Hydropericardium-Hepatitis Syndrome, Angara Disease in broiler chicken Presentation Transcript

  • 1. Hydropericardium-Hepatitis Syndrome, Angara Disease in broiler chicken Dr.Kedar Karki
  • 2. Introduction
    • This condition was first identified in broilers in Pakistan in 1987. It spread rapidly in broiler producing areas in that country and the same or a very similar condition has been seen in North and South America. It affects mainly broilers and broiler parents in rear and has also been seen in pigeons.

    • It is a condition caused by an adenovirus, possibly in combination with an RNA virus and immunosuppression caused by Chick Anaemia Virus or Infectious Bursal Disease.
  • 4. Introduction
    • The disease is readily reproduced by inoculating birds with a bacteria-free filtrate of a liver extract from an affected bird. Mortality may reach 60% but more typically 10-30%.
  • 5. Signs
    • Sudden increase in mortality.
    • Lethargy.
    • Huddling with ruffled feathers.
    • Yellow mucoid droppings.
  • 6. Post-mortem lesions
    • Excessive straw-coloured fluid distending the pericardium (up to 10 mls).
    • Enlarged, pale friable liver and kidney.
    • Congestion of the carcase.
    • Lungs oedematous.

  • 13. Hydropericardium in a chicken. Excessive fluid is seen in the pericardial sac. Liver is swollen.
  • 14. Diagnosis
    • Lesions, histopathology, virology.
  • 15. Treatment
    • None. Good water sanitation (e.g. treatment of drinking water with 0.1% of a 2.5% iodophor solution) appears to be beneficial.
  • 16. Prevention
    • The condition typically occurs in areas of high poultry density where multi-age operation is traditional. Control of predisposing immunosuppressive diseases may help limit losses. Formalin-inactivated oil adjuvant vaccines are reported to be highly effective and are used in areas where the condition is endemic.
