New vaccine developed for Newcastle, ILT diseases

Must read

TUCKER, Ga. — Dr. Joseph Giambrone with the Poultry Science Department of Auburn University has completed a research product in which he created a new vaccine candidate for infectious laryngotracheitis (ILT), a disease of chickens.

The research was funded by the U.S. Poultry & Egg Association and the USPOULTRY Foundation with an endowing Foundation gift from Pilgrim’s.

The new vaccine was created by inserting a gene from ILT virus into the B1 Newcastle disease vaccine, which is commonly used in broilers at one day of age.

The overall objective of the research project was to develop a recombinant vaccine that is efficacious and safe for use in controlling ILT.

Research to evaluate the safety and efficacy of this new vaccine candidate is continuing.

Studies in birds will determine whether the vaccine can safely induce immunity against both Newcastle disease and ILT in day-old broiler chickens. In addition, its safety and efficacy will be compared to the currently used recombinant and live chicken-embryo-origin vaccines.

The research project is part of USPOULTRY’s comprehensive research program encompassing all phases of poultry and egg production and processing.
