causes a muffled voice. Uvula is deviated to the unaffected side and swelling and
redness around the affected tonsil is remarkable. Bacterial examination from the peritonsillar
pus often reveal streptococcus group A beta-hemolytic as the aerobic bacteria and
the detection rate of anaerobic bacteria also amounted to more than half. The treatment
