SURVEY OF AEROMONAS HYDROPHILA IN THREE MARINE FISH SPECIES FROM NORTH WEST ARABIAN GULF, IRAQ

Abstract

This study preformed on 74 samples of marine water fishes (24 of Acanthopagrus lalus, 27 of platycephelus indicus and 23 of Cynoglossus arel). Which collected from north west Arabian Gulf of Basrah. All samples were examined for the presence of Aeromonas hydrophila in muscles. 24 isolates of Aeromonas hydrophila were obtained, (33.3%) from Acanthopagrus lalus, (44.4%) from platycephelus indicus, and (17.39%) from Cynoglossus arel. Then all isolates were examined for their ability to hemolytic activity as a virulence factor, the higher percentage of hemolytic activity isolates was found in Acanthopagrus lalus
