Bacterial diversity in aphthous ulcers
Oral Microbiology and Immunology, 2007Introduction: Recurrent aphthous ulcers are common lesions of the oral mucosa of which the etiology is unknown. This study aimed to estimate the bacterial diversity in the lesions and in control mucosa in pooled samples using a culture‐independent molecular approach.Methods: Samples were collected from ten healthy individuals and ten individuals with

Bacterial Diversity in the Human Gut
2004Publisher Summary The human digestive tract is colonized by highly complex microbial ecosystem containing vast numbers of bacteria that could be assigned to several hundred bacterial species. Bacterial colonization of the gut is affected by a wide variety of host, microbiological, environmental and dietary factors, as indicated in the chapter.

Bacterial Diversity at High Temperature
1976An increasing number of organisms which are able to grow at high temperature has been isolated during the last few years.Our purpose in this paper is to analyze their properties from a microbiological point of view. The discussion will only deal with thermophilic procaryotes to the exclusion of blue-green algae (Castenholz, 1969) and actinomycetes ...

Bacterial diversity in agroecosystems
Agriculture, Ecosystems & Environment, 1999All life forms rely on bacterial processes for their survival. Bacterial diversity is greater than the diversity of any other group of organisms. Bacteria are responsible for diverse metabolic functions that affect soil and plant health. Nutrient cycling, organic matter formation and decomposition, soil structure formation, and plant growth promotion ...

A mouthful of bacterial diversity
Trends in Microbiology, 2000Extensive analyses of the bacterial flora living in our mouths have been carried out, primarily by cultivation in laboratory media. Using direct PCR amplification of 16s rDNA sequences present in tooth plaque, Relman and co-workers have now shown that many more bacterial species are present in this environment than was previously thought1xBacterial ...

Bacterial diversity in an industrial wastewater bioreactor
Applied Microbiology and Biotechnology, 2003Industrial wastewater bioreactors are potentially important sources of novel biocatalysts. However, the microbial populations in these bioreactors are not well characterized. The microbial community in an industrial wastewater bioreactor was surveyed by extracting DNA from a sample of activated sludge, followed by PCR amplification and sequencing of ...

Bacterial Diversity and Systematics
1994The proceedings of a symposium held under the auspices of the Federation of European Microbiological Societies, September 1993, in Granada, Spain, devoted to microbial identification. Such a topic could not be addressed without some reference to the enabling discipline of classification, but the ...

The Complexity of Microbial Diversity in Bacterial Vaginosis
New England Journal of Medicine, 2005The microbiologic cause of bacterial vaginosis has long eluded scientists, writes Sharon Hillier. The ecology of the vaginal microflora is influenced by several forces, thus challenging our understanding of the normal diversity of vaginal flora.

Bacterial Diversity in Freshwater
2017The tree of life, describing the evolutionary relationships among organisms, is totally dominated by bacteria. In a regular ecology textbook, the number of bacterial and Archaeal examples are, however, few. Microorganisms are in many respects understudied, and we do not yet know if they follow similar “rules” as other organisms: for instance, regarding

The Diversity of Bacterial Chemosensing
2018Bacteria have a continuous and urgent need to inform themselves about the chemistry of their surroundings. They must rapidly adjust their patterns of gene expression, their metabolic and transport functions, and their behavior to cope with every challenge and opportunity with which they are presented.
