Abstract

The prevalence of the smooth and rough colonial morphotypes of Peptostreptococcus micros was examined with culture technique in 123 patients with adult periodontitis (age 24-68 years). Of all subgingival samples, 91% contained the smooth morphotype of P. micros. The smooth morphotype constituted a mean percentage of the total anaerobic viable biota of 6.0%, with a range of 0.02-35.7%. Of these samples, 49% contained colonies of the rough morphotype as well, with a mean percentage of the total anaerobic viable biota of 2.3% (range 0.01-16.2%). None of the samples contained only the rough morphotype. The total percentage of P. micros varied from 0.02-35.71% with a mean of 7.2%. No correlation was found between the prevalence of both morphotypes of P. micros and the age of the subjects or with loss of attachment or pocket depth.

摘要

采用培养技术对123例成人牙周炎患者（年龄24 - 68岁）检测微小消化链球菌光滑型和粗糙型菌落形态的流行情况。在所有龈下样本中，91%含有微小消化链球菌的光滑型。光滑型在总厌氧活菌生物群中所占平均百分比为6.0%，范围为0.02 - 35.7%。在这些样本中，49%也含有粗糙型菌落，其在总厌氧活菌生物群中所占平均百分比为2.3%（范围0.01 - 16.2%）。没有样本仅含有粗糙型。微小消化链球菌的总百分比在0.02 - 35.71%之间，平均为7.2%。未发现微小消化链球菌两种菌落形态的流行情况与受试者年龄、附着丧失或牙周袋深度之间存在相关性。
