Researchers at Auburn University in Auburn, Ala., have developed a potential new vaccine for both Newcastle disease and infectious laryngotracheitis (ILT), according to USPOULTRY.

Joseph Giambrone of the Poultry Science Department at Auburn University created a new vaccine candidate for ILT.
A recombinant virus vaccine is constructed by inserting a gene from one virus into another virus so that the resulting recombinant virus will induce an immune response against both viruses. In this case, researchers inserted the gene for an important protein of ILT virus (glycoprotein B) into the B1 strain of Newcastle disease virus. The B1 Newcastle disease virus is one of the most commonly used live vaccines globally for controlling Newcastle disease.

Research to evaluate the safety and efficacy of the 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.
