The chemical structure of prodigiosin has been unveiled.Serratia are capable of thriving in diverse environments, including water, soil, and the digestive tracts of various animals.S marcescens has a predilection for growth on starchy foodstuffs, where the pigmented colonies are easily mistaken for drops of blood.
In the gastrointestinal tract, the submucosa is the layer of dense irregular connective tissue or loose connective tissue that supports the mucosa, as well as joins the mucosa to the bulk of overlying smooth muscle (fibers running circularly within layer of longitudinal muscle).n the gastrointestinal tract, the submucosa is the layer of dense irregular connective tissue or loose connective tissue that supports the mucosa, as well as joins the mucosa to the bulk of overlying smooth muscle (fibers running circularly within layer of longitudinal muscle).
All four tissue types are present in the stomach. The stomach is lined with EPITHELIAL type cells (simple columnar). Beneath the epithelial cells there is CONNECTIVE type tissue.Beneath this you will find (smooth) MUSCLE cells. There is also NERVOUS type tissue present in the wall of the stomach (myenteric and submucosal plexus).eneath the epithelial cells there is CONNECTIVE type tissue.
