IDEXX IBD Ab/IBD-XR Ab Tests
Detect more variant types of IBD viruses
Infectious bursal disease (IBD) or Gumboro disease is a viral disease affecting chickens at various ages. In the first two weeks of age, IBD variants can cause atrophy in the bursa and early immune suppression. From 3–6 weeks of age, classical IBD strains and very virulent IBD (vvIBD) can cause the bursa to become swollen and sometimes hemorrhagic. The bursa then quickly regresses to a small size, leading to suppression of the immune system or, in the case of vvIBD viruses, a higher percentage of mortality. Symptoms include anorexia, incoordination and depression. Affected birds are more susceptible to a variety of infectious agents, such as E. coli, Maternal antibody decay by virus neutralization, IDEXX IBD-XR Ab and IDEXX IBD Ab Tests Staphylococcus spp., Clostridium spp., and respiratory viruses, including live respiratory vaccines (rolling reactions). In addition, the clinical picture and immune suppression effect can be enhanced by chicken anemia virus (CAV) coinfections. Economic losses may approach 20% in an infected flock, and subsequent flocks may become infected from contaminated living quarters.
An assessment of immune status in the broiler breeders and/or day-old progeny, as well as serologic identification and definition at the processing plant, requires a measurement of antibodies to IBD in serum. Enzyme immunoassay systems have proven efficacious in the quantification of antibody levels to IBD, and facilitate the monitoring of immune status in large flocks, helping to establish baselines for a preventive medicine program on the farms.
