Ibd Vaccine Poultry

Infectious bursal disease (IBD) is seen in young domestic chickens worldwide and is caused by infectious bursal disease virus (IBDV). Symptoms of the clinical disease can include depression, watery diarrhea, ruffled feathers, and dehydration. Depending on the IBDV strain and presence of maternal immunity, the disease can also present as a clinical or subclinical disease in young chicks. For both clinical and subclinical forms of the disease, all pathogenic IBDVs cause lesions in the bursa of Fabricious. The cloacal bursa can become enlarged, with a yellowish colored transudate on the surface. Hemorrhages on the serosal and mucosal services are sometimes observed. Atrophy of the bursa, which includes the loss of B-lymphocytes, occurs approximately 7-10 days after infection. Immunosuppression is directly related to this loss of B-lymphocytes, but immunosuppression and related secondary infections are typically seen in birds that recover from the disease. Severity of the immunosuppression depends on the virulence of the infecting virus and age of the host.

Lesions

At necropsy, the lesions seen will depend on the strain of IBDV. For strains that cause a clinical disease, the cloacal bursa is swollen, edematous, yellowish, and occasionally hemorrhagic, especially in birds that died of the disease. Strains of vvIBDV cause similar cloacal bursa lesions, and congestion and hemorrhage of the pectoral and leg muscles can also occur. Some IBDV strains can cause atrophy of the cloacal bursa without the appearance of gross lesions in that organ. Chickens that have recovered from IBDV infections have small, atrophied, cloacal bursas due to the destruction and lack of regeneration of the bursal follicles.

Features of Ibd Vaccine Poultry

Vector IBD vaccines are constructed from a genetically engineered virus (the vector) whose genome contains a gene from a specific IBDV (the donor) encoding for the VP2 capsid protein. As of today, the Herpes Virus of Turkey (HVT) is mainly used as a vector. Although these vaccines provide proper protection against clinical signs of IBDV, they do not fully colonise the bursa, leading to field IBD viruses being able to enter and replicate in the bursa.

Using a vector vaccine, the immunity does not come from replication of a complete virus, triggering all the arms of the immune system (‘complete’ immunity), but essentially from an antibody response to the VP2 antigen of the IBD virus expressed by the recombinant HVT vector. That way, when considering protection against the Gumboro virus, the useful part of the immune response is mostly of the humoral type. Protection against Gumboro Disease comes from the expression of the VP2 by rHVT-VP2 -infected cells, and is a much slower process. Onset of immunity against IBD requires much more time than for MD.
