1. What is infectious bursal disease (Gumboro, IBD)?

Infectious bursal disease is a highly contagious disease of young chickens (<17 weeks of age) in which the tissues of the immune system, and especially the bursa of Fabricius, are targeted resulting in immunosuppression and susceptibility to other infections, such as E. coli, Salmonella, Mycoplasma, coccidia, Marek’s disease and others. The "classic" form of IBD occurs worldwide and is endemic throughout the United States.

2. What causes infectious bursal disease?

Infectious bursal disease is caused by a virus called infectious bursal disease virus (IBDV), which belongs to the avibirnavirus family. The virus is very hardy, can survive in a wide variety of environmental conditions, and is difficult to effectively decontaminate.
