Infectious Bursal Disease Virus
2018Infectious 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 ...

Antigenic Diversity of Infectious Bursal Disease Viruses
Avian Diseases, 1987Statistically 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.

Rocket Immunoelectrophoresis in the Diagnosis of Infectious Bursal Disease
Tropical Animal Health and Production, 2000The rocket immunoelectrophoresis (RIE) test was used for the qualitative detection and quantitative estimation of infectious bursal disease virus (IBDV) specific antigen in experimentally infected chickens and samples collected from suspected outbreaks.

Identification of the Infectious Bursal Disease Virus in Mexico
Avian Diseases, 1972An 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, 2007Infectious 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, 1975Abstract 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.

Acute infectious bursal disease in poultry: A review
Avian Pathology, 2000This 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

Immunogenicity of Infectious Bursal Disease Viruses in Chickens
Avian Diseases, 1991Cross-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 ...

Effect of Bursal Cell Number on the Pathogenesis of Infectious Bursal Disease in Chickens
Avian Diseases, 1987The pathogenesis of infectious bursal disease (IBD) in chickens neonatally chemically bursectomized (CB) by cyclophosphamide and subsequently inoculated with various numbers of bursal cells was examined. CB chickens inoculated with at least 62.5 X 10(6) bursal cells were as susceptible to IBD clinical manifestations (as determined by gross and ...

Infectious bursal disease (Gumboro disease).
Revue scientifique et technique (International Office of Epizootics), 2001Infectious bursal disease (IBD) (Gumboro disease) has been described throughout the world, and the socio-economic significance of the disease is considerable world-wide. Various forms of the disease have been described, but typing remains unclear, since antigenic and pathotypic criteria are used indiscriminately, and the true incidence of different ...
