Abstract

Salmonella enterica subspecies enterica is recognized as the etiological agent of Salmonellosis, a zoonotic disease transmitted in humans through contaminated food. In 2015, Salmonella s. p. was reported as the second bacterial agent responsible of gastro-enteritis in the European Union (EFSA, 2016). Pig consumption is considered as a major source of human Salmonella infections (Bonardi, 2017). Salmonella subspecies can be divided in 1530 serovars based on different epitopes and surfaces antigens. Associations exist between serovars and livestopchk species. In Pigs, in France, Salmonella Typhimurium, Derby and recently the monophasic variant of S. Typhimu-rium (vmST) are the most frequently isolated serovars (Denis et al., 2013; Kerouanton et al., 2013). The presence of monophasic variant of S. Typhimurium is also described in pigs in Europe (Bonardi et al. 2016).
