Genetic Insight into the Interaction of IBDV with Host—A Clue to the Development of Novel IBDV Vaccines

International Journal of Molecular Sciences, 2023
Infectious bursal disease virus (IBDV) is an immunosuppressive pathogen causing enormous economic losses to the poultry industry across the globe. As a double-stranded RNA virus, IBDV undergoes genetic mutation or recombination in replication during circulation among flocks, leading to the generation and spread of variant or recombinant strains.

IBDV particles packaged with only segment A dsRNA [PDF]

Virology, 2016
Multi-segmented dsRNA viruses have been suggested to utilize cis-acting elements in the plus-strand RNA to accomplish genomic RNA assortment during viral packaging. It is not clear if bi-segmented dsRNA birnavirus uses the same strategy. By applying a reverse genetic technique, we generated IBDV particles packaged with only segment A by co-transfection

A Single Vaccination of IBDV Subviral Particles Generated by Kluyveromyces marxianus Efficiently Protects Chickens against Novel Variant and Classical IBDV Strains [PDF]

Vaccines, 2021
Infectious bursal disease (IBD), caused by the infectious bursal disease virus (IBDV), is a highly contagious and immunosuppressive disease in chickens worldwide. The novel variant IBDV (nvIBDV) has been emerging in Chinese chicken farms since 2017, but there are no available vaccines that can provide effective protection.

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

Avian Diseases, 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 ...

Generation of a novel attenuated IBDV vaccine strain by mutation of critical amino acids in IBDV VP5

Vaccine
Infectious bursal disease virus (IBDV) is an acute and highly infectious RNA virus known for its immunosuppressive capabilities, chiefly inflicting rapid damage to the bursa of Fabricius (BF) of chickens. Current clinical control of IBDV infection relies on vaccination.

Molecular characterization of infectious bursal disease virus (IBDV): Diversity of very virulent IBDV in Tanzania

Archives of Virology, 2007
Nucleotide sequences of the VP2 hypervariable region (VP2-HVR) of 14 infectious bursal disease viruses (IBDVs) isolated in Tanzania from 2001 to 2004 were determined. Phylogenetic analysis showed that the isolates diverged into two genotypes and belonged to the very virulent (VV) type.

Protection of chickens, with or without maternal antibodies, against IBDV infection by a recombinant IBDV-VP2 protein

Vaccine, 2010
The use of avian herpesviruses (Marek's disease virus, MDV) as vectors to express the capsid protein of infectious bursal disease virus (IBDV) was well established, and its protection against IBDV challenge has been evaluated previously. However, there is little data about rMDV1 expressing the VP2 protein of IBDV protecting SPF and commercial chickens ...
