Abstract
In this case study of diagnosis
Aeromonas hydrophila
infected wild fish carp,
Carassiuegibelo
from Shut Al-Arab River
south of Iraq, Revealed that the incidence of
Aeromonas hydrophila
and cause blood poisoning
Aeromonas
(
MAS). The total number
of fish show clinical abnormalities
Aeromonas hydrophila
was isolated and identified are 20 fish. Samples were collected during the
summer season by using net electric fish.

Introduction
All populations of organisms, including aquatic
animals is limited partly or wholly in the ecosystem
(
Real, 1996). The prevalence of the disease in the ecosystem
is affected by many environmental factors, including
infectious and stressors (Nils Kautsky et al., 2000).
Aeromonas hydrophila
and other motile aeromonads
are among the most common bacteria in freshwater
habitats throughout the world, and these bacteria
frequently cause disease among cultured and feral
fishes.
Aeromonashydrophila
and other aeromonads are
among the most common bacteria in freshwater
habitats throughout the world. Genus
Aeromonas
includes
prominantmicrobiota
in freshwater reservoirs
where they together with other microorganisms act as
natural bio-filters and promote self purification of the
water body. The course of the disease usually runs in
an acute manner.
In natural situations, an infection with
Aeromonas hydrophila
,
fish probably a minor problem. Common disease
related stress conditions, Fish experts agree that fish
are easily stressed when mishandled, packed,
transported under poor conditions. Experimental
demonstration shows that fish in poor environments
due to unsatisfactory water quality such as high levels
of nitrite, low levels of dissolved oxygen, or high
levels of carbon dioxide (CO) are more vulnerable to
infection by
Aeromonas hydrophila.
Bacteria are everywhere, and occurs in most freshwater
environments. Can be found in the water column and in
the sediment than centimeter (Hazen, 1979). Aeromonads
mobile are adapted to environments that have a wide
range of conductivity, turbidity, pH, salinity and temperature
(
Hazen et al., 1978). Optimums temperature may
depend on the particular strain is under investigation,
but generally range from 25
℃
to 35 degrees Celsius
(
Meyer, 1970).

Fish Collecting
And wild populations samples were collected 20
weigh 50 g-80 g and measure 12 cm-25 cm from the
shut Al-Arab northern Iraq, using electric net fish
during the summer season. And the water temperature
was measured at the time of collection using a digital
thermometer. Samples directly kept into the containers
supplied with aerated river water, and transported to
the laboratory in the Department of fisheries
aquaculture and marine science centre Basrah
University. Fish exposed to clinical and examination
according to Austin and Austin (1999). And send a
copy of the clinical picture of Dr. Austin brain for
identification.
