Abstract
An improved method and vaccine is provided for the immunization of swine against infectious diseases caused by RTX toxin-secreting bacteria (e.g., porcine pleuropneumonia) which comprises administering to swine an effective amount of a live, immunizing, RTX toxin-secreting organism which induces in the swine a sufficiently high RTX toxin-neutralizing antibody titer to at least prevent clinical symptoms of the disease in the swine. For example, an intranasally administered, live, low virulence strain of A. suis (EM1) confers immunity upon swine against challenge with a virulent, disease-causing strain of A. pleuropneunmoniae.
