Distribution of Putative Virulence Genes in Aeromonas hydrophila and Aeromonas salmonicida Isolated from Marketed Fish Samples

I. Seethalakshmi, R. Subashkumar and P. Saminathan    

Abstract: The study sought a prevalence of virulent A. salmonicida and A. hydrophila in marketed fish samples by the molecular methods. A significant score of incidences (31.25 and 15.6% of A. salmonicida and A. hydrophila, respectively) were recorded and more diversification among the isolates based on their availability. It is important threat to the people who are consuming contaminated fish and other seafoods. Existence of putative virulence genes hlyA and aerA provides evidence for mutifactorial activities, which is encoded by the virulence factors like haemolysin and aerolysin and thus has the potential pathogenic. It was apparent that representatives of the four genotypes (hlyA+ aerA+, hlyA- aerA+, hlyA- aerA- and hlyA+ aerA-) were detected. The role in assessing Aeromonas influences on adverse public health is warranted
