Abstract
A group G streptococcal strain was coated with antibody against six different serotypes (Ia, Ib, II, III, IV, and V) of group B streptococci. The coagglutination patterns of 114 strains of group B streptococci were compared with the serotypes determined after immunoprecipitation. The specificity of the method was 100% and the sensitivity 97%. It was used for the typing of 89 invasive and 101 colonizing isolates. The new method is swift, specific, and highly sensitive. It consumes only minute amounts of antibody.
摘要
一株A群链球菌菌株用抗B群链球菌六种不同血清型（Ia、Ib、II、III、IV和V）的抗体包被。将114株B群链球菌的协同凝集模式与免疫沉淀后确定的血清型进行比较。该方法的特异性为100%，敏感性为97%。它被用于89株侵袭性分离株和101株定植分离株的分型。这种新方法快速、特异且高度敏感。它仅消耗微量抗体。
