Summary: The study revealed that biofilm formation and gallidermin resistance of L. monocytogenes are influenced by the mprF gene, with its inactivation leading to enhanced biofilm formation and abiotic surface attachment but compromising invasiveness.

Summary: This study revealed the crucial roles of VirAB and VirS in biofilm formation of L. monocytogenes EGD-e, showing that they are essential for biofilm formation and can function together. While involved in attachment, both VirAB and VirS are not associated with swarming motility. Downregulation of genes flaA, motA, and motB in mutant strains might be the reason for reduced attachment and biofilm formation.

Summary: The study used Tn mutagenesis to identify genes and pathways affecting the growth and fitness of Listeria monocytogenes in minimal medium. The findings revealed that biosynthesis of purines, pyrimidines, ATP, and branched-chain fatty acids plays an important role in the pathogenesis of L. monocytogenes.

Summary: This study aimed to determine the effects of different temperature, NaCl concentration, and pH levels on the adhesion and biofilm formation of Listeria monocytogenes, and to build probability models. The results showed that high temperature promoted adhesion and biofilm formation, while excessive NaCl concentration inhibited both processes. The accuracy of the probability models in predicting the adhesion and biofilm formation boundaries of L. monocytogenes ST9 was reasonably high.

Summary: We investigated the antimicrobial activity of sertraline against Listeria monocytogenes, and its effects on biofilm formation and virulence gene expression. Sertraline showed inhibitory effects on L. monocytogenes at concentrations between 16-32 μg/mL and a bactericidal effect at 64 μg/mL. Sertraline damaged the cell membrane, decreased ATP and intracellular pH, and reduced biofilm formation efficiency. Importantly, low concentrations of sertraline down-regulated the expression of various virulence genes in L. monocytogenes.

Summary: Research showed that different surface topographies and coating compositions significantly impacted the resistance against L. monocytogenes biofilm formation. Coating the native stainless steel surface with Ni-P-PTFE significantly reduced L. monocytogenes contamination. Various coatings on different surfaces were effective in reducing L. monocytogenes contamination, with Dursan showing the best performance on the native surface.

Summary: The aim of this study was to investigate the ability of natural plant-derived products (flavonoid compounds) to inhibit the growth and biofilm-forming ability of Listeria monocytogenes. Among 500 flavonoid compounds, five were identified as promising antibiofilm and antimicrobial agents against Listeria monocytogenes.

Summary: The study showed that the cell-free supernatant of Saccharomyces cerevisiae can inhibit and eradicate the biofilm of Listeria monocytogenes by reducing auto-aggregation, cell surface hydrophobicity, EPS production, as well as downregulating virulence factors and biofilm-related genes. These anti-biofilm effects were confirmed through microscopy techniques, demonstrating the potential of S. cerevisiae to be used as a biocontrol agent in the food industry.

Summary: This study investigated the spatial and temporal differences during the formation of L. monocytogenes biofilms, as well as the transfer and residual of biofilm cells at different stages. The results showed that the transfer rates of biofilm cells had no significant difference between single and ten successive contacts at specific stages, and the transfer rates were correlated with the hydrophobicity of biofilm cells.

Summary: An aptamer-based SERS method was developed for the specific detection of S. enterica at a serovar level. The method can differentiate between different serovars of S. enterica and detect the presence of S. Enteritidis in vitro. The efficacy of the method in detecting S. Enteritidis contaminated ground beef was also demonstrated.
