In health, bacteria are key components in the development of mucosal barrier function and in innate and adaptive immune responses, and they also work to suppress establishment of pathogens [1]. In disease, with breach of the mucosal barrier, commensal bacteria can become a chronic inflammatory ...
Some parts of nervous and circulatory systems also play a significant role in the digestion process. A combination of nerves, bacteria, hormones, blood and other organs of the digestive system completes the task of digestion. Let us have a detailed look at the human digestive system, its parts...

These images, made with two different techniques, show how the pathogenic bacteria attached to the lining of the gut of mice -- allowing them to out-compete the naturally occurring bacteria early in the infection. At left, an image made with fluorescence techniques, which shows pathogens in yel...

Recently, research on the human microbiome, especially concerning the bacteria within the digestive system, has substantially advanced. This exploration has unveiled a complex interplay between microbiota and health, particularly in the context of diseas
There is virtually no digestion in the large intestine, which contains only a small quantity of enzymes and an abundance of bacteria that cause carbohydrates to ferment and proteins to decompose. The products of the bacterial reactions are organic acids, carbon dioxide, methane, and hydrogen sulfide...

Protease is an enzyme that helps to break down proteins in the body to form amino acids, which then make them useful to the body and allow them to enter the bloodstream. Protease is useful in the body by helping to fight infection, parasites, and bacteria. It is used in the treatment ...
Small intestinal malabsorption allows fermentable nutrients to enter the colon, where bacteria generate osmotically active products that hold water in the lumen. Mucosal damage and inflammation lead to release of prostaglandin E2 (PGE2), which stimulates electrolyte secretion, and activation of mast...
