使用专门设计的厌氧采样装置和当前的厌氧方法，对 5 名患者的牙周病病变的主要可培养微生物群进行了研究。从每位患者身上采集牙周病变根尖部分的两份样本和临床正常部位的一份样本。结果表明，与对照位点中主要的革兰氏阳性菌群相比，从口袋位点获得的样品由显着增加比例的革兰氏阴性厌氧杆组成。其中许多生物体无法分类。另外对 9 名牙周病患者进行了取样，并确定分离出与前 5 名患者相似的革兰氏阴性厌氧棒组。根据形态、培养和生化特征，这些生物体被分为 5 类。
The predominant cultivable microbiota of periodontosis lesions was studied in 5 patients using a specially designed anaerobic sampling device and current anaerobic methodology. Two samples from the apical portion of periodontosis lesions and one sample from clinically normal sites were taken from each patient. The results indicated that samples obtained from pocket sites consisted of significantly increased proportions of Gram negative anaerobic rods when compared to a predominantly Gram positive flora in the control sites. Many of these organisms could not be classified. An additional 9 periodontosis patients were sampled and it was determined that groups of Gram negative anaerobic rods from similar to the first 5 patients were isolated. These organisms were differentiated into 5 groups based on morphologic, cultural, and biochemical characteristics.
