Researchers evaluate vaccination for bronchitis viruses

TUCKER, Ga. — USPOULTRY and the USPOULTRY Foundation announce the completion of a funded research project at the University of Georgia in Athens, Georgia, in which researchers evaluated a novel method to vaccinate for infectious bronchitis viruses. The research was made possible in part by an endowing Foundation gift from Fieldale Farms and is part of the Association’s comprehensive research program encompassing all phases of poultry and egg production and processing. A brief summary of the completed project is shown below. A complete report, along with information on other Association research, may be obtained through USPOULTRY’s website, The project summary is as follows.

Project #709: Infectious Bronchitis Virus Spike Protein-Pseudotyped Virus Particles for Vaccine Applications

(Dr. Brian Jordan and Dr. Mark Jackwood, University of Georgia, Athens, Georgia )

Dr. Brian Jordan and Dr. Mark Jackwood at the University of Georgia Poultry Diagnostic and Research Center recently completed a research project that evaluated the potential for pseudotyped vesicular stomatitis virus (VSV) particles carrying infectious bronchitis virus (IBV) spike proteins on their surface to be used as a vaccine for emerging variant IBVs. The objective was to determine if a novel vaccine production method could be used to shorten the variant-to-vaccine timeline and be efficacious at protection against the new IBVs. Data showed that the specific pathogen free chicks did not immunologically respond to the GA08 pseudotyped VSV particles.
