A total of 171 taxa was represented among 1,900 bacterial isolates from 60 samples of sites affected with moderate periodontitis in 22 mature adult humans. The composition of the subgingival sulcus flora was statistically significantly different from that of the adjacent supragingival flora and the subgingival flora of 14 people with healthy gingiva, but was not significantly different from that of sulci affected with severe periodontitis in 21 young human adults. The sulcus floras of moderate periodontitis and severe periodontitis shared many of their predominant bacterial species, but there were differences in the relative proportions of some of these species. Similar relationships were found for seven taxa of treponemes that were cultured from the samples.
在来自22名成年患者60份中度牙周炎患部样本的1900株细菌分离物中,共鉴定出171个分类单元。患部龈下菌斑菌群的组成与相邻的龈上菌斑菌群以及14名牙龈健康者的龈下菌斑菌群在统计学上有显著差异,但与21名年轻成年人重度牙周炎患部龈沟的菌群无显著差异。中度牙周炎和重度牙周炎患部龈沟菌群有许多共同的优势菌种,但其中一些菌种的相对比例存在差异。从样本中培养出的7个密螺旋体分类单元也发现了类似的关系。
