Protective Efficacy of Intermediate and Intermediate Plus Infectious Bursal Disease Virus (IBDV) Vaccines Against Very Virulent IBDV in Commercial Broilers

Avian Diseases, 2005
The evolution of very virulent (vv) infectious bursal disease virus (IBDV) has led to significant economic losses in many poultry-producing areas. Despite vigorous vaccination strategies, IBDV has been difficult to control. The protective efficacy of IBDV vaccines is traditionally evaluated in specific pathogen-free (SPF) chickens.

Optineurin inhibits IBDV replication via interacting with VP1

Veterinary Microbiology
Avibirnavirus, specifically Infectious Bursal Disease Virus (IBDV), is a highly contagious pathogen that causes significant economic losses in the poultry industry. The polymerase protein VP1 of IBDV is critical to the viral life cycle, facilitating the synthesis of viral mRNA and the genome.

Development of a neutralizing monoclonal antibody to differentiate the predominant epidemic novel variant IBDV (nVarIBDV) from very virulent IBDV (vvIBDV)

International Journal of Biological Macromolecules
Chicken infectious bursal disease (IBD) is an acute, highly contagious, lethal, and immunosuppressive disease caused by the infectious bursal disease virus (IBDV). The newly emerged novel variant IBDV (nVarIBDV) and the continuously circulating very virulent IBDV (vvIBDV) are the two predominant epidemic strains that pose a threat to the poultry ...

Biological and physico-chemical properties of the infectious bursal disease virus (IBDV)

Avian Pathology, 1973
Some biological properties of an egg-adapted strain of IBDV, PV1, have been studied. By immunofluorescent staining the strain is serologically identical to another egg-adapted strain, MU2, and to three pathogenic strains of IBDV. All five strains do not react with antisera prepared against known avian viruses of various groups, including Reoviruses ...

Studies on Interferon Induction by Infectious Bursal Disease Virus (IBDV). I. Interferon Production in Chicken Embryo Cell Cultures Infected with IBDV

Avian Diseases, 1979
SUMMARY Two isolants of infectious bursal disease virus (IBDV) were found to induce interferon production in chicken embryo fibroblast (CEF) cell cultures. Both isolants were similar in one-step multiplication cycles and interferon-inducing properties. Interferon production was closely related to virus multiplication.

Molecular characterisation of IBDV isolates in Turkey revealed reassortant strains

British Poultry Science
1. Infectious bursal disease (IBD) is an acute, highly contagious viral disease of chickens caused by a virus (IBDV) which has a bi-segmented, double-stranded RNA genome. It has five viral proteins in its structure; the VP1 gene is encoded in segment B and the other four are in segment A.2.

Detection of infectious bursal disease virus (IBDV) genome in free-living pigeon and guinea fowl in Africa suggests involvement of wild birds in the epidemiology of IBDV

Virus Genes, 2008
Infectious bursal disease (IBD) virus (IBDV) serotype 1 is the causative agent of IBD, a highly contagious immunosuppressive disease of young chickens. In this study, we examined IBDV infection in apparently healthy 21 guinea fowls and 20 pigeons obtained in Tanzania and Zambia by virus neutralization test (VNT) and reverse transcription polymerase ...

Evaluation of the enzyme-linked immunosorbent assay for the detection of antibodies against infectious bursal disease virus (IBDV) and the estimation of the optimal age for IBDV vaccination in broilers

Avian Pathology, 2005
In order to evaluate the usefulness of the enzyme-linked immunosorbent assay (ELISA) in determining the optimal age for infectious bursal disease virus (IBDV) vaccination in broilers under field circumstances, the percentage of birds susceptible to vaccine at vaccination age was estimated in 12 flocks on the basis of ELISA titres in newborn chicks.
