Virulence profiles of non-typhoidal Salmonella strains of avian, bovine and porcine origins

Abstract: Salmonella is a Gram-negative bacterium, and very diverse including more than 2500 different serovas based on Kauffman-White scheme. Salmonella is a common factor that causes food poisons in America and other countries especially in undeveloped countries where the food and water are unsafe. In this study, we focus on 8 virulence factors genes of NTS collected from 240 different samples of avian, bovina, and porcine origins. We hypothesize that NTS serovars undergoes a specific process of the host adaptation, during transmission from an animal to a human host. During the process of host adaptation, different types of selective pressures, imposed by environments (e.g. growth promoters) or the host (e.g. immune selective pressure) have a large impact on the population of NTS and possible play an important role in the host – pathogen interplay as well as the ability of NTS isolates to acquire antimicrobial resistance.
