Gumboro disease, also known as infectious bursal disease (IBD), is a highly contagious viral pathology that affects young poultry. It is caused by the infectious bursal disease virus (IBDV), a member of the avibirnavirus family. The disease primarily targets the bursa of Fabricius, a critical organ of the immune system in birds, leading to immunosuppression and increased susceptibility to secondary infections. Gumboro disease poses a significant threat to the poultry industry, causing high mortality rates and economic losses. In this comprehensive guide, we will delve into the causes, symptoms, and prevention strategies for Gumboro disease in poultry. We will explore the characteristics of the IBDV, its transmission, risk factors, clinical signs, diagnostic methods, and the importance of vaccination and biosecurity in controlling the disease. By understanding the intricacies of Gumboro disease, poultry farmers can implement effective measures to protect their flocks and mitigate the
