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 strep pharyngitis cause suppurative complications?
Rarely, suppurative and nonsuppurative complications can occur after group A strep pharyngitis. Suppurative complications result from the spread of group A strep from the pharynx to adjacent structures. They can include:
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 bacterial etiology for pharyngitis?
Bacteria are responsible for approximately 5 to 10 percent of pharyngitis cases, with group A beta-hemolytic streptococci being the most common bacterial etiology. A positive rapid antigen detection test may be considered definitive evidence for treatment; a negative test should be followed by a confirmatory throat culture when streptococcal pharyngitis is strongly suspected. Treatment goals include prevention of suppurative and nonsuppurative complications, abatement of clinical signs and symptoms, reduction of bacterial transmission and minimization of antimicrobial adverse effects. Antibiotic selection requires consideration of patients' allergies, bacteriologic and clinical efficacy, frequency of administration, duration of therapy, potential side effects, compliance and cost. Oral penicillin remains the drug of choice in most clinical situations, although the more expensive cephalosporins and, perhaps, amoxicillin-clavulanate potassium provide superior bacteriologic and clinical cure rates. Alternative treatments must be used in patients with penicillin allergy, compliance issues or penicillin treatment failure. Patients who do not respond to initial treatment should be given an antimicrobial that is not inactivated by penicillinase-producing organisms (e.g., amoxicillin-clavulanate potassium, a cephalosporin or a macrolide). Patient education may help to reduce recurrence.
