Escherichia coli Antigen (E. coli Antigen)

Escherichia coli (E. coli) antigens are surface molecules on E. coli bacteria that elicit immune responses. Key antigens include the O antigen (lipopolysaccharide), K antigen (capsular polysaccharide), H antigen (flagellar protein), and fimbrial antigens. These antigens are crucial for bacterial identification, serotyping, virulence, and host-pathogen interactions. They are targets for diagnostic antibodies and vaccine development.

Antibodies bind to antigens, neutralizing the bacteria or marking it for destruction by the immune system. Vaccines stimulate the production of antibodies.
