IntroductionSalmonella is a genus of Gram‐negative, rod‐shaped bacteria and a facultative intracellular human and animal pathogen belonging to the Enterobacteriaceae family (Galanis et al. ). Up to now, the species Salmonella enterica includes more than 2600 different serovars, which, despite their genome content similarity, it bring out very different diseases and distinct host immune responses (Issenhuth‐Jeanjean et al. ). Salmonella relies on virulence factors, many of which are clustered within five well‐characterized Salmonella pathogenicity islands (SPIs; Marcus et al. ). Salmonella also harbours virulence plasmids with variable size depending on the serovar (Ahmer et al. ). Whether virulence plasmids are required to trigger systemic disease and what is their involvement in the virulence of Salmonella strains is unclear and needs further investigation (Rotger and Casadesus ). Moreover, prophage‐like elements also carry virulence factors and, as new Salmonella genomes have been sequenced, their numbers are constantly rising (Wagner and Waldor ).Salmonella Typhimurium is worldwide surveyed serotype with well‐characterized genomes available for several different strains (Okoro et al. ). Nevertheless, the complete genome of S. Typhimurium strains in Brazil have become available very recently (Almeida et al. ; Panzenhagen et al. ), and limited information about their genome insight was revealed so far. In this context, S. Typhimurium
