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 ...
Various body parts have diverse microorganisms. Some microbes are specific to certain body parts and others are associated with many microbiomes. This article lists some of the species recognized as belonging to the human microbiome and focuses on the oral, vaginal, ovarian follicle, uterus and the male reproductive tract microbiota.
The microbiome is defined as a characteristic microbial community occupying a reasonable well-defined habitat which has distinct physio-chemical properties. The microbiome not only refers to the microorganisms involved but also encompass their theatre of activity, which results in the formation of specific ecological niches.
In fact, these are so small that there are around 100 trillion microbiota on the human body, [27] around 39 trillion by revised estimates, with only 0.2 kg of total mass in a "reference" 70 kg human body. [26] The Human Microbiome Project sequenced the genome of the human microbiota, focusing particularly on the microbiota that normally inhabit ...
An enterotype is a classification of living organisms based on its bacteriological ecosystem in the human gut microbiome not dictated by age, gender, body weight, or national divisions. [32] There are indications that long-term diet influences enterotype. [33] Three human enterotypes have been proposed, [32] [34] but their value has been ...
An enterotype is a classification of living organisms based on the bacteriological composition of their gut microbiota. The discovery of three human enterotypes was announced in the April 2011 issue of Nature by Peer Bork and his associates. [1] They found that enterotypes are not dictated by age, gender, body weight, or national divisions. [2]
The umbilicus, or navel, is an area of the body that is rarely exposed to UV light, soaps, or bodily secretions [8] (the navel does not produce any secretions or oils) [9] and because it is an almost undisturbed community of bacteria [10] it is an excellent part of the skin microbiome to study. [11]
[33] [34] The ways the microbiome influences human and animal health, as well as methods to influence the microbiome are active areas of research. [35] Research has suggested that microorganisms could be useful in the treatment of cancer. Various strains of non-pathogenic clostridia can infiltrate and replicate within solid tumors. Clostridial ...
