摘要
通过G + C mol%、DNA-DNA水化、表型和血清学检测,确定了口腔中间链球菌与相关链球菌的分类学关系。结果表明,1组中间葡萄球菌包括ATCC 27335型菌株和5株中间葡萄球菌与2组中间葡萄球菌包括ATCC 31412型菌株和2株中间葡萄球菌在遗传、表型和血清学特征上表现出明显的差异。因此,9株口腔中间链球菌至少可分为两个同源群。
Genetic and physiological characteristics of oral Streptococcus intermedius.
The taxonomic relationships among strains of oral Streptococcus intermedius and the related streptococci were determined by G + C mol%, DNA-DNA hydridization, phenotypical and serological tests. As to the results, group 1 strains of S. intermedius including the type strain ATCC 27335 and five isolates behaved distinctively with respect to genetic, phenotypic and serological characteristics compared with group 2 strains of S. intermedius including ATCC 31412 and two isolates. Therefore, nine strains of oral S. intermedius could be separated at least into two homology groups.
