Description:

Haemolytic streptococcus BACTERIAL PHARYNGOTONSILLITIS Etiology Group A beta-haemolytic streptococcus is the most common and impoant pathogen causing acute bacterial pharyngotonsillitis. This infection most commonly presents in children aged 5-6 yrs. SYMPTOMS It is characterized by fever, dry sore throat, cervical adenopathy, dysphagia and odynophagia. The tonsils and pharyngeal mucosa are erythematous and may be covered with purulent exudate; the tongue may also become red (strawberry tongue). DIAGNOSIS In cases of strongly suspected pharyngitis caused by group A beta hemolytic streptococcus the combination of rapid strep tests based on ELISA (enzyme-linked immunosorbent assay) or latex agglutination, with a throat culture if negative, increases the sensitivity and specificity of either test alone. TREATMENT The primary antibiotic treatment for streptococcal pharyngotonsillitis consists of penicillin.
