Histopathological studies of experimental Aeromonas hydrophila infection in blue tilapia, Oreochromis aureus

الملخص EN

Blue tilapia, Oreochromis aureus, was experimentally infected with Aeromonas hydrophila, a bacterium that damages the gills, liver, and intestine, resulting in histopathological changes in the infected organs.

Our histopathological study showed an aggregation of hemocytes with cell necrosis in gills ; a massive aggregation of hemocytes and pyknotic nuclei in the hepatopancreas; and a lower rate of hemocyte aggregation in the digestive system of the infected fish.
