作者对20名牙周病患者的牙周袋作微生物分析,发现所有病例中均有轻症链球菌Streptococcus mitis和涎链球菌Streptococcus salivaries,30％病例有卡他奈瑟氏菌。于是用以上三种纯种细菌培养后,离心沉淀制成细菌混悬液。以上混悬液用2个方法分别处理:(1)与异性硫氰酸萤光素(FITC)结合,(2)将菌液多次注入兔,以形成抗血清。 The authors analyzed the periodontal pocket of 20 patients with periodontal disease for microbial analysis and found that Streptococcus mitis and Streptococcus salivaries were present in all cases and Neisseria catarrhalis in 30% of cases. So with the above three purebred bacteria culture, centrifuged to make a bacterial suspension. The above suspension was separately treated by two methods: (1) binding to FITC, and (2) multiple instillation of the bacterial liquid into the rabbit to form an antiserum.
