Bacteroides thetaiotaomicron is a Gram-negative, obligate anaerobic bacterium and a prominent member of the human gut microbiota, particularly within the large intestine.B. thetaiotaomicron belongs to the Bacteroides genus – a group that is known for its role in the complex microbial community of the gut microbiota.
Gut microbiota, gut microbiome, or gut flora are the microorganisms, including bacteria, archaea, fungi, and viruses, that live in the digestive tracts of animals. [ 1 ] [ 2 ] The gastrointestinal metagenome is the aggregate of all the genomes of the gut microbiota .
The bacteria and fungi live together in the gut and there is most likely a competition for nutrient sources present. [99] [100] Seelbinder et al. found that commensal bacteria in the gut regulate the growth and pathogenicity of Candida albicans by their metabolites, particularly by propionate, acetic acid and 5-dodecenoate. [98]
The microbiota comprises all living members forming the microbiome. Most microbiome researchers agree bacteria, archaea, fungi, algae, and small protists should be considered as members of the microbiome. [64] [1] The integration of phages, viruses, plasmids, and mobile genetic elements is a more controversial issue in the definition of the ...
Microbial metabolism is the means by which a microbe obtains the energy and nutrients (e.g. carbon) it needs to live and reproduce.Microbes use many different types of metabolic strategies and species can often be differentiated from each other based on metabolic characteristics.
Commensal gut microbes create a variety of metabolites that bind aryl hydrocarbon receptors (AHR). AHR is a ligand-inducible transcription factor found in immune and epithelial cells and binding of AHR is required for normal immune activation as the lack of AHR binding has been shown to cause over activation of immune cells. [1]
A recent report found temperature plays a major role in the amount of time the bacteria will persist in the environment, the life span increases with colder temperatures (0–4 °C). [23] "A new study has found that there is a three-way relationship between a type of gut bacteria, cortisol, and brain metabolites.
Human microbiota are microorganisms (bacteria, viruses, fungi and archaea) found in a specific environment. They can be found in the stomach, intestines, skin, genitals and other parts of the body. [1] Various body parts have diverse microorganisms. Some microbes are specific to certain body parts and others are associated with many microbiomes.
