Investigating the Impact of Acid Adaptation on Cross-Protection in Salmonella Typhimurium and Its Regulatory Mechanisms Based on the PmrA/B Two-Component System

This study investigated whether the slightly acidic environment in the meat industry activates the Salmonella PmrA/B two-component regulatory system (TCS), thereby enhancing acid tolerance and cross-protection, by constructing a mutant strain lacking the response regulator PmrA. Results showed that...
