title: A toxigenic profile of Aeromonas hydrophila and Aeromonas sobria isolated from fish.
abstract: Forty strains of motile Aeromonas were isolated from healthy and diseased fish. These strains were identified as A. hydrophila or a A. sobria. It was found that only strains of A. hydrophila produced a dermonecrotic factor and two zones of hemolysis on blood agar. All the strains of A. sobria tested and 72% of the A. hydrophila were enterotoxigenic. Finally, we observed that only A. hydrophila strains could regularly produce hemolysin at 10 degrees C.
