Abstract
Salmonellosis remains the most frequent foodborne zoonosis after campylobacteriosis (EFSA and ECDC 2017). The most frequent sources of human infection are food products of animal origin. Pork meat has been considered as one of the major sources (Bonardi 2017). Pigs colonized with Salmonella are usually asymptomatic healthy carriers (Rostagno and Callaway 2012) with varied levels and durations of fecal shedding (Ivanek et al., 2012). Thus, understand the mechanisms that result in more or less shedding may provide tools for control. Indeed, it has been demonstrated in other species that a minority of the infected individuals (super-shedders) are responsible of most of the transmission (Gopinath et al., 2014). In the frame of MoMIRPPC (EJP One Health), we wanted to evaluate the apparition of different shedding patterns among a pig population. Then, immune and microbiota analyses will be performed in order to identify markers link to the shedding status.
