Analysis of the function of D279N mutation of VP2 of infectious bursal disease virus

Journal of Integrative Agriculture, 2015
Infectious bursal disease virus (IBDV) is responsible for the highly contagious infectious bursal disease of chickens. Further understanding the gene-function is necessary to design the tailored vaccine.

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

Journal of Veterinary Medical Research, 2018
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.

Evasion of maternal antibody protection by an IBDV Argentine variant

Poultry Science
Infectious bursal disease (IBD) is a viral disease that affects the ability of chickens to produce humoral immune responses. One way to prevent the disease is the passage of maternally derived antibodies (MDA) from dams to offsprings via the yolk. Despite sanitary measures, which include immunization with genogroup 1 (G1) vaccines, infections with IBDV

Crude extract of bacterially expressed, infectious bursal disease virus VPX/VP2 proteins induces protective immune response to the virus in chickens

Archives of Razi Institute, 2014
Infectious bursal disease virus (IBDV) infects young chickens and causes serious lose to the poultry industry, worldwide. Previous attempts using purified bacterially expressed IBDV VP2 failed to elicit a protective immune response to the virus.

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 ...

Infectious bursal disease virus suppresses humoral immunity via blocking antibody affinity maturation in chickens

iScience
Summary: Blockade of antibody affinity maturation causes vaccination failure, yet whether pathogens exploit this process for immunosuppression remains poorly understood. Infectious bursal disease virus (IBDV) causes immunosuppression in chickens, but its
