Aeromonas hydrophila is a bacterium found in warm climates. It is typically found in chlorinated, unchlorinated, estuarine, marine, salt and fresh water, surviving in anaerobic and aerobic environments. As an extremely resistant bacterium, aeromonas hydrophila is very hard to kill and can survive in temperatures as low as 4 degrees Celsius. Since the bacteria lives in aquatic environments, it is usually associated with diseases found in amphibians and fishes.

The aeromonas hypdrophila bacteria can be killed using a solution with 1% sodium hypochorite and 2% calcium hypochlorite.

Frogs, fishes and other amphibians can experience internal hemorrhage, ulcer, fin rot, rail rot, and hemorrhagic septicaemia – a condition that causes lesions, scale shedding, exhopthalmia, abdominal swelling and anal or gill hemorrhage.

This condition is caused by a bacteria called “aeromonas hydrophila”.
