Infectious Bursal Disease Virus: Molecular Epidemiologic Perspectives and Impact on Vaccine Efficacy Against Avian Influenza and Newcastle Disease Viruses

Infectious bursal disease (IBD) virus (IBDV) is the causative agent of a highly contagious and immunosuppressive disease of chickens with huge economic losses to the poultry industry despite extensive vaccination. Analysis of isolated IBDV field strains from vaccinated birds would greatly improve the current immunization regimens and support the development of vaccines that offer better immunity. The study investigated the genetic...
