Abstract
Infectious bursal disease (IBD) or Gumboro disease is caused by the
genera Avibirnavirus and the family Birnaviridae. For the last 66
years, this disease has been causing huge morbidity and mortality leading to
huge economic losses throughout the world. For
this review, we collected data from PubMed, CNKI, and Google Scholar, especially for the last decade. Articles containing
significant information were thrashed, extracted, and information being
presented.IBD virus (IBDV) could be attenuated, virulent (vIBDV), and veryvirulent
(vvIBDV).The host range is very wide including chickens, turkeys, Baltic
ducks, pigeons, speckled pigeons,
Herring gulls, ostriches, pied cordon
blues, laughingdoves,Antarctic penguins, and sparrows. The incubation period is very short, i.e., 2-3 days. The
virus occurs worldwide, and prevalence varies from 8 to 100%. IBDV has a great affinity with lymphatic tissues. This disease is
characterized by lesions of bursal hemorrhagic and inflamed lesions followed by
atrophy thus leading to immunosuppression. Effective vaccination programs and
strict biosecurity measures are
mandatory for its prevention and control. The starring role of wild birds in the
epidemiology of the IBD needs to be clarified as wild birds have indirect or
direct contact with commercial chicken rearing. We concluded that infectious
bursal disease is still a havoc in the poultry industry throughout the world.
Vaccination is a successful tool to control and inhibit IBD.
Vaccination failure could occur; however, farmers' education is necessary for
successful vaccination and disease prevention/control.
