Susceptibility of mammalian cell line for isolation of IBDV from clinical samples [PDF]

Brazilian Journal of Poultry Science, 2004
Susceptibility of chicken embryo related cells (CER) to non-classical IBDV was compared with Vero cells for the same purpose. It was used 20 bursal samples collected from clinical cases of IBDV, positive by histopathological evaluation. After three times

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 ...

IBDV-SSA, a novel molecular approach for the recovery of infectious bursal disease virus whole genomes from FTA cards [PDF]

Microbiology Spectrum
Infectious bursal disease (IBD), a highly contagious viral disease in young chickens, poses significant economic losses due to high mortality and immunosuppression. While IBD virus (IBDV) virulence is influenced by multiple genes, whole-genome sequencing

Host Combats IBDV Infection at Both Protein and RNA Levels

Viruses, 2022
Infectious bursal disease (IBD) is an acute, highly contagious, and immunosuppressive avian disease caused by infectious bursal disease virus (IBDV). In recent years, with the emergence of IBDV variants and recombinant strains, IBDV still threatens the ...

Development and Characterization of Monoclonal Antibodies Against VP3 Protein of Infectious Bursal Disease Virus. [PDF]

Transbound Emerg Dis
Infectious bursal disease virus (IBDV) causes an acute, highly contagious and immunosuppressive disease in 3–5‐week‐old chicken, called infectious bursal disease (IBD). Current vaccines targeting the hypervariable VP2 gene fail to provide cross‐protection against different IBDV strains, necessitating the development of novel diagnostic and preventive ...

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.

Efficacy of Single Dose Recombinant Herpesvirus of Turkey Infectious Bursal Disease Virus (IBDV) Vaccination against a Variant IBDV Strain [PDF]

Avian Diseases Digest, 2009
The use of viral vectors for transgenic expression of immunogenic proteins is a current trend in the poultry industry. The objective of this work was to assess the protection against the variant E of infectious bursal disease virus (IBDV), conferred by day-one vaccination with a commercial recombinant herpesvirus of turkey (HVT) vaccine (VAXXITEK ...
