Characterization of mouse monoclonal antibodies directed against Pseudomonas aeruginosa lipopolysaccharides

Mouse monoclonal antibodies that react with O-side chain specific, O-side chain cross-reactive, and core P. aeruginosa lipopolysaccharide determinants have been isolated. The monoclonals directed at O-side chain determinants are generally opsonophagocytic with human neutrophils and human complement. They also protect mice from intraperitoneal and intravenous challenge and protect in the burned rat model of infection.
