Scientists develop new vaccine to protect against two important diseases

Research project at North Carolina State University leads to new, stronger vaccine

USPOULTRY and the USPOULTRY Foundation announce the completion of a funded research project at North Carolina State University in Raleigh, N.C., that evaluated a new vaccine to protect again two important diseases. The project 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 by going to USPOULTRY's website. The project summary is as follows:

Project #676: Biological Characterization of a Serotype 1 Marek's Disease Virus-vectored Bi-valent Vaccine for Infectious Laryngotracheitis and Marek's Disease

(Dr. Isabel Gimeno, Dr. James Guy, Dr. Robert Silva and Dr. Henry Hunt; North Carolina State University in Raleigh, N.C.)

The research project, led by Dr. Isabel Gimeno and Dr. James Guy at North Carolina State University, evaluated a new vaccine candidate which could be valuable for protecting chickens against both Marek's disease and infectious laryngotracheitis. The new recombinant vaccine is a Marek's disease virus into which genes of infectious laryngotracheitis virus have been inserted. The new vaccine shows potential advantages over existing vaccines. The results open a new avenue in the development of recombinant vaccines for use in poultry.
