TUCKER, Ga. — The U.S. Poultry & Egg Association and the USPOULTRY Foundation have announced the completion of a funded research project at the University of Georgia in Athens, Ga., in which researchers have developed a new vaccine candidate for infectious laryngotracheitis (ILT) to be applied in ovo.
Researchers at the University of Georgia, led by Dr. Maricarmen García in the Department of Population Health, found that deleting a gene from the ILT virus makes the virus less virulent and more useful as a vaccine.
The new vaccine gives good protection against ILT but is not safe enough to use in ovo in chicks with no maternal antibody against ILT. Continued efforts are being made to make the vaccine safer.
The project — Project #683: Designing a New Generation of Live Attenuated Infectious Laryngotracheitis Virus (ILTV) Vaccines for In Ovo Vaccination in Broilers — is part of the association’s comprehensive research program encompassing all phases of poultry and egg production and processing.
