O-antigens are composed of 10—25 repeating units of two to seven sugar residues and are processed by three mechanism of which the most common is Wzy O antigen polymerase dependent, followed by an ABC transporter dependent system, and the third mechanism, which involves a synthase dependent pathway Greenfield and Whitfield, by which the O-antigens are flipped across the outer membrane.
Each year, there are estimated to be million cases of ETEC in developing countries. There, the Dr adhesins induce the development of long cellular extensions that wrap around the bacteria, accompanied by the activation of several signal transduction cascades, including activation of PI-3 kinase.

coli O-groups and developed a typing. E. coli K waaL deletion mutants are unable to cap the lipid A-core and are therefore disrupted in the expression of O antigen at the cell. Escherichia coli strains are classified based on O-antigens that are components of the lipopolysaccharide (LPS) in the cell envelope.
