Molecular analysis of Streptococcus pyogenes strains isolated from patients with recurrent pharyngitis after oral amoxicillin treatment.

CONCLUSION: When recurrent pharyngitis emerges more than 40 days after the last treatment, penicillin can be prescribed again because reinfection is suspected. However, when recurrent pharyngitis takes place within 40 days after completing the treatment, alternative drugs should be considered for retreatment because the pharyngitis is likely to be due to reactivation.
