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.

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 ...

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.

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 ...

Infectious Bursal Disease Virus

1980
The purpose of this article is mainly twofold: to call attention to the infectious bursal disease virus (IBDV) as a member of a new and relatively unknown group of viruses and to point out a particular feature of IBDV replication, namely infection of lymphoid cells of the bursa of Fabricius (BF) as the main target organ and “viral bursectomy” as a ...

Immunosuppression induced by infectious bursal disease virus

Veterinary Immunology and Immunopathology, 1991
Immunosuppression caused by infectious bursal disease virus (IBDV) is of major interest because of the widespread occurrence of the infection in commercial chickens. Infection with IBDV at an early age significantly compromises the humoral and local immune responses of chickens. The cellular immune response is also compromised by apparently to a lesser
