Potential Campylobacter vaccine identified through research
A potential vaccine for Campylobacterhas been identified in a research project at the USDA Richard B. Russell Agricultural Research Center in Athens, Georgia. The project was funded through the U.S. Poultry & Egg Association (USPOULTRY) comprehensive research program that encompasses all phases of poultry and egg production and processing.
No vaccines are currently available to prevent Campylobacter colonization of poultry. In the recently completed research project, researchers at the USDA Richard B. Russell Agricultural Research Center in Athens, Ga., purified proteins from Campylobacter and tested them for their potential use as vaccines. One particular protein, called FliD, showed particular promise. This protein is common to all 21 Campylobacter jejuni strains tested and is immunogenic in broilers. These characteristics make it a logical candidate for potential use as a vaccine. Future studies will focus on determining whether this protein can be used as a practical in ovo vaccine.
USDA scientists conducting the research included Hung-Yueh Yeh, Kelli Hiett, J. Eric Line and Bruce Seal.
A complete report that summarizes the Campylobacter research project, "Development of Campylobacter jejuni Proteins as in ovo Vaccines for Broiler Chickens,"along with information on other association research, may be obtained by going to the USPOULTRY website.
