采用滚管培养技术对慢性牙龈炎患者龈沟内的优势可培养微生物进行了研究。样本取自9名25- 42岁的个体。革兰氏阳性杆菌占29.1%，主要包括内氏放线菌、以色列放线菌和粘性放线菌。缓症链球菌和血链球菌共占26.8%。消化链球菌平均占回收微生物的3.0%。革兰氏阴性厌氧杆菌占总分离株的25.0%，其中具核梭杆菌、产黑色素拟杆菌SS.中间体赭色拟杆菌、其他拟杆菌、生痰月单胞菌和弯曲杆菌是最主要的分离株。副流感嗜血杆菌和韦荣球菌分别占可培养菌群的14%和4.3%。这些数据表明，慢性牙龈炎的龈下菌群不同于健康的牙周组织和先进的成人和青少年牙周炎。这可能表明不同的感染过程可能在各种牙周病临床实体中起作用。
A study on the predominant cultivable microorganisms inhabiting gingival crevices affected with a chronic gingivitis was carried out using the roll tube culture technique. Samples were obtained from nine individuals 25--42 years of age. Gram-positive rods make up 29.1% of the isolates and included mainly Actinomyces naeslundii, Actinomyces israelii, and Actinomyces viscosus. Streptococcus mitis and Streptococcus sanguis together made up 26.8% of the cultivable organisms. Peptostreptococcus averaged 3.0% of the organisms recovered. Gram-negative anaerobic rods constituted 25.0% of the total isolates with Fusobacterium nucleatum, Bacteroides melaninogenicus ss. intermedius. Bacteriodes ochraceus, other Bacteroides species, Selenomonas sputigena, and Campylobacter sputorum as the most predominant isolates. Haemophilus parainfluenzae averaged about 14% and Veillonella species 4.3% of the cultivable microflora. The data presented indicate that the subgingival microflora of a chronic gingivitis differs from those of healthy periodontium and advanced adult and juvenile periodontis. This might suggest that different infectious processes may be operative in various clinical entities of periodontal disease.
