WebThe flagellum is involved in the pathogenesis of some diseases and is antigenic (for example, antigen H). Examples of flagellate bacteria include Vibrio cholerae and Campylobacter jejuni, which use multiple flagella to propel themselves through the mucus lining of the small intestine to reach the epithelium and produce toxin. WebThese hair-like flagella are highly antigenic and, since the thorough studies of Craigie (1931), it is generally accepted that H-antigenic properties of certain bacteria are associated with the flagella. The nature of flagellar antigens was reviewed by Koffler and Smith (1971). Weibull (1949a, 1949b) showed that the flagella consist of fibrous ... dxlib setbackgroundcolorWebJan 2, 2024 · The classification of the 2000 or so different Salmonellae is based principally on the types of the O (LPS side chain) and H (flagellar) antigens.

WebMitogen-activated-protein-kinases (MAPK) acts as downstream signalling compounds, leading ultimately to PAMP -triggered immunity in which more than 900 genes are up-/down-regulated upon flg22 treatment. [citation needed] Pre-stimulation with a synthetic flg22-peptide led to enhanced resistance against bacterial invaders. [14] References [ edit] WebThe major antigens of E. coli are the K, H and O antigens. K antigens are components of the polysaccharide capsule or pilus-like proteins, H antigens are located on flagella, and O antigens compose the outer polysaccharide chains linked to the core lipopolysaccharide (LPS) of the bacterial cell wall of gram-negative bacteria.
