A probiotic is defined by FAO/WHO (2001) as a live organism which, when ingested in appropriate amounts, can confer a health benefit on the host.
In patients with chronic liver injury bacteria can escape the interior of the gut, reach the liver through the portal vein and trigger the development of cancer.
The entire intestinal microbiota weighs between
1,5 and 2 kg.
Some types of Diarrhoea are induced by harmful bacterial species or strains gaining predominance within the gut microbiota and thus obstructing the system of microbial checks and balances that usually guarantees proper intestinal functioning.
This term refers to a gut microbiota whose composition is out of balance, often due to illness, diet or antibiotics.
Intestinal microbes make use of our daily ingested food. The kind of diet has an important effect on the bacterial species and strains that populate our gut and dominate the gut microbiota composition.
Prebiotics are ingredients such as resistant starch and oligosaccharides that serve as ‘food’ for beneficial intestinal bacteria, thus modulating the composition or activity of the microbiota in a positive way.
The density of the gut microbial population grows along the intestinal tract and is highest in the large intestine. Particularly the caecum as part of this region hosts a large number of bacteria, and might, according to some experts, serve as a reservoir for bacterial regeneration after disruptions of the microbial balance.
Brain, gut and gut microbiota are tightly connected through a network of signaling pathways, running bottom-up as well as top-down and including the enteric nervous system, the vagus nerve and the spinal cord. This permanent bidirectional communication mutually affects gut, brain and gut microbiota.
The intestinal microbiota consists of 1014 cells (= bacteria) which is ten times more cells than there are in the human body.
