本研究应用厌氧培养方法,对50例感染根管(有临床症状者37例,无临床症状者13例)进行了细菌的定量培养,对产黑色素拟杆菌群进行了分离鉴定并观察了其与临床症状的关系。结果,从33例中共分离出61株(计7种)产黑色素拟杆菌群细菌,总检出率为66％,有症状组检出率为78.4％,无症状组为30.8％。不解糖菌株均存在于有症状组。说明产黑色素拟杆菌群细菌与临床症状有关,尤以不解糖菌株关系更密切。
In this study, anaerobic culture method was used to quantitatively culture 50 cases of infected root canals (37 cases with clinical symptoms and 13 cases without clinical symptoms), and to isolate and identify the group of melanobacteria. Relationship with clinical symptoms. As a result, 61 strains (7 species) of Bacteroides melanogaster were isolated from 33 cases. The total detection rate was 66%. The detection rate of symptomatic patients was 78.4% and that of asymptomatic patients was 30.8%. Unfavorable sugar strains are present in the symptomatic group. Note that the production of melanobacteria group of bacteria and clinical symptoms, especially in non-sugar-linked strains more closely.
