One hundred and ten clinical specimens from mouth, thoracic cavity, pelvis and abdominal cavity were collected. These specimens were transoorted in sutable medium & brought immediatly to our laboratory and anaerobic microorganisms were isolated and cultured with the aid of anaerobic glove box (Forma Anaerobic System, Model 1029) or Gas-Pak method. Among 110 specimens, anaerobic bacteria were isolated from 64 specimens, the frequency of isolation was 58%. Positive rate reached 100%,;in periodontitis, 85% in pulpitis, 83% in appendicil abscess and peritonitis, 39% in specimens from biliary tract, 57% in empyema of the chest, 33% in pelvic peritonitis. Anaerobic bacteria were not found in early stage of acute appendicitis and cystic goiter complicated with infection of five cases respectively. 370 strains of anaerobic bacteria were isoslated from 64 positive cases in clinical specimens. They belong to 11 genera and 32 species (74 strains unidentified). Among them, the most frequently seen were Bacteroides 45.9% (B.fragilis were 37.6% in Bacteroides), next, Fusobacterium and Peptostreptococeus, both of them, 15.1%. Gram-positive non-sporing bacteria 80%, Clostridium 8.9%, besides, Capnocytophaga (2.9%),veillonella(1.3%), streptococcus and Leptotriehia (both 2.9%)etc. In the direct method of micro-biochmical determination for enzyme and GLC in analysing the metabolic products. These methods were found sensitive & more valuable in indentification of anaerobic bacteria than conventional Lab. methods.

我们从口腔、胸部、腹部和盆腔等处采集了110份临床感染标本,以自制的输送培养基立即送实验室,在厌氧手套箱(霍尔玛厌氧系统1029型)或Gas-pak罐中,行厌氧菌的分离和培养,其中64份标本检出厌氧菌,阳性率为58%。临床标本中牙周炎标本厌氧菌检出率高达100%,牙髓炎标本为85%,阑尾脓肿和腹膜炎标本为83%,胆道标本为39%,脓胸标本为57%,盆腔标本为33%,早期单纯性阑尾炎和甲状腺囊肿合并感染的标本各5份,都未检出厌氧菌。从64份阳性分离的标本中共分离到厌氧菌370株,经鉴定分别属于11个菌属32个菌种(未定种的有74株),其中类杆菌最多占45.9%(类杆菌属中脆弱类杆菌占37.6%),次为梭杆菌属和消化链球菌属,各占15.1%。革兰氏阳性无芽胞厌氧菌占8%左右,而梭菌属为8.9%,其余是二氧化碳噬纤维菌属(2.9%)、韦荣氏球菌属(1.3%)、链球菌属和纤毛菌属(1.5%)等。在厌氧菌鉴定中,我们使用了微量生化直接酶测定技术和代谢产物的气相色谱分析技术,这些方法在厌氧菌鉴定中比常规方法敏感且有较大的价值。

20 subginggival plaque samples from 17 adult periodontitis (AP) patients and 9 gingival plaque samples from 9 healthy adults were cultured and identified. After analysing 18 main bacterial genera (species), we got the result that the composition of periodontal microflora and the predominant bacteria in the AP patients and the healthy individuals were quite different. In AP group, the flora were chiefly formed of Gram negative anaerobic bacilli (60.8%) and the predominant bacterial species were identified as B. gingivalis of the Black-pigmented Bacteroides. However the normal flora of control group were mainly made up with Gram positive facultative cocci(69.2%), among which the predominant bacterial species were Streptococcus spp. and so on. In addition, F. nucleatum. V. parvula, E. corrodens and some spirochetes were also found to be present in a higher figure in AP group than in the control. From the microecologic point of view, we think that AP might be a result of unbalance bet- ween hosts and their microflora. Several species of bacteria have been associated with this disease. B. gingivalis which has a notable quantitave change might play an important role in the develpment of the disease.

本文用2种非选择性培养基和12种选择性培养基对17名北京市成年牙周炎病人和9名健康对照者龈下及龈沟菌斑菌群进行了培养、分离和鉴定。结果,牙周炎患者龈下菌斑的菌群主要由专性厌氧的革兰氏阴性杆菌组成(60.8%),优势菌为牙龈拟杆菌等;而对照组的菌群主要由兼性厌氧的革兰氏阳性球菌组成(69.2%),优势菌为链球菌属等。这种菌群构成,两组样本存在显著性差异,对于我们认识牙周炎的病原及有关微生态学问题可能有重要意义。
