Antigenic Diversity of Infectious Bursal Disease Viruses

Avian Diseases, 1987
Statistically significant antigenic differences were detected among serotype I infectious bursal disease viruses (IBDV) using the virus-neutralization test. Eight serotype I commercial vaccine strains, five serotype I field strains, and two serotype II field strains were tested.

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 ...

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.

Comparison of vaccines against infectious bursal disease

Journal of Comparative Pathology, 1975
Abstract A comparative study was undertaken of 9 products from 7 different sources intended for use as vaccines against infectious bursal disease of chickens (IBD). A range of properties was found in laboratory tests for safety, efficacy and immunosuppressive effect.

Immunogenicity of Infectious Bursal Disease Viruses in Chickens

Avian Diseases, 1991
Cross-protective properties of infectious bursal disease viruses (IBDVs) were studied. Viruses represented different subtypes of serotype 1, including recently isolated viruses (variants), and a serotype 2 virus. Chickens were vaccinated at 3 weeks of age with inactivated vaccines containing 10(5), 10(6), 10(7), or 10(8) mean tissue-culture infectious ...

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 ...

Antigenicity, pathogenicity and immunosuppressive effect caused by a South American isolate of infectious bursal disease virus belonging to the “distinct” genetic lineage

Avian Pathology, 2019
Infectious bursal disease virus (IBDV) is the causative agent of a highly contagious immunosuppressive disease affecting young chickens. The recently described “distinct IBDV” (dIBDV) genetic lineage encompasses a group of worldwide distributed strains ...

Acute infectious bursal disease in poultry: A review

Avian Pathology, 2000
This review is focused on the acute form of infectious bursal disease (IBD) caused by very virulent IBD virus (vvIBDV). First described in Europe about 10 years ago, this new form of the disease has rapidly spread all over the world, causing dramatic losses; after a decade, it still represents a considerable threat to the poultry industry. Emergence of

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 ...
