Extrarespiratory non-group A, non-group D isolates of streptococci.
The results of serologic analysis of 246 extrarespiratory isolates of streptococci (non-group A or D) obtained from pediatric patients are presented. Watson's double enzyme method was used to obtain the extracts of the organisms for Lancefield grouping. Ninety-two and six tenths percent of beta reacting streptococci were groupable; 77.8 per cent of gamma (nonreacting) were groupable; only 20.6 per cent of the alpha reacting streptococci were groupable. The majority of the groupable streptococci belonged to Lancefield group B (49.6 per cent), although significant numbers of group F (11.4 per cent) and group G (11.8 percent) were present. The significance of the organisms in a pediatric population is discussed.
