对16名患者的110个牙周部位（牙周袋深度为6 mm或更深）的一式两份样本进行分析，以确定是否存在伴放线杆菌、牙龈卟啉单胞菌、中间普雷沃氏菌、二氧化碳噬纤维菌属、弯曲杆菌，腐蚀艾肯氏菌和具核梭杆菌。在非手术牙周治疗前后对这些部位进行取样。处理前，在任何分析的种属之间均未发现统计学显著相关性。治疗后，E。corrodens和所有其它种类，F. nucleatum和P. intermedia;二氧化碳嗜纤维菌属（Capnocytophaga spp.）和C.腹直肌;中间变形杆菌vs二氧化碳嗜纤维菌属。和牙龈卟啉单胞菌;和C.腹直肌vs二氧化碳嗜纤维菌属和A.伴放线菌其中一些关联可以通过患者相关因素或部位相关特征（如囊袋深度）来解释。牙龈卟啉单胞菌的比例似乎与样本中中间卟啉单胞菌的比例无关。如果在患者的一个采样袋中发现一种分析的微生物，则在治疗前在同一患者的所有采样部位发现该微生物的概率超过50%。对于许多种属，特别是牙龈卟啉单胞菌，治疗后这种概率降低，其概率为零。对于研究的所有菌种，如果在同一个体中的一个部位上存在细菌菌种，则在至少一个额外部位上检测到细菌菌种的概率接近100%（治疗前后）。这项研究显示了几个潜在的微生物协会在龈下菌斑植物群的深牙周袋。（250字处删节）
Duplicate samples from 110 periodontal sites of 6 mm or more pocket depth in 16 patients were analyzed for the presence of Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Prevotella intermedia, Capnocytophaga spp., Campylobacter rectus, Eikenella corrodens and Fusobacterium nucleatum. The sites were sampled before and after nonsurgical periodontal treatment. No statistically significant associations were found before treatment between any of the analyzed species. After treatment, statistically significant associations were found between E. corrodens and all the other species, F. nucleatum and P. intermedia; Capnocytophaga spp. and C. rectus; P. intermedia vs Capnocytophaga spp. and P. gingivalis; and C. rectus vs Capnocytophaga spp. and A. actinomycetemcomitans. Some of these associations could be explained either by patient-related factors or site-related characteristics such as the pocket depth. The proportion of P. gingivalis seemed to be unrelated to the proportion of P. intermedia in the samples. If one of the analyzed microbes was found in one of the sampled pockets in a patient, the probability of finding that microbe in all the sampled sites in the same patient before treatment was more than 50%. This probability was reduced after treatment for many species, especially P. gingivalis, which showed a probability of zero. The probability of detecting a bacterial species on at least one additional site if it was present on one in the same individual was nearly 100%, both before and after treatment, for all species studied. This study has shown several potential microbial associations in the subgingival plaque flora of deep periodontal pockets.(ABSTRACT TRUNCATED AT 250 WORDS)
