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 […]
