ARS:  Athens, Ga. - Poultry disease is an international issue and developing animals resistant to disease may be one of the long-term solutions.  University of Georgia researchers Steven Stice and Franklin West in the College of Agricultural and Environmental Sciences and Claudio Afonso at the Southeast Poultry Research Laboratory of the U.S. Department of Agriculture's Agricultural Research Service have spent the last four years gathering data that could make the process a reality.

The team used a technology platform called shRNA???single strands of RNA that fold back on themselves???to selectively stop the production of nucleic acids that cause disease, such as the Newcastle disease virus.  Dr. Afonso was responsible for the design of the products used to reduce virus replication (gene specific shRNA) and together with his team developed methods to conduct the challenges with virulent viruses and evaluate the results.  Initial experiments were conducted at UGA and final testing and evaluation was done at the BSL3 facilities of U.S. National Poultry Research Center in Athens.

The research team's tooling process for enhancing disease resistance, published recently in the Journal of the International Alliance for Biological Standardization, is potentially a much better way of disease protection than vaccination because it introduces permanent genetic resistance that is transmittable to a bird's offspring. In contrast, many vaccines provide protection for a given period of time and must be re-administered periodically.

Multiple types of animals and disease could be targeted. This technology could also be applied to avian influenza and swine flu.  To read the full story, "Delayed Newcastle disease virus replication using RNA interference to target the nucleoprotein," is available at www.sciencedirect.com/science/article/pii/S1045105615000275.
