Hydro pericardium means water in pericardium (the membrane surrounding the heart filled with water)
Also called as Angara, Hydro pericardium pulmonary edema, hepato nephrosis complex or inclusion body hepatitis etc.
First observed in Pakistan in 1987-88. Caused by Adenovirus strain K31/89 Broilers, layers as well as breeder birds are
susceptible birds. Birds shed virus in feces which is source of
infection

In Pakistan, first epidemic in late 1987 Sporadic cases recorded as early as 1985 Recorded in Iraq, Mexico, South and
Central America, Russia and Japan In India, first report in 1994

Highly pathogenic to day old chicks caused 80% mortality.
Most susceptible age is 3 to 5 weeks. No sex predisposition. Over crowding. Unhygienic and poor sanitary conditions. Presence of hepatotoxins and mycotoxins
in feed. Any type of stress in farm.

Externally it is very much difficult to diagnose it.
Chalky gray to bright light yellow mucoid droppings.
Sudden death. Jaundice signs in some birds Sudden mortality in 3rd week peaks in 4/5
week subsides in 5/6 week. Sometimes birds show signs of difficult
breathing.

Febrile carcass similar to gumboro and fowl typhoid.
Most important organ to be observed is heart Pericardium sac is distended with fluid. Mostly amount of fluid is 5-8 ml Color of fluid is clear of light yellow Non clotted fluid but gelatinizes on exposure to
air. Misshapen and flabby heart i.e. soft and cracks
on touching. Sub cutaneous and body fat of pale yellow color Enlarged, congested, pale and necrotic liver. Pale bone marrow death of bird occur due to
heart and liver failure.

½ cc inj. Preferable intramuscular on 15-17 or 21 day of age.
No treatment but supportive therapy can be done
Protein and fat content of diet reduced. Provide glucose in water. Feed grains only. Provide liver tonic medicines like hepamerz
or jetepar @ 2 teaspoon/gal water.

Adenovirus free chicks Proper cleanliness and disinfection of the
shed. Isolate sick birds. Keep all birds of same age. Hepatotoxin and mycotoxin free feed. Stress free environment.
Prevention and Control

Introduction Prevalence of diseasePredisposing factorsSymptoms Postmortum FindingsVaccination & Treatment Prevention & ControlOutbreak Management
No treatment. Vaccinate birds , repeat vaccine only if
previous vaccine was done 15-20 days before. Surviving birds are susceptible to E. coli,
respiratory infections, coccidiosis, IBD and ND so precautionary measures should be taken.
To avoid secondary infections specially respiratory infections use broad spectrum antibiotics after vaccination.
