Abstract: Similar to other bacteria, certain serovars of Salmonella sp. have developed effective defensive strategies to counter oxidative stress induced by reactive oxygen species, especially when exposed to sublethal doses. Beyond oxidative stress, microorganisms encounter additional stressors such as acid and thermal stress, osmotic changes, and water scarcity. These challenges are often explored by the industry as alternative methods to microbial destruction. Understanding and studying the mechanisms behind this process are necessary not only to determine the activation of new genes involved in the adaptive stress response but also to identify virulence factors present during bacterial infection in the host. Thus, this information is essential for the development of new antimicrobial products, as well as for a better understanding of the virulence and pathogenesis of Salmonella enterica.
