Pathogenic Mechanisms Salmonella growth, survival, and virulence respond to a series of stress factors such as pH, oxygen availability, and osmolarity (Altier, 2005; Humphrey, 2004; Ricke, 2003a; Spector and Kenyon, 2012). When there is a lack of nutrients, such as carbon sources, this can trigger global stress responses in Salmonella resulting in a changed physiological state with a wide array of genes impacted including some virulence genes (Spector and Kenyon, 2012).

2007). Some strains of STEC are acid-resistant and non-pathogenic E. coli Antimicrobial Resistance of Shiga Toxin-Producing Escherichia coli Chapter | 2 27 strains are, in general less acid-tolerant than pathogenic strains (Gorden and Small, 1993). Acid-resistant strains of E. , 2007). Both organic acid and inorganic acid inhibit the growth of bacterial pathogens, but the mechanism of inhibition by the two acids is completely different. At pH below their pKa values organic acids are present in the un-disassociated form which can diffuse across bacterial cell membrane, subsequently dissociate and acidify cytoplasm causing the ease of bacterial metabolism and death of bacterial cells.
