IBH in Poultry Dr. KHM
Dr. Md. Kumrul Hassan from VSD Square Pharmaceuticals discusses challenges in poultry health, including disease emergence, antibiotic resistance, and specific issues like Inclusion Body Hepatitis (IBH). IBH predominantly affects young birds, leading to high mortality and requires critical biosecurity measures for prevention. The document also emphasizes the importance of supportive care and specific treatment options while noting that avian adenoviruses have no public health implications for humans.

- 2. Immunity, Health &Production 2 • Consumer confidence, product quality & safety, emergence & re- emergence of diseases, antibiotic resistance - major challenges to current situation and strategic future It is essential to know that chickens are not susceptible to intranasal infection by the SARS-CoV-2 (COVID-19) virus.
- 3. Inclusion Body Hepatitis Acuteinfectious disease characterized by typical hydropericardium, severe anaemia, necrotic hepatitis and high mortality Also called as Angara, Hydropericardium syndrome, hepato nephrosis complex, Litchi Heart disease etc 3 Introduction
- 4. Adenovirus strain K31/89 “InclusionBody” - little dark dots in nucleus of liver cells under microscop “Hepatitis” - liver swells and become discoloured. “Hydro pericardium” - water in pericardium 4 Introduction
- 5. • 1st describedin USA (1963) than Canada, UK, Australia, Italy, France, Ireland, Pakistan (1987) • Affected birds may not exhibit any clinical signs except sudden heavy mortality • Morbidity 1 - 10%, Mortality 15 - 60% 5 Epidemiology • Mostly affects young birds between 2 - 5 weeks of age and occasionally layer and breeder pullets also
- 6. 6 • Transmitted bothvertically and horizontally • Course of 9- 15 days as infected birds remain carriers for a few weeks. • Resistant to environmental factors and easily transmitted by a mechanical route. • Immune system damage from IBD can help to push these broiler flocks into full-blown IBH disease. Adenoviruses are very common in the poultry environment Transmission
- 7. Signs - symptoms,PM lesions, ELISA, Agar Gel diffusion , Immunoelectrophoresis, PCR test helps to specific diagnosis Symptoms • Depression, Anorexia & Inappetance • Ruffled feathers, Pallor comb & wattles • Chalky gray to bright light yellow mucoid droppings • Anemia and dehydration may develop secondary to hemorrhagic enteritis • Sometimes skin become icteric 7
- 8. Typical viral particlescan be detected from feces, liver, spleen, kidney, or other affected tissues. Post-Mortem Lesions • Febrile carcass similar to gumboro and fowl typhoid • Liver swollen, yellow, mottled with petechlae and Ecchymoses • Kidneys enlarged, pale and mottled with multiple hemorrhages • Blood thin and bone marrow pale • Pericardium sac is distended with fluid. 8
- 9. 9 • Vaccination (N/Ain BD) • Strictly maintain biosecurity • Good water sanitation • Eggs of broiler parent flocks, affected progeny, should not be used for hatching. • Treatment of drinking water with 0.1% - 2.5% Viodin Vet solution appears to be beneficial. Supportive care: Limit stress: Call veterinarian Control & Prevention
- 10. Avian Adenoviruses donot naturally infect mammals and therefore no public health implications exist. Use Antiviral Preparations Andopan Use NephroImmunomodulators Nephrocare Use Liver tonic with Choline chloride, except B1 or Herbal Preparation Toxol Liquid / Digestim Avoid giving Sulpha drug Use Amprium* 10 Balanced Feed Supply grain with amino acid & Low Protein Treatment

Editor's Notes
- #3 Poultry immunity, health, and production etc are future growth of the poultry industry.
- #4 adenovirus ( mostly serotype 4 & 8) The adenovirus is a non-enveloped icosahedral, The nucleic acid is linear, ds DNA These viruses are capable of producing the disease without the immunosuppressive effects of associated viruses such as IBD or other immunosuppressive agents. pericardium (membrane surrounding the heart filled with water) The disease was first described in young broilers in Angara Goth, Pakistan, during the year 1987.
- #5 Many types of bacterial and viral infection can cause the liver to swell, but the dots or “inclusion bodies” tell the pathologist that adenovirus is involved.
- #6 In natural outbreaks, the affected birds may not exhibit any clinical signs (Jaffery , 1988) except sudden heavy mortality (Ravikumar et al. , 1997). Mortality rates in various outbreaks range from 15- 60% (Asrani et al. , 1997). mostly affects young birds between 3 and 6 weeks of age ( Niazi et al. , 1989 ) and occasionally layer and breeder pullets also
- #7 Once a broiler farm has experienced IBH, the virus may become resident on the farm.
- #11 ) stop feed for 36 hours & give grains with salt 400 gm/qt plus Amino acids. Plus Calcium @ 500ml/1000 birds. Logic behind giving this formula is the kidney & liver are swollen & they may not digest proteins so giving grains will give some relief.
