摘要

从喉部培养中新鲜分离的A组链球菌(3株t - 1型、2株t - 2型和3株t - 4型)在血琼脂上连续传代25次。在传代过程中,所有菌株的M蛋白产量和/或不透明因子(OF)活性都发生了变化。研究了每个菌株在传代前后对来自6个健康个体的口腔细胞池的粘附能力。6株of活性/M蛋白产量降低的菌株中有5株的粘附能力显著下降,而2株of活性增加的菌株中有1株的粘附能力较好。本文就无症状A群链球菌携带者的临床观点进行了讨论。

Repeated passage of freshly isolated group A streptococci on blood agar. II. Effect on adherence capacity.

Group A streptococcal strains (three T-type 1, two T-type 2 and three T-type 4), freshly isolated from throat cultures, were subjected to 25 serial passages on blood agar. All strains changed their M protein production and/or opacity factor (OF)-activity during the passages. The capacity of each strain to adhere to a pool of buccal cells from six healthy individuals was studied both before and after passage. Five of six strains with decreased OF-activity/M protein production diminished significantly in adherence capacity, whereas one of two strains with increasing OF-activity adhered better to the epithelial cells. The results are discussed in relation to the clinical view of asymptomatic carriers of group A streptococci.
