Bacteria in the human gut’s intestines are the most diverse in the human body and play a vital role in human health. In the gastrointestinal tract, dysbiosis manifests particularly during small intestinal bacterial overgrowth (SIBO), commonly caused by a decrease in the passage of food and waste through the gastrointestinal tract following surgery or other pre-existing conditions.

The species and diversity of the microorganisms may be related to the various levels of hormones during pregnancy. Vaginal flora can be transmitted to babies during birth. Vaginal dysbiosis can lead to vaginal infections like bacterial vaginosis which makes one relatively susceptible to sexually transmitted diseases.
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 ...
A new study has found that going on a juice-only diet for as little as three days can change people’s oral microbiome, with increased inflammatory bacteria and fewer beneficial bacteria found on ...
Many of the symptoms are due to malabsorption of nutrients due to the effects of bacteria which either metabolize nutrients or cause inflammation of the small bowel, impairing absorption. The symptoms of bacterial overgrowth include nausea , flatus , [ 5 ] constipation , [ 6 ] bloating, abdominal distension, abdominal pain or discomfort ...
[100] [98] The effects of the gut microbiota on the pharmacokinetics and bioavailability of the drug have been investigated a few decades ago. [101] [102] [103] These effects can be varied; it could activate the inactive drugs such as lovastatin, [104] inactivate the active drug such as digoxin [105] or induce drug toxicity as in irinotecan.

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.
