In our study, all 15 Salmonella strains present virulence genes related to the host invasion, host recognition, and colonization, such as invA, pefA, prgH, spaN, tolC, sipB, sitC, pagC, msgA, spiA, sopB, sifA, lpfA, csgA, hilA, orgA, iroN, avrA, and sivH (n = 19/24), which are identified as responsible for the pathogenesis of the bacteria during salmonellosis [48]. This evidence concerns the gene SPI1 and salmonellosis.
