Identifying 'heritage' chickens that naturally resist Salmonella contamination [DPS2013-01]

Project Description: 

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.
