Infectious bursal disease, IBD (also known as Gumboro disease, infectious bursitis and infectious avian nephrosis) is a disease of young chickens caused by infectious bursal disease virus (IBDV). The disease is characterized by immunosuppression and mortality generally at 3 to 6 weeks of age.
Transmission:
The mode of transmission is primarily through the fecal‐oral route. The disease is mainly controlled by rigorous sanitary measures and vaccination through the use of either live or killed vaccine. Infectious bursal disease virus is very stable and has been reported to resist many disinfectants at certain concentrations and or conditions.
Symptoms:
The disease may appear suddenly and morbidity typically reaches 100%. In the acute form birds are prostrated, debilitated and dehydrated. Infected birds produce a watery diarrhea and may have swollen feces-stained vent.
