Abstract first results. Salmonella sp. is responsible of human infections due to consumption of contaminated pork products. Carrier pigs introduce bacteria in the slaughter process. Italian situation is characterized by a high percentage of infected farms, and vaccination could have a decisive role in controlling infection. Unfortunately, none vaccine, licensed for swine, is available in Italy. The aim of our work is to describe data related to eficacy and safety of an attenuated S.Typhimurium vaccine, tested in experimental conditions, and an inactivated autogenous vaccine, tested in ield conditions. Attenuated strain is safe and protective, limiting fecal spread and organs colonization by virulent S.Typhimurium and it is also effective when intramuscularly administered or challenge is performed with S.Choleraesuis. Inactivated autogenous vaccine was administered in pregnant sows and their piglets of two farms. The results of this trial conirmed that sows vaccination, therefore antibody transfer with colostrum, is more protective than direct piglets vaccination.
