Abstract
A mutant of Streptococcus mutans 6715 wild type designated C307 has been shown to possess a small amount of either Lancefield- or Rantz-Randall-extractable serotype antigen. Quantitative analysis employing combined immunoabsorption and radial immunodiffusion of anti-S. mutans serotype-specific serum demonstrated that C307 exhibited less than 1% of the amount of serotype g antigen normally expressed in S. mutans 6715 wild type.
摘要
变形链球菌6715野生型的一个突变体，命名为C307，已被证明含有少量可被兰斯菲尔德或兰茨-兰德尔提取的血清型抗原。采用抗变形链球菌血清型特异性血清的联合免疫吸附和放射免疫扩散进行定量分析表明，C307所表现出的血清型g抗原量不到变形链球菌6715野生型中正常表达量的1%。
