Tonsillitis due to Streptococcus pyogenes

Tonsillitis due to *Streptococcus pyogenes* is an acute bacterial infection of the palatine tonsils and surrounding oropharyngeal tissue caused by group A beta-hemolytic streptococci Left untreated, the infection carries a risk of suppurative complications, including peritonsillar abscess, as well as delayed immune-mediated sequelae such as acute rheumatic fever and poststreptococcal glomerulonephritis

Most prevalent in school-aged children and adolescents, the pathogen adheres to and invades the mucosal epithelium using virulence determinants such as M protein, triggering intense local inflammation Defining clinical features include an abrupt onset of sore throat, odynophagia, fever, tonsillar erythema and edema often accompanied by patchy exudates, and tender anterior cervical lymphadenopathy, characteristically without typical viral symptoms such as cough or rhinorrhea
