Infectious Bursal Disease Virus (IBDV)

Recent Advances in Animal Virology, 2019
Infectious bursal disease virus (IBDV) is one of the most important viral pathogens of chickens. This virus causes great economic losses to the poultry industry due to factors like high mortality rates and poor growth performance of the affected chickens.

Commercial vaccines used in China do not protect against a novel infectious bursal disease virus variant isolated in Fujian.

The Veterinary Record, 2022
BACKGROUND Since 2018, atrophy of the bursa has been found among vaccinated chickens with high antibody titres against infectious bursal disease virus (IBDV) in Fujian, China, suggesting poor vaccine efficacy against circulating IBDV strains.

Modulation of macrophages by infectious bursal disease virus

Cytogenetic and Genome Research, 2007
Infectious bursal disease is one of the most important naturally occurring viral diseases of chickens worldwide. The causative agent, infectious bursal disease virus (IBDV), belongs to the family Birnaviridae. This viruscauses an acute, highly contagious and immunosuppressive disease in chickens.

Development of a recombinant VP2 vaccine for the prevention of novel variant strains of infectious bursal disease virus

Avian Pathology, 2020
Since 2017, novel variant strains of infectious bursal disease virus (nvIBDV) have been detected in China, while the current vaccines on the market against very virulent IBDV have limited protection against this subtype virus.

Identification of the Infectious Bursal Disease Virus in Mexico

Avian Diseases, 1972
An isolate (69-729) was obtained from birds showing clinical signs and lesions of infectious bursal disease (IBD). When inoculated into susceptible embryos it produced lesions characteristic of those produced by infectious bursal disease virus (IBDV). Its chloroform resistance, size, and cross-neutralization suggest that isolate 69-729 is an IBDV and ...

Infectious Bursal Disease Virus

2018
Infectious bursal disease is an acute, highly contagious, immunosuppressive disease that affects young birds causing important economic losses in the poultry industry. Its etiological agent is the Infectious bursal disease virus (IBDV), a non-enveloped bi-segmented double stranded RNA virus which belongs to the Genus Avibirnavirus from the Family ...

Molecular Detection and Differentiation of Infectious Bursal Disease Virus

Avian Diseases, 2007
Vaccination of hens, with the subsequent maternal immunity imparted to chicks, is the primary means of controlling infectious bursal disease virus (IBDV). Effective vaccination depends on rapid and accurate diagnosis of the subtype present in a flock because vaccines based on the classic subtype of IBDV can fail to protect against challenge with a ...

Infection and activation of bursal macrophages by virulent infectious bursal disease virus

Virus Research, 2005
In this study the effect of infectious bursal disease virus (IBDV) on bursal macrophages during the acute phase of the infection was examined. Specific-pathogen-free (SPF) chickens were exposed to virulent IBDV and bursal adherent cells were examined by immunohistochemisrty and RT-PCR for virus infection and by real-time quantitative RT-PCR (qRT-PCR ...

Localization of a VP3 epitope of infectious bursal disease virus

Virology, 1991
An immunodominant region of VP3, one of the two structural proteins of infectious bursal disease virus (IBDV strain 002-73), has been mapped by restriction site-specific deletion analysis and subcloning in Escherichia coli, followed by immunoblot analysis of the synthesized products.
