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 ...
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.
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 ...
Lactobacillus species constitute a significant component of the human and animal microbiota at a number of body sites, such as the digestive system and the female genital system. [4] In women of European ancestry, Lactobacillus species are normally a major part of the vaginal microbiota .
In 2014, the Earth Microbiome project proposed a broad initiative to identify the diversity and importance of the microbiota in different ecosystems across the planet, including free-living microbiota (in water and terrestrial systems) and host associated-microbiota (associated with plants and animals).

Skin flora, also called skin microbiota, refers to microbiota (communities of microorganisms) that reside on the skin, typically human skin. Many of them are bacteria of which there are around 1,000 species upon human skin from nineteen phyla. [1] [2] Most are found in the superficial layers of the epidermis and the upper parts of hair follicles.
In the human body, microorganisms make up the human microbiota, including the essential gut flora. The pathogens responsible for many infectious diseases are microbes and, as such, are the target of hygiene measures.
Access to the previously invisible world opened the eyes and the minds of the researchers of the seventeenth century. Antonie van Leeuwenhoek investigated diverse bacteria of various shapes, fungi, and protozoa, which he called animalcules, mainly from water, mud, and dental plaque samples, and discovered biofilms as a first indication of microorganisms interacting within complex communities.
