Among infectious diseases most common diseases of bacterial origin: aeromonosis and Pseudomonas.
Aeromonosis.The causative agent is aeromonad – motile gram-negative bacteria p. Aeromonas (A. hydrophila, A. sobria) related to SEM. Vibrionaceae. Hits all the main types of pond fish (carp, white Amur, carp, crucian carp). The factors contributing to the development of fish are the sharp increase in water temperature, low fatness of the fish, dense planting, poor feeding, high content of organic matter, the trauma to the fish.
Aeromonosis is acute, subacute and chronic. The acute form is observed in the spring and summer and can be accompanied by mass death of fish (70%). The disease manifests itself in the form of serous-hemorrhagic inflammation of the skin and is characterized by edema, ekzoftalm, enlarged abdomen, aresenium scales. At autopsy in the abdominal cavity detect the exudates (clear, yellowish or bloody fluid), peritonitis, hemorrhagic inflammation of the intestines, degeneration of the internal organs (increase, discoloration, foci of necrosis).
