Apoptosis detection in embryonic chicken lymphoid tissues infected with attenuated very virulent infectious bursal disease virus (vvIBDV)

Brazilian Journal of Veterinary Pathology, 2009
We exposed chicken embryos at embryonating day (ED18) to a cell-adapted very virulent strain of IBDV (ca- vvIBDV) and original vvIBDV and examined the apoptosis from infected bursa of Fabricius (BF) and thymus organs.

Rapid Spread of Novel Infectious Bursal Disease Virus Variant (Genotype A2dB1b) in the Near East and Persian Gulf Regions: Molecular Surveillance and Phylodynamic Reconstruction. [PDF]

Transbound Emerg Dis
Infectious bursal disease virus (IBDV) is one of the most impactful pathogens of poultry, with disease manifestations ranging from acute forms to subclinical but immunosuppressive infections. This heterogeneity, accompanied by a significant antigenic variability, is sustained by high mutation rates and frequent reassortments between the two genome ...

Isolation and genomic characteristics of the novel variant infectious bursal disease virus in China

Frontiers in Veterinary Science, 2023
The infectious bursal disease virus (IBDV) is a member of the viruses that can induce immunosuppression in chickens. In recent years, more and more IBDV-infected cases by the novel variant IBDV were reported in China, and it has been demonstrated that ...

First detection of natural co-infection with mutated very virulent IBDV (mvvIBDV) and novel variant IBDV (nVarIBDV). [PDF]

Poult Sci
Infectious bursal disease (IBD), a globally important immunosuppressive disease of poultry caused by infectious bursal disease virus (IBDV), continues to pose a substantial threat to the poultry industry. For the past three decades, very virulent IBDV (vvIBDV), associated with high mortality, have been the predominant epidemic threat.

Development of diagnostic tools for IBDV detection using plants as bioreactors [PDF]

AMB Express, 2020
AbstractInfectious bursal disease virus (IBDV) is the etiological agent of an immunosuppressive and highly contagious disease that affects young birds, thus causing important economic losses in the poultry industry. Multimeric particles with different architectures based on the capsid protein VP2 have been widely produced for different purposes.

Pathogenesis and Host Response to A3B4 and A3B2 Infectious Bursal Disease Virus Strains in Chickens. [PDF]

Transbound Emerg Dis
Recently, the identification of novel reassortants of infectious bursal disease (IBD) virus (IBDV) was reported. Interestingly, these strains competed with the previously dominant A3B2 lineage, becoming the prevalent lineage in Poland and disseminating to other countries in Europe.

VP2 of Infectious Bursal Disease Virus Induces Apoptosis via Triggering Oral Cancer Overexpressed 1 (ORAOV1) Protein Degradation

Frontiers in Microbiology, 2017
Infectious bursal disease (IBD) is an acute, highly contagious and immunosuppressive avian disease caused by IBD virus (IBDV). Cell apoptosis triggered by IBDV contributes to the dysfunction of immune system in host.
