Generation and serological characterization of murine monoclonal antibodies against O antigens from Acinetobacter reference strains

O-antigen-specific monoclonal antibodies were generated against Acinetobact er strains from international type culture collections and characterized by enzyme immunoassay and Western and colony blotting. The antibodies aid in the further completion of an O-serotyping scheme for Acinetobacter and, due to their high specificity, are especially useful to all working with these strains.
