Treatment of Streptococci Infection
B-haemolytic streptococci are among the most susceptible pathogens to antimicrobial agents. Penicillin is the drug of choice in the treatment of S. pyogenes infection. Where a history of hypersensitivity to penicillin exits, erythrocmycin may be used instead. Prophylactic penicillin is often given to patients with rheumatic fever in order to prevent a recurrence.
