摘要

We isolated Streptococcus dysgalactiae subsp. equisimilis with Lancefield's group A antigen from a patient in Osaka City. This clinical isolate formed beta-hemolytic large colonies on sheep blood agar, and was catalase-negative gram-positive cocci carrying Lancefield's group A antigen. Therefore, Streptococcus pyogenes and this clinical isolate could not be classified by the conventional method on the basis of Lancefield's group antigen. In addition, the rapid detection system of group A streptococci based on group A antigen detection techniques could not divide into two species. Recently, S. dysgalactiae subsp. equisimilis with Lancefield's group G antigen has been isolated from severe invasive streptococcal infection in an increasing frequency in Japan. A possibility that group A S. dysgalactiae subsp. equisimilis cause a serious infection from now on cannot be denied. Thus the discrimination of S. pyogenes from group A S. dysgalactiae subsp. equisimilis is very important. To identify beta-hemolytic streptococci, it is necessary to consider a serogrouping test as one of characteristics of streptococci, and to identify by checking biochemical tests like the PYR test.

Dysgalactiae Subsp。与Lancefield的G抗原组的平衡已经从日本的频率上增加，从严重的侵袭性链球菌感染中分离出来。患者群体的可能性。 Equisimilis引起现在严重的感染不能被拒绝。因此，来自A组的S. pyogaenes的鉴别。 Equisimilis非常重要。为了鉴定β-溶血性链球菌，有必要将血清选项试验作为链球菌的特征之一，并通过检查像Pyr试验等生物化学测试。
