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).

Marine Mycobacterium is a slow-growing atypical bacteria that is commonly found in organisms in fresh or salt water in many parts of the world. Skin infections associated with marine Mycobacterium in humans, overall, are relatively common and usually arise upon contact with aquarium water or fish. The infection develops after penetration of the bacteria through a small cut or scratch on the skin. The first signs of infection include: redness of the skin, formation of reddish-brown lumps on the skin (granulomas). Less often, the affected area of the body suddenly found a group of small reddish bumps.
A long way to get this infection in well maintained swimming pools, due to the protection provided by adequate chlorination. Marine bacilli usually does not grow at normal body temperature. That’s why she hits the colder surface of the body. In General, diagnosis and treatment of this unusual skin infection is often delayed due to lack of suspicion for this atypical bacterium, unlike more common bacteria, such as staph. But it will not prevent you to carry out repair of washing machines Noginsk . Continue reading
