  • Title: Genetic diversity among A-proteins of atypical strains of Aeromonas salmonicida.
    Author: Lund V, Mikkelsen H.
    Journal: Dis Aquat Organ; 2004 Nov 04; 61(3):257-62. PubMed ID: 15609880.
    Abstract:
    The virulence array protein gene A (vapA) encoding the A-protein subunit of the surface layer of 23 typical and atypical strains of Aeromonas salmonicida from salmonids and marine fish species were sequenced, and the deduced A-protein sequences compared. The A-proteins of the typical A. salmonicida ssp. salmonicida strains were shown to be identical, while amino acid variability was revealed among A-proteins of atypical strains. The highest amino acid variability appears to be in a predicted surface exposed region and is believed to result in antigenic differences among the atypical strains of A. salmonicida.
