Summary: The study aimed to characterize phage resistance mechanisms and genomic differences in S. Typhimurium DT104 and DT104b that may explain divergent phage reaction patterns, but found no unique genetic determinants. Experimental assessment of phage-specific receptors on the bacterial cell surface and analysis of bacterial transcriptome using RNA sequencing were suggested to further understand bacterial susceptibility to phages. The use of Anderson phage typing scheme of Salmonella Typhimurium can help improve the understanding of host-phage interactions and lead to the development of phage-based technologies for infection control.

Summary: This study explores the resistance mechanism and activity of the antimicrobial peptide MccY against Salmonella strains. The deletion of Ton system genes resulted in resistance to MccY and mutants showed increased susceptibility to MccY under a low-iron condition. MccY may decrease the virulence of S. Typhimurium by altering multiple physiological properties.

Summary: Salmonella alters cellular processes to improve intracellular fitness during host infection by rewiring cellular transcriptional regulation through alternative sigma factors such as rpoS. Deprivation of outer membrane protein YcfR in Salmonella Typhimurium leads to decreased intracellular survival and downregulation of SPI-2 genes, which is abolished in the absence of rpoS. RpoS-associated stress responses in Salmonella due to impaired envelope integrity may reciprocally downregulate the expression of SPI-2 genes to reduce its virulence.

Summary: The study investigated the influence of cuminaldehyde (CUM) on cell membrane and genomic DNA of Salmonella enterica serovar Typhimurium (S. Typhimurium), and revealed its antibacterial mechanism. CUM could bind to bacterial membrane proteins and change its structure and conformation, leading to the leakage of intracellular substances and the destruction of cell integrity. DNA interaction analysis showed that CUM bound to genomic DNA through groove mode, affecting the normal functioning of S. Typhimurium.

Summary: In this study, it was found that Apis laboriosa honey (ALH) harvested in China has antibacterial activity against Salmonella enterica serovar Typhimurium (S. Typhimurium). The physicochemical parameters and antioxidant activity of ALH were influenced by the time and region of harvest. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of ALH against S. Typhimurium were similar to UMF5+ manuka honey. Proteomic experiment revealed the antibacterial mechanism of ALH.

Summary: Mild heat treatment can enhance the thermal resistance of S. Typhimurium and reduce membrane damage and heat-induced injury, leading to increased tolerance against heat, alcohol, and salt stress. Further research into the heat shock response mechanism of S. Typhimurium may provide insights for developing microbial control measures in food processing.

Summary: The study evaluated the use of microwave-assisted induction heating (MAIH) system for cooking white shrimp, finding that longer heating times at specific temperatures could fully cook and sterilize the shrimp samples without contamination. It was recommended to heat white shrimp at 130 degrees C for 80 s or at 90 degrees C for 100 s for best results in appearance, microbial safety, and cook loss. This novel MAIH technology allows for post-packaging heating and sterilization of food products, eliminating post-pollution issues.

Summary: This study investigated the inactivation mechanisms of Listeria monocytogenes under high-pressure processing (HPP) through label-free quantitative proteomic analysis. The results revealed that HPP can promote translation initiation but impairs protein synthesis due to a shortage of proteins responsible for elongation, termination, and recycling. These findings provide theoretical support for using HPP to combat Listeriosis illness and improve the safety of ready-to-eat foods.

Summary: Commercial cheese brines can be a reservoir for salt-tolerant pathogens. This study found that the addition of hydrogen peroxide can effectively reduce the population of L. monocytogenes in cheese brines, especially at higher temperatures and salt concentrations. The presence of indigenous microorganisms may neutralize the effect of hydrogen peroxide.
