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

Identification and Pathogenicity Evaluation of a Novel Reassortant Infectious Bursal Disease Virus (Genotype A2dB3)

Viruses, 2021
Infectious bursal disease virus (IBDV) is a non-enveloped, bi-segmented double-stranded RNA virus and the causative agent of a poultry immunosuppressive disease known as infectious bursal disease (IBD).

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.

TRIM25 is upregulated upon IBDV infection.

, 2021
(A) The RNA-seq analysis of host molecules from host defense upon IBDV infection compared to that of non-infected in DF-1 cells at 24 h p.i. (B and C). IBDV infection causes the mRNA levels upregulation of TRIM25 in DF-1 cells.

Apoptosis detection in embryonic chicken lymphoid tissues infected with attenuated very virulent infectious bursal disease virus (vvIBDV)

Brazilian Journal of Veterinary Pathology, 2009
We exposed chicken embryos at embryonating day (ED18) to a cell-adapted very virulent strain of IBDV (ca- vvIBDV) and original vvIBDV and examined the apoptosis from infected bursa of Fabricius (BF) and thymus organs.

Isolation, molecular characterization and pathogenicity studies of infectious bursal disease field virus isolates [PDF]

Journal of Veterinary Medical Research, 2008
This study was carried out to investigate the prevalence, molecular characterization and pathogenicity of field infectious bursal disease virus (IBDV) isolates. Nine isolates of IBDV were isolated from 13 naturally infected broiler flocks.

TRIM25 overexpression inhibits IBDV replication.

, 2021
(A-D) The influence of overexpression of pFlag-TRIM25 on IBDV replication. The DF-1 cells were transfected with 2μg pFlag-TRIM25 or pCAGGS at 24 h intervals and were infected with IBDV Gt strain at an MOI of 0.01.

STUDIES ON A RECENT IBD VIRUS FIELD VARIANT ISOLATE: (3) IMMUNOGENICITY OF THIS VARIANT STRAIN COMPARED WITH A CLASSICAL STRAIN IN BROILER CHICKENS [PDF]

Assiut Veterinary Medical Journal, 2005
SUMMARY   Three inactivated water–in–oil–in–water–emulsion infectious bursal disease virus (IBDV) vaccines were prepared from the Del/E related IBDV variant strain and a classical vvIBDV strain. Each IBDV strain were propagated for 6 serial passages in
