Incidence of haemolysin-positive and drug-resistant Aeromonas hydrophila in freshly caught finfish and prawn collected from major commercial fishes of coastal South India

The incidence of Aeromonas hydrophila in freshly caught finfish and prawns from four major commercial fish landing sites of coastal South India was studied for a period of one year. Among 514 analysed samples of seafood (410 finfish and 104 prawn), 37% of them (37.3% of finfish and 35.6% of prawn) w...

Description
Summary:The incidence of Aeromonas hydrophila in freshly caught finfish and prawns from four major commercial fish landing sites of coastal South India was studied for a period of one year. Among 514 analysed samples of seafood (410 finfish and 104 prawn), 37% of them (37.3% of finfish and 35.6% of prawn) were contaminated with A. hydrophila. A total of 255 strains of A. hydrophila were isolated. Of the total isolates, about 78.4% of them were producers of haemolysin. All strains were resistant to bacitracin and all were sensitive to chloramphenicol. The results indicate that the strains originated from high-risk sources. The presence of A. hydrophila is an indication of marine contamination. The increasing presence of haemolysin-producing multiple drug-resistant A. hydrophila in fish and prawn may become a potential human health hazard.
