Infectious bursal disease virus: identification of the novel genetic group and reassortant viruses

Ветеринария сегодня, 2022
The results of the phylogenic analysis of the nucleotide sequence of the IBDV A and B genome segments have been presented. Traditionally the IBDV isolates are classified based on the phylogenic analysis of the hypervariable region of the VP2 gene.

Biochemistry and Immunology of Infectious Bursal Disease Virus

Journal of General Virology, 1988
Introduction. The aetiological agent of infectious bursal disease (IBD), IBD virus (IBDV), belongs to a new group of viruses referred to as ‘birnaviruses’ (Dobos et al., 1979), which has been characterized only recently (Brown, 1986). There are excellent reviews dealing with the clinical, pathological, serological and epidemiological aspects of IBDV ...

A proposed nomenclature for infectious bursal disease virus isolates [PDF]

Avian Pathology, 2018
Infectious bursal disease virus (IBDV) was initially identified in the USA. For decades, these viruses were not categorized using a typing system because they were considered to be antigenically and pathogenically similar. In the 1980s, a second major serotype, serotype 2, was found in turkeys.

PRODUCTION OF HYPERIMMUNE SERUM AGAINST INFECTIOUS BURSAL DISEASE VIRUS IN RABBITS [PDF]

Pakistan Veterinary Journal, 2004
The early and accurate diagnosis of infectious bursal disease requires known hyperimmune serum against the disease. In this study, an attempt was made to raise anti-infectious bursal disease virus hyperimmune serum in rabbits.

A protein with simultaneous capsid scaffolding and dsRNA-binding activities enhances the birnavirus capsid mechanical stability [PDF]

, 2015
Viral capsids are metastable structures that perform many essential processes; they also act as robust cages during the extracellular phase. Viruses can use multifunctional proteins to optimize resources (e.g., VP3 in avian infectious bursal disease ...

Homologous recombination is apparent in infectious bursal disease virus

Virology, 2009
Infectious bursal disease virus (IBDV) is a non-enveloped double-stranded RNA virus belonging to the Birnaviridae family. It shows substantial variation in the major antigen region of the viral capsid protein VP2, where a hypervariable region plays a key role in the virulence of IBDV and its epitope.

Structural and growth characteristics of infectious bursal disease virus [PDF]

Journal of Virology, 1976
The infectious bursal disease virus is not enveloped and has a diameter of 60 nm and a density of about 1.32 g/ml. It contains two pieces of single-stranded RNA with molecular weights close to 2 X 10(6). The capsid is made up of four major polypeptides with molecular weights of 110,000, 50,000, 35,000, and 25,000. The virus replicates in chicken embryo
