着色普雷沃氏菌属与口腔感染有关，也是健康牙龈植物群的一部分。本研究的目的是确定是否存在色素普雷沃氏菌属。牙周健康成年人的唾液和龈沟样本中。本研究选择了12名无囊袋>或= 4 mm，探查后无出血的白人女性受试者（平均年龄28岁，范围21-36岁）。首先收集石蜡刺激的唾液，然后用无菌刮匙从所有第一磨牙的近颊面采集龈下细菌样本。将样品接种到非选择性和选择性培养基上，并进行厌氧孵育。分离出的最常见菌种为产黑色素伪杆菌、中间伪杆菌和罗氏伪杆菌，分别见于11例、10例和9例受试者。唾液/龈下样本中总可培养厌氧微生物的平均百分比为：产黑色素普氏菌14.7/0.6，中间普氏菌3.1/5.3，罗氏普氏菌2.6/1.2。在一个唾液样本中发现了齿垢伪菌，在两个龈下样本中发现了体伪菌。不同色素普雷沃氏菌属的数量。同口2-4例，平均2.75例。结论：产黑素菌、中间菌和罗氏菌是牙周健康口腔中常见的微生物。
Pigmented Prevotella spp. have been connected with oral infections as well as being part of the healthy gingival flora. The aim of this study was to determine the presence of pigmented Prevotella spp. in saliva and gingival crevice samples from periodontally healthy adults. Twelve Caucasian female subjects (mean age 28 years, range 21-36 years) with no pockets > or = 4 mm, nor bleeding after probing were selected for this study. Paraffin-stimulated saliva was collected first; then, a pooled subgingival bacterial sample was taken with a sterile curette from mesiobuccal surfaces of all first molars. The samples were inoculated on to non-selective and selective media and incubated anaerobically. The most frequent species isolated were Pr. melaninogenica, Pr. intermedia and Pr. loescheü, found in 11, ten and nine subjects, respectively. The mean percentage of the total cultivable anaerobic microflora in salivary/subgingival samples were 14.7/0.6 for Pr. melaninogenica, 3.1/5.3 for Pr. intermedia and 2.6/1.2 for Pr. loescheii. Pr. denticola was found in one saliva sample and Pr. corporis, in two subgingival samples only. The number of different pigmented Prevotella spp. in the same mouth was 2-4 (mean 2.75). In conclusion, Pr. melaninogenica, Pr. intermedia and Pr. loescheii seem to be common microorganisms in the periodontally healthy oral cavity.
