Abstract: A novel protein toxin named Aeromonas salmonicida exoenzyme T (AexT), which belongs to the family of ADP-ribosylating toxins, is disclosed as is a novel Calcium (or other cation concentration) dependent promoter of A. salmonicida. Also disclosed are diagnostic, preventative, and therapeutic techniques, including the preparation of traditional, recombinant, and improved bacterin vaccines based on AexT for inducing immunity against A. salmonicida infections.

Abstract: Disclosed is a newly identified and characterized type III secretion system in Aeromonas salmonicida. The invention also encompasses the use of components of the novel secretion system in immunoprotection against A. salmonicida infection, as well as other diagnostic and therapeutic uses thereof.

Abstract: The use of the 17 kDa outer surface lipoprotein (OspA) of Piscirickettsia salmonis, or its homologues, as the basis of, or part thereof, a recombinant vaccine for salmonid rickettsial septicaemia and other rickettsial diseases is disclosed. Surface antigens of the bacterial pathogen P. salmonis are characterized and an immunoreactive antigen, namely the 17 kDa outer surface lipoprotein OspA of P. salmonis, as well as the nucleic acid segment that encodes the OspA immunoreactive antigen, is identified and characterized. Diagnostic techniques including the use of hybridization probes and primers as well as the production of specific antigens and antibodies that may be used in immunization techniques for inducing immunity against P. salmonis and other rickettsial diseases are disclosed, as are the development of recombinant vaccines for SRS and other rickettsial diseases based on the 17 kDa lipoprotein OspA.
