Abstract

Certain strains of mesophilic Aeromonads like A.hydrophila, A.veronii biotype sobria and A.caviae when grown in broth containing 0.5% glucose, undergo growth inhibition concomitant with acetate accumulation. As these strains become nonviable after 24h, this phenomenon is termed suicide. We investigated suicidal strains of Aeromonas species as means of understanding animal virulence and enterophthogenicity. Non suicidal strains of A. Hydrophila showed and overall 88.8% lethality rate and non suicidal strains of A.veronii biotype sobria showed 83.3% lethality rate and was nil for its suicidal part. Of the two suicidal A.caviae strains tested, none were lethal. The present data suggest that the suicide phenomenon may explain strain specific [A.veronii biotype sobria, A.hydrophila] and species specific [A.caviae] virulence and enteropathogenicity.
