Infectious Bursal Disease rapid test
Gumboro rapid test
Fast disease detection with Gumboro rapid test
Infectious Bursal Disease (IBD), or Gumboro Disease, is a viral disease affecting young chickens. The disease has a worldwide prevalence. The target organ of the virus is the Bursa of Fabricius, an important organ in the young chickens’ developing immune system. The diagnosis cannot be made with certainty on the basis of clinical signs and necropsy alone. A quick and affordable way to do a pre-selection is the Gumboro rapid test.
Reports from IBD outbreaks come from all over the world. Morbidity is high and the mortality is variable depending of the age of the infected poultry, the production type of the poultry and the IBD strain. In susceptible birds mortality can be as high as 100%.The economic impact of an Infectious Bursal Disease Virus (IBDV) infection is twofold: direct mortality can be 40% and above. Also the suboptimal immune system has a negative impact on production efficiency. These negative effects of IBDV can be successfully controlled by vaccination and implementing solid biosecurity principles.
The disease can be clinical or subclinical and causes a lot of damage in both cases. The clinical disease is manifested by acute death, diarrhoea, lethargic and sick animals. The necropsy report consists of muscle bleeding, bloody or swollen bursas in the acute phase and small bursas at a later stage. Subclinical Gumboro's disease is sometimes difficult to observe. Frequently mentioned complaints are wet bedding, reduced technical results and slightly increased mortality are noticeable. The necropsy report consists of bloody or swollen bursas in the acute phase and small bursas at a later stage.
Gumboro rapid test
The diagnosis cannot be made with certainty on the basis of clinical signs and necropsy alone. A PCR test on bursa material (and genotyping if positive) is the way to find out if Gumboro field virus plays a role on the farm.
The Gumboro rapid test can be used to check the Gumboro vaccination. The rapid test should be positive three to five days after a vaccination with a live vaccine via drinking water. The rapid test is negative ten days after a successful vaccination. If the vaccination has been successful, the rapid test remains negative even after a field infection at a later time. When there are clinical or subclinical problems as a result of Gumboro, the rapid test becomes positive. After a positive rapid test, it is important to submit samples for a PCR test (and genotyping if positive). This will diagnose and identify the type of virus.
You can order de testkit with the diagnostics order form, articlenumber VLKIT117.
A quick (20 minutes) and affordable way to do a pre-selection is the Gumboro rapid test. You can perform the rapid test immediately after dissection and removal of the bursa. The chicken doesn’t have to be sent to a lab first and testing can often be done on-farm so you can save time and money.
