title: ["In vitro" susceptibility of group A beta-haemolytic streptococcus].
abstract: An epidemiological survey on 827 pediatric patients has been performed from March '95 to November '96 to verify the incidence of streptococcal etiology during acute pharyngo tonsillitis in pediatric age and the "in vitro" susceptibility of the group A beta hemolytic Streptococcus isolates. S. pyogenes was responsible of acute pharyngo tonsillitis in 32.7% of cases. No strain was resistant to beta lactams, but resistance to erythromycin was high (38.7% of bacterial isolates). These results suggest the importance of a constant epidemiological surveillance of bacterial resistance of S. pyogenes in the community setting.
