[Group A streptococci: serotypes isolated in a pediatric environment]

We examined the incidence of different types of group A Streptococci in children with various (mostly respiratory) diseases. The 85.6% of strains assayed were T typable; they belonged more frequently to "5-11-12-27-44" T complex, to type T12, T1, "3-13-B3264" T complex and T4. An increase of type 1 and 4 was found in streptococcal strains isolated more recently.
