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.
本文呈现了从儿科患者中分离出的246株呼吸道外链球菌（非A组或D组）的血清学分析结果。采用沃森双酶法获取菌株提取物以进行兰斯菲尔德分组。92.6%的β反应性链球菌可分组；77.8%的γ（无反应性）链球菌可分组；仅20.6%的α反应性链球菌可分组。可分组的链球菌多数属于兰斯菲尔德B组（49.6%），不过也有相当数量的F组（11.4%）和G组（11.8%）。文中讨论了这些菌株在儿科人群中的意义。
