Final answer:
The first-line recommended treatment for bacterial pharyngitis caused by Group A beta-hemolytic streptococci is antibiotics, specifically penicillin-related drugs like amoxicillin or penicillin G. Pain relievers and bed rest are used to ease symptoms and support recovery but are not primary treatments for the infection itself.
Step-by-step explanation:
The first-line recommended treatment against Group A beta-hemolytic streptococci (GABHS), the most common cause of bacterial pharyngitis, is antibiotics. Penicillin is commonly prescribed for treatment, as resistance among streptococci is not widespread currently. While pain relievers such as nonsteroidal anti-inflammatory drugs (NSAIDs) may be used to alleviate symptoms, and bed rest might be advised to promote recovery, they are not primary treatments for the actual infection.
It is critical to obtain proper diagnosis and treatment for strep throat because if left untreated, it can lead to serious complications. A throat culture is the gold standard for diagnosis. Upon confirmation of strep throat caused by Streptococcus pyogenes, a necessary course of antibiotics, like oral amoxicillin or intramuscular penicillin G, should be completed fully to prevent antibiotic resistance.
