TUCKER, Ga. – Researchers at North Carolina State Univ., Raleigh, NC, have evaluated a new vaccine to protect poultry flocks from two diseases, USPOULTRY and the USPOULTRY Foundation announced Jan. 15.

The new vaccine could protect chickens from infectious laryngotracheitis (LT) and Marek’s disease. LT is a highly contagious respiratory disease of chickens that can cause significant economic losses to the poultry industry. The new recombinant vaccine is made by inserting genes of infectious laryngotracheitis virus into a Marek's disease virus, according to USPOULTRY.

"The new vaccine shows potential advantages over existing vaccines," USPOULTRY said. "The results open a new avenue in the development of recombinant vaccines for use in poultry."
