Shielding of Escherichia coli outer membrane proteins as receptors for bacteriophages and colicins by O-antigenic chains of lipopolysaccharide.
The accessibility of several outer membrane proteins for bacteriophages and colicins in isogenic smooth and rough Escherichia coli strains was investigated. The results show that O antigen carrying lipopolysaccharide is able to prevent access of all phages and colicins tested to their outer membrane protein receptors.
