The U.S. Poultry & Egg Association has announced results of two research projects as part of its research program on all phases of poultry and egg production.

In one study, researchers at the USDA’s Agricultural Research Service Poultry Microbiological Safety Research Unit at the Russell Research Center in Athens, Ga., attempted to find genetic biomarkers to identify campylobacter that can infect people. They discovered two genes that may serve as biomarkers to identify campylobacter isolates involved in human illness. Also, researchers identified a gene used to develop a fusion vaccine against campylobacter.

A separate study involved evaluating experimental vaccines to control Transmissible Viral Proventriculitis (TVP) in broiler chickens. Researchers at the North Carolina State University College of Veterinary Medicine Department of Population Health and Pathobiology in Raleigh, N.C., worked to develop a vaccine based on RII/3 virus VP2 protein. They found that an effective TVP vaccine will likely require construction with a vector such as the fowlpox virus or herpes virus of turkeys.
