Title: Modeling Salmonella transmission in swine
Salmonellosis is one of the most common bacterial food-borne illnesses. Farm animals, including cattle, pigs, and chickens are reservoirs for Salmonella. In recent years, the proportion of Salmonella resistant to several antimicrobial drugs (multi-drug resistant strains) has increased. Humans infected with multidrug re sistant strains are at greater risk of hospitalization and death compared to patients infected with susceptible strains. Prevention of human salmonellosis depends on decreasing the prevalence of infections in farm animal hosts as well as identifying and intervening along key transmission routes. This REU project will focus on developing mathematical models of Salmonella transmission in swine farms to better understand the factors that favor the transmission and the persistence of these multidrug resistant Salmonella in different farm environments.
