Graphic depicting the human skin microbiota, with relative prevalences of various classes of bacteria. The human microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside, [1] [2] including the gastrointestinal tract, skin, mammary glands, seminal fluid, uterus, ovarian follicles, lung ...
The oral microbiota consists of all the microorganisms that exist in the mouth. It is the second largest of the human body and made of various bacteria, viruses, fungi and protozoa. [ 14 ] These organisms play an important role in oral and overall health.
The microbiome and host emerged during evolution as a synergistic unit from epigenetics and genetic characteristics, sometimes collectively referred to as a holobiont. [7] [8] The presence of microbiota in human and other metazoan guts has been critical for understanding the co-evolution between metazoans and bacteria.
The Human Microbiome Project (HMP) was a United States National Institutes of Health (NIH) research initiative to improve understanding of the microbiota involved in human health and disease. Launched in 2007, [ 1 ] the first phase (HMP1) focused on identifying and characterizing human microbiota.
In the context of genomics, the term human microbiome is sometimes used to refer to the collective genomes of resident microorganisms; [118] the term human metagenome has the same meaning. [117] Humans are colonised by many microorganisms, with approximately the same order of magnitude of non-human cells as human cells. [119]
In humans, gut microecology is the study of the microbial ecology of the human gut which includes gut microbiota composition, its metabolic activity, and the interactions between the microbiota, the host, and the environment. [3] Research in human gut microecology is important because the microbiome can have profound effects on human health.
The gastrointestinal microbiota has a direct effect on the human body's immune responses. meaning a regular microbiota is necessary for a healthy host immune system as the body is more susceptible to infectious and non-infectious diseases.
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.
