Ibd Vaccine For Poultry

Infectious Bursal ( Gumboro) Disease is an acute highly contagious disease of young chicks (2-6 weeks old). It also affects chicks of 7-10 weeks in mild manner. Older birds do not develop clinical disease. The disease is associated with severe damage to Bursa of Fabricius in young chicks. This leads to defective immune systems, making chicks susceptible to many diseases like Ranikhet ( Newcastle) Disease inspite of vaccination. The disease spreads by contaminated feed, water and air. The incubation period is short (2-3 days). The affected chicks become dull, depressed, go off feed, have ruffled feathers and huddle in corners. Soon diarrhoea develops leading to progressive weakness & death in 5-6 days. It can affect 80% of the flock but kills about 2-10% chicks only. On postmortem, bursa is enlarged, oedamatous and yellowish. At times bursa show petechial or ecchymotic haemorrhages on mucosal surface. Occasionally, extensive haemorrhages through the entire bursa are observed. Pinpoint haemorrhages can be seen in muscles of breast, thighs and legs. Spleen is enlarged, caecal tonsil and thymus are hyperemic.

Description

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.

Features of Ibd Vaccine For Poultry

The vaccine contains live, low passage Infectious Bursal Disease Intermediate plus strain virus propagated in SPF chicken embryo fibroblast cell culture. The vaccine virus(serotype 1) successfully immunizes the chicks with maternal antibodies yet is nearly harmless to the Bursal tissue & confers quick immunity against virulent IBD virus. It is available in freeze dried form. The vaccine contains atleast ≥103TCID50 of virus per dose. 

The vaccine is available in 100, 200, 500 and 1000 dose vial.Bursine®-2 is a monovalent modified-live virus vaccine for the immunization of chickens against infectious bursal disease (IBDV) or Gumboro disease. Bursine-2 is particularly suited for use in flocks where maternal antibodies have interfered in active immunization using milder live virus vaccines.

Benefits of Ibd Vaccine For Poultry

Immune-complex IBD vaccines are prepared from live attenuated IBDV strains of the intermediate plus type, mixed in with specific anti IBDV serum to regulate the safety and release of the vaccine once the MDA levels of the bird are reduced. A correct balance between the IBD virus and the anti IBDV antibodies is of crucial importance for the efficacy and safety of these vaccines.

These vaccines have the ability to fully colonise the bursa and to protect against all field IBD viruses. The ‘take’ depends on the quality of application – the objective of a proper vaccine administration is not only to reach every chicken, but also to ensure that the full dose is received by each of them.The capacity of a vaccine strain to overcome MDA is one of the key advantages of the immune-complex vaccines. From the first day, the MDA levels will decrease. This decrease is variable according to the starting MDA level at hatch. The vaccine take occurs when the MDA level decreases to a point that allows the vaccine virus to be released and to reach the bursa of Fabricius. From this moment, the vaccine strain will replicate in the bursa of Fabricius, and the chicken will be immunized against any type of IBD virus (Active Immunity).

Precaution

  • Use entire contents of vial when first opened.
  • Burn vaccine containers and all unused contents.
  • Use only in states where permitted and on premises with a history of IBDV.
  • This product should be stored, transported and administered in accordance with instructions and directions.
  • Contains gentamicin as a preservative.
