Infectious bursal disease virus: new method developed to screen vaccine candidates
Researchers at The Pirbright Institute have developed new tools and techniques to determine the breadth of immune responses produced by vaccines against different variants of infectious bursal disease virus (IBDV). Their study is published in the Journal of Virology. Eight IBDV genogroups have been identified and there are several variants of IBDV spreading in different […]
Variation in chicken interferon genes may account for susceptibility/resistance to viral pathogens
A study of different lines of chickens, known to be either more resistant or more susceptible to common poultry viruses, has uncovered dozens of variations in genes with a central role in the chicken immune response to infection. The findings, published in Animal Genetics, may point to genetic variations that determine birds’ response to infection, […]
IBDV VP4 protein dampens poultry immune response
Work carried out by scientists at The Pirbright Institute has revealed that differences in virulence between strains of Infectious bursal disease virus (IBDV) may be partly down to changes in the VP4 protein. Their findings, published in Frontiers in Cellular and Infection Microbiology, may help explain why very virulent (vv) strains cause high mortality rates […]
