Subgingival Distribution of Microorganisms
Composition of subgingival microbiotas has long been seen as being of primary importance in the etiology of periodontal diseases. Development of advanced molecular methods has improved our knowledge about the role of traditional periodontal pathogens as well as resulted in the recovery of novel pathogen candidates. Detection rates of these microorganisms vary considerably between geographical r...
متن کاملPlasmid content of some oral microorganisms isolated from subgingival plaque.
Eighty-five strains of bacterial species selected from the predominant cultivable dental plaque flora of patients with different periodontal pathologies were examined for their plasmid content. Microorganisms studied included: Actinomyces viscosus, A. odontolyticus, Bacteroides asaccharolyticus (B. gingivalis), B. melaninogenicus subspecies intermedius, and subspecies melaninogenicus, Capnocyto...
متن کاملDistribution of aldoxime dehydratase in microorganisms.
The distribution of phenylacetaldoxime-degrading and pyridine-3-aldoxime-degrading ability was examined with intact cells of 975 microorganisms, including 45 genera of bacteria, 11 genera of actinomyces, 22 genera of yeasts, and 37 genera of fungi, by monitoring the decrease of the aldoximes by high-pressure liquid chromatography. The abilities were found to be widely distributed in bacteria, a...
متن کاملDistribution of culturable microorganisms in Fennoscandian Shield groundwater.
Microbial populations in 16 groundwater samples from six Fennoscandian Shield sites in Finland and Sweden were investigated. The average total cell number was 3.7x10(5) cells ml(-1), and there was no change in the mean of the total cell numbers to a depth of 1390 m. Culture media were designed based on the chemical composition of each groundwater sample and used successfully to culture anaerobi...
متن کاملComputing the distribution of displacements due to swimming microorganisms
with n = N/V the number density of swimmers. This is nonzero (and might diverge) in the limit V → ∞, reflecting the cumulative effect of multiple swimmers. Note that this expression is exact, within the problem assumptions: it doesn’t even require N to be large. It is not at all clear that (4) leads to diffusive behavior, but it does [2–4]: the “support” of the drift function ∆(η, t) typically ...
