Abstract

The protective abilities ofEscherichia coli O and K immunity against intraperitoneal infection was compared in CBA mice immunized with formalin-killed bacteria. The K13 immunity achieved seemed somewhat more effective than the O6 immunity. This was also reflected in a slightly more rapid clearance of a liveE. coli O6K13 bacteria in K13-immunized animals than in those immunized with O6. However, the protection achieved afterE. coli O6K2 and O2K1 immunization was related more to O immunity than to K immunity.
