A total of 120 fresh water fish samples were evaluated for the presence of Aeromonas spp. A. hydrophila, A. caviae, and A. veronii bv. sobria were isolated from the gills, intestines, livers, and skins of fish, and 78 isolated Aeromonas spp. strains were further examined for siderophore, hemolytic, protease, and pyrazinamidase activities and antibiotic resistance. Siderophore production was demonstrated in almost all of the A. hydrophila and A. caviae strains except for 2 strains of A. veronii bv. sobria. The strains identified as A. hydrophila and A. veronii bv. sobria were the stronger producers of hemolysin, whereas the A. caviae …
