Infectious Bursal Disease Virus and Antarctic Birds

2009
The geographic isolation of the Antarctic continent coupled with the extreme climate has historically been assumed to protect the indigenous Antarctic wildlife from exposure to infectious agents found among animals in more temperate regions. However, with the number of tourists visiting the region more than doubling in the last 10 years (IAATO 2004 ...

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

Infectious Bursal Disease Virus and Proventriculitis in Broiler Chickens [PDF]

Avian Diseases, 2003
Acute necrotic proventriculitis is a naturally occurring disease of broiler chickens that causes proventricular rupture during routine evisceration. Although infectious bursal disease virus (IBDV) has been implicated, it has not been proven to be a direct cause of this disease.

Pathogenicity, Attenuation, and Immunogenicity of Infectious Bursal Disease Virus

Avian Diseases, 1996
An investigation was conducted in specific-pathogen-free chickens on the pathogenicity of bursa-derived and tissue culture-attenuated classic (STC) and variant (IN) serotype 1 strains of infectious bursal disease virus. The IN bursa-derived virus caused bursal inflammation, necrosis, and atrophy earlier than the bursa-derived STC virus.

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 ...

Agglutination of chicken lymphocytes by infectious bursal disease virus

Veterinary Microbiology, 1995
Four serotype 1 field strains of infectious bursal disease virus (IBDV) and one reference standard serotype 1 strain were tested for their ability to agglutinate peripheral blood lymphocytes of chickens. All the five strains agglutinated chicken lymphocytes. The agglutination was not inhibited by serotype 1 reference anti-IBDV serum.

Baculovirus Virions Displaying Infectious Bursal Disease Virus VP2 Protein Protect Chickens Against Infectious Bursal Disease Virus Infection [PDF]

Avian Diseases, 2011
Infectious bursal disease (IBD) is an acute and contagious viral infection of young chickens caused by IBD virus (IBDV). The VP2 protein of IBDV is the only antigen for inducing neutralizing antibodies and protective immunity in the natural host. In the current study, we have succeeded in construction of one recombinant baculovirus BacSC-VP2 expressing

Random cDNA Probes to Infectious Bursal Disease Virus

Avian Diseases, 1990
Viruses from three commercially available modified-live infectious bursal disease virus vaccines were propagated in tissue culture. Following this, a series of 32P-labeled probes was generated using the entire RNA genome as template for formation of randomly primed cDNAs.

Molecular Identification of Infectious Bursal Disease Virus Strains

Avian Diseases, 1997
Twenty-two infectious bursal disease virus (IBDV) strains were examined using the reverse transcriptase/polymerase chain reaction-restriction endonuclease (RT/PCR-RE) assay. A 394-bp fragment of the VP2 gene was amplified and tested for six different restriction enzyme sites.
