Susceptibility of mammalian cell line for isolation of IBDV from clinical samples [PDF]

Brazilian Journal of Poultry Science, 2004
Susceptibility of chicken embryo related cells (CER) to non-classical IBDV was compared with Vero cells for the same purpose. It was used 20 bursal samples collected from clinical cases of IBDV, positive by histopathological evaluation. After three times

Identification and pathogenicity of a natural reassortant between a very virulent serotype 1 infectious bursal disease virus (IBDV) and a serotype 2 IBDV [PDF]

Virology, 2011
Infectious bursal disease virus (IBDV) causes an economically important, immunosuppressive disease in chickens. There are two serotypes of the virus that contain a bi-segmented double-stranded RNA genome. In December 2008, the first very virulent (vv)IBDV was identified in California, USA and in 2009 we isolated reassortant viruses in two different ...

Molecular genotyping of the infectious bursal disease virus (IBDV) isolated from Broiler Flocks in Egypt [PDF]

International Journal of Veterinary Science and Medicine, 2014
Re-emergence of highly virulent forms of IBDV has been the cause of significant economic losses. In present study, 52 bursa samples were assayed using reverse transcriptase-polymerase chain reaction (RT-PCR) for IBDV targeting VP2 gene. Out of the tested

Assessment of genetic, antigenic and pathotypic criteria for the characterization of IBDV strains

Avian Pathology, 2004
The aim of this work was the selection and comparison of representative infectious bursal disease virus (IBDV) strains. Nine strains of IBDV, isolated at different times and from different geographic regions of Europe and China, were characterized. Batches of all strains were prepared following standardized protocols and checked for the absence of ...

Susceptibility of Gecko Cell Line for Cultivation and Adaptation of Infectious Bursal Disease Virus as an Experimental Vaccine. [PDF]

Vet Med Sci
First successful cultivation of IBDV on reptile‐derived Z1 cells yields high‐titre virus and induces immunity in chickens. This scalable, egg‐free platform offers a promising alternative for vaccine production, leveraging evolutionary kinship between reptiles and birds for next‐generation poultry disease control.

Protection from infectious bursal disease virus (IBDV)-induced immunosuppression by immunization with a fowlpox recombinant containing IBDV-VP2

, 2010
Immunosuppression resulting from infectious bursal disease virus (IBDV) infection has critical health and welfare implications for birds, yet it is incompletely understood and largely overlooked as a measure of vaccine efficacy.

Enhancing MyD88 oligomerization is one important mechanism by which IBDV VP2 induces inflammatory response.

PLoS Pathogens
The inflammatory response is an essential component of innate immunity to defense against pathogens. Infectious bursal disease (IBD) is the most important immunosuppressive disease in chickens and is caused by the infectious bursal disease virus (IBDV ...

Modern methods of diagnosis and prevention of gumboro disease [PDF]

Науковий вісник ветеринарної медицини
Infectious bursal disease (IBD), also known as Gumboro disease, remains one of the most serious viral threats to modern poultry production, particularly in broiler and layer chickens. The disease specifically targets the bursa of Fabricius in young birds,

From nasal to basal: single-cell sequencing of the bursa of Fabricius highlights the IBDV infection mechanism in chickens

Cell & Bioscience, 2021
Background Chickens, important food animals and model organisms, are susceptible to many RNA viruses that invade via the nasal cavity. To determine the nasal entry site of the virus and clarify why avians are susceptible to RNA viruses, infectious bursal

Phylogenetic analysis reveals a correlation between the expansion of very virulent infectious bursal disease virus and reassortment of its genome segment B [PDF]

, 2006
Infectious bursa] disease virus (IBDV) is a birnavirus causing immunosuppressive disease in chickens. Emergence of the very virulent form of IBDV (vvIBDV) in the late 1980s dramatically changed the epidemiology of the disease.
