Salmonella spp. infection in piglets from Salmonella-positive breeding holdings

Abstract

The dynamic of pig salmonellosis during the first weeks of life is barely known. Studies suggest that Salmonella prevalence is very low as the percentage of shedders is low (<9%), but they are usually based on analyses of a small amount of fecal matter, which yield poor diagnostic sensitivity. Thus the true prevalence of infection is unknown, and therefore the potential of these young pigs to become shedders. This study shows results of a project aimed at assessing the level of infection in piglets from Salmonella-positive sow farms
