Infectious Bursal Disease (IBD): A Threat to Poultry

Infectious bursal disease (IBD) is a highly contagious and immunosuppressive poultry disease reported globally, affecting young broilers from 2-5 weeks of age.

Clinical signs of IBD include very virulent or subclinical manifestations, making vaccination in the hatchery a recommended practice to avoid clinical disease.

The disease is caused by Avibirnaviruses, which affect the lymphoid tissues, particularly the bursa of Fabricius, a crucial component in the maturation of the immune system cells during the embryonic period and the first 2 weeks of life after hatch.

Through innovation, a novel frozen IBD immune complex can help! stop the Gumboro cycle earlier than before, but vaccinating via subcutaneous or in-ovo routes remains a challenge in many hatcheries worldwide.
