Background and Aim:Aeromonas hydrophila is causes disease in fish. This bacteria is found in water, water habitants, domestic animals and foods (fish, shellfish, poultry, and raw meat). Fish infected with Aeromonas hydrophila may have many different clinical signs. Organs commonly affected with this disease are include: skin, gills, kidneys, liver, spleen, pancreas, and skeletal muscle. Aeromonas hydrophila infection of fish is a zoonotic disease and can be spread from animals to man.Methods:The medium used for the isolation of A. hydrophila is TSA. Microscopic tests were done by staining Gram by observing the color and shape of bacteria was done. Biochemical test involved motile test, indol test, O/F test, and H2S test. Isolation of A. hydrophila was conducted on 30 samples of fish that were taken that showed pathologic conditions including hemorrhagic septicemia and tail or fin rot.Results:The results of the identification of the bacterial isolate showed negative staining Gram, motile, form rod, and biochemical test results are fermentative, positive oxides, positive glucose and negative indol.Conclusion:The bacterium Aeromonas hydrophila is one of the dangerous disease-causing bacteria in freshwater fish farming. Aeromonas hydrophila is a bacteria that can grow in the waters temperature of 20-30°C. Aeromonas hydrophila is pathogens because it only can cause disease in fish populations that are weak or as secondary infections when fish are infected with other diseases.
