Streptococcus dysgalactiae consists of at least five distinct subgroups on the basis of serogroups, biotypes, and hosts. A chemotaxonomic and phenotypic examination of 80 S. dysgalactiae strains representing the known diversity within this species and 49 reference strains representing all members of the streptococcal pyogenic species group revealed two subpopulations of strains within S. dysgalactiae. The name S. dysgalactiae subsp. dysgalactiae is proposed for strains of animal origin. These strains belong to Lancefield serogroups C and L, are alpha-, beta-, or nonhemolytic, and do not exhibit streptokinase activity on human plasminogen or proteolytic activity on human fibrin. The name S. dysgalactiae subsp. equisimilis is proposed for human isolates. These strains belong to Lancefield serogroups C and G, are beta-hemolytic, and exhibit streptokinase activity on human plasminogen and proteolytic activity on human fibrin.
根据血清群、生物型和宿主，乳房链球菌至少由五个不同的亚群组成。对代表该物种内已知多样性的80株乳房链球菌菌株和代表化脓性链球菌物种组所有成员的49株参考菌株进行化学分类和表型检查，发现乳房链球菌内有两个菌株亚群。建议将动物源菌株命名为乳房链球菌亚种乳房亚种。这些菌株属于兰斯菲尔德血清群C和L，为α-、β-或非溶血性，对人纤溶酶原不表现链激酶活性，对人纤维蛋白也不表现蛋白水解活性。建议将人类分离株命名为乳房链球菌亚种似马亚种。这些菌株属于兰斯菲尔德血清群C和G，为β-溶血性，对人纤溶酶原表现链激酶活性，对人纤维蛋白表现蛋白水解活性。
