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.

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 (IBDV)
2019Infectious bursal disease virus (IBDV) is one of the most important viral pathogens of chickens. This virus causes great economic losses to the poultry industry due to factors like high mortality rates and poor growth performance of the affected chickens.

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.

Reassortant infectious bursal disease virus isolated in China
Virus Research, 2008Infectious bursal disease virus (IBDV) is a bi-segmented, double-stranded RNA virus which belongs to the genus Avibirnavirus of the family Birnavirideae. In this study, we determined the complete nucleotide sequences of a reassortment IBDV strain TL2004 with segments A and B derived from attenuated and very virulent strains of IBDV.

Infectious Bursal Disease Virus
1980The 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 ...

Isolation of infectious bursal disease virus from Turkeys
Avian Pathology, 1979A virus, which is morphologically identical and antigenically related to two previously known isolates of infectious bursal disease (IBD) virus, was isolated from pooled faeces of 6-week-old turkeys with diarrhoea. It is concluded that this virus, designated TY89, is an isolate of IBD virus.

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

Molecular Detection and Differentiation of Infectious Bursal Disease Virus
Avian Diseases, 2007Vaccination of hens, with the subsequent maternal immunity imparted to chicks, is the primary means of controlling infectious bursal disease virus (IBDV). Effective vaccination depends on rapid and accurate diagnosis of the subtype present in a flock because vaccines based on the classic subtype of IBDV can fail to protect against challenge with a ...

Infection and activation of bursal macrophages by virulent infectious bursal disease virus
Virus Research, 2005In 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 ...
