Inclusion criteria

Inclusion criteria: The study subjects were suspected of having acute pharyngeal tonsillitis due to Streptococcus pyogenes infection. Clinical diagnoses were made on the basis of reference symptoms, such as fever, sore throat, malaise, and headache with acute onset, whereas the physical findings that suggested the infection included prominent pharyngeal redness, tonsil swelling with exudate, and cervical lymphadenopathy. The study subjects underwent rapid antigen test using a throat swab and isolation culture tests, in which Streptococcus pyogenes was detected.

Exclusion criteria

Exclusion criteria: Patients with a history of penicillin allergies or those who received antibacterial drugs within the previous 4 weeks were excluded from this study.
