Preliminary structural analysis of infectious bursal disease virus by cryo-electron microscopy
浙江大学学报. 农业与生命科学版, 2019 In order to investigate the structure of infectious bursal disease virus (IBDV) and how the double-stranded RNA (dsRNA) segments of IBDV are organized inside its capsid and how the genome segments are transcribed and assembled, we first obtained IBDV ...

Modeling Infectious Bursal Disease Virus (IBDV) Antigenic Drift In Vitro
Viruses, 2022 Infectious bursal disease virus (IBDV) vaccines do not induce sterilizing immunity, and vaccinated birds can become infected with field strains. Vaccine-induced immune selection pressure drives the evolution of antigenic drift variants that accumulate amino acid changes in the hypervariable region (HVR) of the VP2 capsid, which may lead to vaccine ...

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 ...

Evaluation of secondary metabolites of herbal plant extracts as an antiviral effect on infectious bursal disease virus isolates in embryonated chicken eggs [PDF]
Veterinary World, 2021 Background and Aim: Infectious bursal disease attacks the poultry industry, mainly young chickens, causing immunosuppression, and death with high economic losses. This study aimed to evaluate the effects of the monoextract, diextracts, and triextracts of

Susceptibility of mammalian cell line for isolation of IBDV from clinical samples
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

Avian Pathology, 2003 Immunosuppression resulting from infectious bursal disease virus (IBDV) infection has critical health and welfare implications for birds, yet it is incompletely understood and largely overlooked as a measure of vaccine efficacy. The ability of a fowlpoxvirus recombinant (fpIBD1) containing the VP2 protein of IBDV to protect against IBDV-induced ...

IBDV particles packaged with only segment A dsRNA
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
