Lipopolysaccharide is a component of the outer wall of Gram-negative bacteria cell wall. It is a substance composed of lipids and polysaccharides (glycolipids) with a molecular weight of more than 10,000 and a complex structure that varies between different groups and even strains. When it acts on other living cells such as humans or animals, it will show a variety of biological activities. The physiological effects of lipopolysaccharides are reflected by the presence of Toll-like Receptor (TLR)4 (TLR4) on the surface of the cell membrane of the host cell. Proteus mirabilis is a facultative anaerobic Gram-negative bacterium. Proteus bacteria of the Enterobacteriaceae family are pathogenic bacteria in human conditions, responsible for wound and burn infections as well as skin, eye, ear, nose, throat, urinary tract and gastrointestinal tract infections and bacteremia. Bacterial outer membrane lipopolysaccharides are considered to be important virulence factors of Proteus. It has been suggested that immune responses against LPS of Proteus mirabilis may play a role in rheumatoid arthritis. In addition, the abundance of Proteus mirabilis in the intestine may be related to obesity.
