Subgingival plaque bacteria

Isolation and Identification of bacteria from subgingival plaque with low susceptibility to minocycline Regulation of the aceI multidrug efflux pump gene in Acinetobacter baumannii Susceptibility in vitro of canine methicillin-resistant and -susceptible staphylococcal isolates to fusidic acid, chlorhexidine and miconazole: opportunities for topical therapy of canine superficial pyoderma Although up to 99.9% of bacteria in the plaque samples were killed by a 6 h exposure to 8.0 μg/ml of minocycline, large numbers of viable bacteria remained. These results imply that adequate reductions in the numbers of viable subgingival plaque bacteria are unlikely to occur after exposure to minocycline at concentrations attainable in gin‐gival crevicular fluid after systemic administration. Key words: microbiology ; bacteria subgingival plaque; ecology: periodontal Accepted for publication 14 May 1997 The complexity of the subgingival microbiota has been recognized since the 1st microscopic examination of this ecosystem by Van Leeuwenhoek in 1683 (Tal, 1980). Since that time, numerous studies have evaluated the composition Abstract The purpose of this study was to determine the susceptibility to chlorhexidine of a range of bacteria which may be isolated from subgingival plaque. In addition, the effect of chlorhexidine on the survival of bacteria in subgingival plaque samples from patients with chronic inflammatory periodontal disease was investigated. Bacteria of dental plaque under the microscope.

Similarly to the red complex, all species in the orange complex showed a significant association with increasing pocket depth. Subgingival biofilm is plaque that is located under the gums. It occurs after the formation of the supragingival biofilm by a downward growth of the bacteria from above the gums to below. This plaque is mostly made up of anaerobic bacteria, meaning that these bacteria will only survive if there is no oxygen.

They were the earliest bacteria to be isolated and named from the human subgingival plaque. Common Capnocytophaga species are: Capnocytophaga ochracer, Capnocytophaga sputigena, Capnocytophaga gingivalis, Capnocytophaga granulose, and Capnocytophaga heamolytica. Subgingival biofilm is plaque that is located under the gums. It occurs after the formation of the supragingival biofilm by a downward growth of the bacteria from above the gums to below. This plaque is mostly made up of anaerobic bacteria, meaning that these bacteria will only survive if there is no oxygen. Four samples (subgingival and supragingival plaques, saliva, and tongue coating) per each subject were collected from 14 patients with a broad range of severity of periodontitis before periodontal therapy. The bacterial composition was analyzed by 16S rRNA gene amplicon sequencing using Ion PGM. In a recent molecular study, the most predominant bacterial species found in the subgingival plaque were Streptococcus spp., Fusobacterium, Leptotrichia buccalis, Corynebacterium matruchotii, S. oralis and S. mitis .

(1994) found that P. intermedia was always detected in the presence of F. nucleatum in subgingival plaque samples from deep pockets in a group of adult periodontitis subjects. Similarly to the red complex, all species in the orange complex showed a significant association with increasing pocket depth. Subgingival biofilm is plaque that is located under the gums.

This study evaluated the relative abundance of subgingival plaque-specific bacteria in the salivary microbiota and examined a relationship between the abundance and severity of periodontal condition in patients with periodontitis. Four samples (subgingival and supragingival plaques, Subgingival plaque samples from patients with chronic periodontitis were exposed to light from a 7.3 mW Helium/Neon laser for 30 s in the presence and absence of 50 micrograms/ml toluidine blue O as a photosensitizer. Viable counts of various groups and species of bacteria … This chapter describes the cell and colony morphology, cultural and biochemical characteristics of oral microbes that are mainly isolated from subgingival plaques, including gram-positive bacteria of the genera Enterococcus, Eubacterium, Peptostreptococcus, and Propionibacterium, as well as gram-negative bacteria of the genera Bacteroides, Capnocytophaga, Eikenella, Fusobacterium, Helicobacter The survival of subgingival plaque bacteria in an amine fluoride-containing gel.

The presence and levels of 40 subgingival taxa were determined in 13.261 plaque samples using whole genomic DNA probes and checkerboard DNA‐DNA hybridization. supra- and subgingival plaque and aims to disrupt microbial bioﬁlms and reduce inﬂam-mation.
