Are the 1st line of treatment for streptococcal pharyngitis?
First-line treatment for GABHS pharyngitis includes a 10-day course of penicillin or amoxicillin. Patients allergic to penicillin can be treated with first-generation cephalosporins, clindamycin, or macrolide antibiotics.
Are the Centor criteria accurate in diagnosing streptococcal pharyngitis?
They are not diagnostic but may be considered to guide further management. The Centor criteria can be used to estimate the probability of streptococcal pharyngitis and are best used in a high prevalence setting (SOR: A, meta-analysis).
Is Group C strep pharyngitis treated?
Non–group A beta-hemolytic streptococci (groups C and G) also can cause acute pharyngitis; these strains are usually treated with antibiotics, although good clinical trials are lacking.
Is Group B Strep pharyngitis treated?
GBS infections are usually treated with penicillin. Sometimes other types of antibiotics are used. Soft tissue and bone infections may require surgery to treat. Treatment often depends on where the bacteria in found in the body.
Is 7 days of amoxicillin enough for strep throat?

How is streptococcal pharyngitis diagnosed?
Clinicians need to use either a rapid antigen detection test (RADT) or throat culture to confirm group A strep pharyngitis. RADTs have high specificity for group A strep but varying sensitivities when compared to throat culture. Throat culture is the gold standard diagnostic test.
What is a positive Centor score?
In adults, the positive predictive value of the Centor criteria for predicting GAS pharyngitis is around 40% if 3 criteria are met, and about 50% if 4 criteria are met. These criteria along with other clinical features should be used to guide treatment for pharyngitis in adults.
How accurate is Centor criteria?
As a decision rule for considering antibiotic prescribing (score ≥ 3), the Centor score has reasonable specificity (0.82, 95% CI 0.72 to 0.88) and a post-test probability of 12% to 40% based on a prior prevalence of 5% to 20%.
Can I take amoxicillin for 3 days only?
Your doctor will advise you how long to take amoxicillin for (usually 3 to 7 days). Always take your amoxicillin exactly as your doctor has told you. The pharmacy label on your medicine will tell you how much to take, how often to take it and any special instructions.
