Infectious Bursal Disease (IBD) also known as Gumboro is an acute and highly contagious disease of young chickens, usually 3-6-week-old chickens. It is caused by a virus known as the Infectious Bursal Disease Virus (IBDV). This virus belongs to the avibirnavirus family and can survive for months in contaminated farms thereby constituting a big threat to the farms. Once the virus gain entry into the system of a bird, it affects the tissues of the immune system, especially the Bursa of Fabricius (BF) organ, resulting in immunosuppression and susceptibility to other infections, such as E. coli, Salmonella, Mycoplasma, coccidia, Marek’s disease and others. Till date, the chicken is considered the only species in which natural infection occurs.
TRANSMISSION
The mode of transmission is primarily through the fecal-oral route (occurs when bacteria or viruses found in the stool of one chick are swallowed by another). Feed, water and litter from an infected house remain infective for a long time. Also, the virus is resistant to some disinfectants. However, there is no evidence for egg (vertical) transmission of IBDV.
