The recovery of beta-hemolytic streptococci from throat swab specimens, from 1973 through 1975, was analyzed. Group A and nongroup A beta-hemolytic streptococci were recovered from 16.5% and 16.1%, respectively, of the specimens received. Although the recovery of group A streptococci fluctuated during the year, with the greatest incidence during the winter and spring months, the recovery of nongroup A streptococci was constant throughout the year. The proportion of group A to nongroup A streptococci was significantly greater in specimens collected during the winter and spring months than in those collected during the summer and fall months, and in specimens from pediatric patients than in those from adults.
对1973年至1975年期间从咽拭子标本中分离出的β溶血性链球菌进行了分析。在收到的标本中，A组和非A组β溶血性链球菌的分离率分别为16.5%和16.1%。虽然A组链球菌的分离率在一年中有所波动，在冬季和春季月份发病率最高，但非A组链球菌的分离率全年保持稳定。冬季和春季月份采集的标本中A组与非A组链球菌的比例显著高于夏季和秋季月份采集的标本，儿科患者标本中的比例高于成人标本。
