MICROBIOTA [10 records]

Record 1 2026-02-17

English

Subject field(s)
  • Genetics
  • Microbial Ecology
CONT

The term microbiome … includes not only the community of microorganisms, but also their "theatre of activity." The latter involves the whole spectrum of molecules produced by the microorganisms, including their structural elements (nucleic acids, proteins, lipids, polysaccharides), metabolites (signalling molecules, toxins, organic, and inorganic molecules), and molecules produced by coexisting hosts and structured by the surrounding environmental conditions. Therefore, all mobile genetic elements, such as phages, viruses, and "relic" and extracellular DNA, should be included in the term microbiome ...

OBS

The microbiome includes the microbiota.

French

Domaine(s)
  • Génétique
  • Écologie microbienne
CONT

De fait, le microbiome inclut tout le spectre des molécules produites par les micro-organismes, y compris leurs éléments structuraux (acides nucléiques, protéines, lipides, polysaccharides) et leurs métabolites (molécules de signalisation, toxines, molécules organiques et inorganiques).

OBS

Le microbiome comprend le microbiote.

The gastrointestinal(GI) tract of mammals is home to a large number and high diversity of microorganisms, including bacteria, archaea, viruses, and fungi, which together build a complex micro-ecosystem and shape the host's physiology[. Many] studies have focused on the role of bacteria in the gut microbiome while overlooking the intestinal fungi, partly because of the low abundance of the latter, as they account for only 0. 01–0. 1% of the whole community... However, accumulating evidence suggests that the fungal community, also referred to as the mycobiota, is indeed an important member of the microbiota, thereby requiring detailed characterization... the gut mycobiota has also been implicated in various pathologies, particularly in intestinal inflammation and infection.

Subject field(s)
  • Microbial Ecology
  • Plant Biology
CONT

Both the leaf and root microbiota contain bacteria that provide indirect pathogen protection, but root microbiota members appear to serve additional host functions through the acquisition of nutrients from soil for plant growth. Thus, the plant microbiota emerges as a fundamental trait that includes mutualism enabled through diverse biochemical mechanisms, as revealed by studies on plant growth–promoting and plant health–promoting bacteria.

CONT

Land plants host rich and diverse microbial communities in the thin layer of soil adhering to the roots, i. e., the rhizosphere, and within the root tissues, designated rhizosphere and root microbiota, respectively.

French

Domaine(s)
  • Écologie microbienne
  • Biologie végétale
CONT

Une partie importante du carbone fixé par les feuilles par la photosynthèse est secrétée par les racines dans la rhizosphère sous forme de molécules organiques. Ces exsudats racinaires représentent entre 5 à 30 % des produits de la photosynthèse [...] Ils nourrissent une importante communauté microbienne à l'interface sol-racine : le microbiote racinaire.

Subject field(s)
  • Microbiology and Parasitology
CONT

The oral microbiome contains over 600 species of microbiota. Under normal conditions the predominant phyla are Firmicutes, Bacteriodetes, Proteobacteria, Actinobacteria, and Fusobacteria. The most abundant bacterial genera in the oral microbiome are members of the genus Streptococcus, but Abitrophia, Gemella, Granulicatella, and Prophyromonas are also extremely common.

French

Domaine(s)
  • Microbiologie et parasitologie
CONT

La composition du microbiome oral est extrêmement dynamique en raison de la continuité de la cavité buccale avec l'environnement extérieur. De plus, la cavité buccale a de multiples fonctions essentielles qui affectent la croissance et l'activité bactérienne : manger, communiquer, déglutir, saliver [...]

Subject field(s)
  • Bowels
CONT

The intestinal microbes are taxonomically complex and constitute an ecologically dynamic community(microbiota) that has long been believed to possess a strong impact on human physiology. Furthermore, they are heavily involved in the maturation and proliferation of human intestinal cells, helping to maintain their homeostasis and can be causative of various diseases, such as inflammatory bowel disease and obesity... Through metagenomic analysis, it is now possible to comprehensively explore the genetic nature of the intestinal microbiome, the mutually interacting system comprising the host cells and the residing microbial community.

French

Domaine(s)
  • Intestins
CONT

Le microbiome intestinal est impliqué dans l’homéostasie et le fonctionnement du système immunitaire local. Un équilibre entre le microbiome intestinal et les mécanismes de défense est retrouvé normalement dans l’intestin des individus sains.

Fecal microbiota transplantation(FMT) re-establishes a balanced intestinal flora with resultant cure of recurrent Clostridium difficile infection(RCDI). FMT has also been used to treat other gastrointestinal(GI) diseases including inflammatory bowel disease(IBD), irritable bowel syndrome(IBS), and chronic constipation and a variety of non-GI disorders.

[...] la multirésistance aux antibiotiques est devenue un problème de santé publique majeur [...] Une [...] approche fait progressivement son chemin [...] Il s’agit de la greffe fécale, autrement dit du dépôt d’une flore intestinale saine dans un intestin malade pour éradiquer les bactéries pathogènes [...] Par cette méthode, on éviterait le problème des résistances aux antibiotiques et on reconstruirait rapidement la flore intestinale indispensable à la santé.

Our laboratory has demonstrated that mice can develop allergic airway responses to allergens if their endogenous microbiota is altered at the time of first allergen exposure. These experimental and clinical observations are consistent with other studies demonstrating that the endogenous microbiota plays a significant role in shaping the development of the immune system.

Water Microbiology: Water samples were collected from the Mir and processed using the Water Microbiology Kit. The kit contained a microbial capture device through which a water sample volume was processed. An ampoule containing nutrient growth medium was introduced into the microbial capture device to cultivate any microorganisms trapped on the filter. Unprocessed water samples were collected using the Water Sampler/Archiver. These archived samples and the processed water sample filters were returned for ground-based examination.

OBS

The objectives of this experiment were to characterize the microbiota of crewmembers, air, surface, and water microbes before, during, and after a long-duration mission aboard the Mir Space Station; to determine the exchange and distribution of microbes throughout the Mir Space Station; and to have operationally-ready hardware systems ready for the International Space Station(ISS).
