This project assesses natural Salmonella resistance in 40 heritage breeds of chickens from four different small (non-commercial) hatcheries in Iowa. The investigators will identify breeds that resist colonization by Salmonella in their intestinal tracts after experimental infection; confirm that these breeds are resistant to an important array of Salmonella strains; and identify the genetic traits conferring the resistance. The results will have implications for human food safety.
Dr. Steve Carlson is an associate professor of molecular pharmacology in Iowa State University’s College of Veterinary Medicine – Department of Biomedical Sciences. He investigates the relationships between receptors, antibiotics, antibiotic resistance, and the virulence of bacteria enteropathogens such as Salmonella.
