Aeromonas hydrophila is a heterotrophic, gram-negative bacterium found in water, mainly in
warm climates. However, this bacterium is very resistant to low
temperature and other environmental changes, and has been
detected in fresh, salt, marine, estuarine and even chlorinated
water. It can survive in both aerobic and anaerobic
A. hydrophila is mainly associated with diseases of fish and
amphibians. In frogs, this bacterium causes red leg disease, in
which infected frogs can develop fatal internal hemorrhaging. In
fish it can cause ulcers, tail rot, fin rot, and hemorrhagic
septicaemia. Hemorrhagic septicaemia involves scale shedding and
lesions, hemorrhage in gill and anal areas, ulcers, exophthalmia
and abdominal swelling.
Outbreaks have been reported frequently in various regions of the world. For

Culture detection of the bacteria is not very effective because
culture sensitivity is low.
