Random cDNA Probes to Infectious Bursal Disease Virus
Avian Diseases, 1990Viruses 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.

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.

Immunosuppression induced by infectious bursal disease virus
Veterinary Immunology and Immunopathology, 1991Immunosuppression 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

Pathogenicity, Attenuation, and Immunogenicity of Infectious Bursal Disease Virus
Avian Diseases, 1996An 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.

Agglutination of chicken lymphocytes by infectious bursal disease virus
Veterinary Microbiology, 1995Four 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

Molecular Identification of Infectious Bursal Disease Virus Strains
Avian Diseases, 1997Twenty-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.

Experimental Infection of Turkeys with Infectious Bursal Disease Virus
Avian Diseases, 1978Commercial turkey poults 3 to 6 weeks old were infected experimentally by eyedrop with an infectious bursal disease virus (IBDV) inoculum obtained from chickens experiencing clinical IBD. The IBDV was passed 6 successive times in poults in an attempt to increase its pathogenicity for turkeys.

The Immunodepressive Effect of Infectious Bursal Disease Virus in Chickens
Avian Diseases, 1974SUMMARY Infectious bursal disease virus (IBVD) depressed the humoral antibody response of chickens to various vaccines. The virus had that effect whether injected at the same time as vaccination or 4 or 7 days before. The depression was slightly greater when injection was 7 days before, and was most pronounced in chickens inoculated with IBDV when 6 ...

Characterization of Immunosuppression in Chickens by Infectious Bursal Disease Virus
Avian Diseases, 1979Chickens were infected with infectious bursal disease (IBD) virus in ovo or at different times posthatching to 6 weeks of age. The B- and T-cell responses in the lymphoid tissues and blood were examined sequentially to 8 weeks of age by using indirect immunofluorescence.
