USPOULTRY: Researcher evaluates potential antibiotic alternative approaches for controlling salmonella in poultry
USPOULTRY and the USPOULTRY Foundation have announced the completion of a funded research project at the Ohio State University in which the researcher evaluated potential antibiotic alternative approaches for controlling salmonella in poultry.
The research was made possible in part by Simmons Foods and proceeds from the International Poultry Expo, part of the International Production & Processing Expo (IPPE). The research is part of the association's comprehensive research programme encompassing all phases of poultry and egg production and processing.
The project is known as "Genetic Identification and Screening for Potent Anti-Salmonella Gut Peptide Variant in Chicken: Avian Defensin, Beta Defensin 1 (AvBD1)".
According to a summary, Dr. Kichoon Lee, professor at the Ohio State University, completed the project that evaluated potential antibiotic alternative approaches for controlling salmonella in poultry.
Avian defensins have potent anti-bacterial activity. The expected long-term impact of the study was to help poultry breeders selectively breed chickens to have the most effective AvBD1 genotype; reduce the salmonella population within the chicken gut and ultimately produce a safer poultry product.
Although variations were identified in AvBD1 proteins among chicken populations, the in vivo and in vitro data did not show differences in anti-salmonella activities.
