institute is not sensitive enough. Antibody detection assays are useful only in cases of suspected streptococcal sequelae.
What is the treatment for impetigo?

What is strep pharyngitis?
Group A strep pharyngitis is an infection of the oropharynx caused by S. pyogenes. S. pyogenes are gram-positive cocci that grow in chains ( see figure 1 ). They exhibit β -hemolysis (complete hemolysis) when grown on blood agar plates. They belong to group A in the Lancefield classification system for β-hemolytic Streptococcus, and thus are called group A streptococci.
How is strep pharyngitis transmitted?
Typically transmission occurs through saliva or nasal secretions from an infected person. People with group A strep pharyngitis are much more likely to transmit the bacteria to others than asymptomatic pharyngeal carriers.
Can a RADT be positive?
Clinicians can use a positive RADT as confirmation of group A strep pharyngitis in children. However, clinicians should follow up a negative RADT in a child with symptoms of pharyngitis with a throat culture. Clinicians should have a mechanism to contact the family and initiate antibiotics if the back-up throat culture is positive.
What is the most common cause of pharyngitis in children?
Viruses are the most common cause of pharyngitis in all age groups. Experts estimate that group A strep, the most common bacterial cause, causes 20% to 30% of pharyngitis episodes in children. In comparison, experts estimate it causes approximately 5% to 15% of pharyngitis infections in adults.
How common is group A strep?
Humans are the only reservoir for group A strep. It is most common among children 5 through 15 years of age. It is rare in children younger than 3 years of age. In the United States, group A strep pharyngitis is most common during the winter and spring.
Can you take penicillin for pharyngitis?
Clinicians should not treat viral pharyngitis with antibiotics. Penicillin or amoxicillin is the antibiotic of choice to treat group A strep pharyngitis. There has never been a report of a clinical isolate of group A strep that is resistant to penicillin.
Do carriers of strep have RADT?
Asymptomatic group A strep carriers usually do not require treatment. Carriers have positive throat cultures or are RADT positive, but do not have clinical symptoms or an immunologic response to group A strep antigens on laboratory testing. Compared to people with symptomatic pharyngitis, carriers are much less likely to transmit group A strep to others. Carriers are also very unlikely to develop suppurative or nonsuppurative complications.
