Summary: This study characterized 17 L. monocytogenes strains from fish and fish-processing environments in Poland in terms of relatedness, virulence profiles, and resistance genes. The most frequent serogroups were IIa and IIb; sequence types (ST) were ST6 and ST121; and clonal complexes (CC) were CC6 and CC121. Despite differential genotypic subtypes, most strains had similar antimicrobial resistance profiles; however, some genes were located on mobile genetic elements that could be transferred to other bacteria.

Summary: In this study, the diversity of virulence factors associated with the mechanisms of pathogenicity, persistence, and formation of biofilm in L. monocytogenes were investigated using whole-genome sequencing. The findings contribute to the understanding of the genomic diversity and epidemiology of L. monocytogenes, and provide valuable insights for establishing control measures to reduce its impact on the environment and consumers.

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: This study describes a group of GNAT-Xre TA modules widely distributed among Pseudomonas species, with one member - PacT toxin positively regulating iron acquisition in Pseudomonas aeruginosa. Additionally, PacT can directly bind to Fur and attenuate its DNA-binding affinity to permit expression of downstream iron-acquisition-related genes.

Summary: Listeria monocytogenes, a bacterium posing challenges to public health and food safety, exhibits variations in virulence and stress resilience among different strains. Strains with different serotypes and genotypes have distinct pathogenicity and survival abilities, which contribute to food product contamination and outbreaks of listeriosis. Genetic and phenotypic differences between strains may play a crucial role in determining virulence and stress sensitivity.

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: Listeria monocytogenes is an important food-borne pathogen that can contaminate food. Traditional methods to inhibit its growth and extend food shelf life often damage food quality. Probiotics, as a biological antimicrobial method, have shown promise in effectively inhibiting the growth of L. monocytogenes. This review summarizes human listeriosis, current contamination situations, and discusses the effects and mechanisms of probiotics in inhibiting L. monocytogenes in foods. The latest applications of probiotics in dairy, meat, and fresh products are also presented and discussed.

Summary: This study evaluated the biofilm eradication ability of a specific bacteriophage against Listeria monocytogenes biofilms and investigated the gene and structural changes after phage treatment. The results showed that the phage was able to effectively eliminate the biofilms and caused up-regulation of certain genes and changes in structural parameters.

Summary: The Pediococcus acidilactici strains isolated from Brazilian artisanal cheese showed high bacteriocin activity against Listeria monocytogenes and Enterococcus spp. The bacteriocins produced by these strains exhibited bactericidal mode of action against certain strains and displayed safety-related genes, although the presence of possible virulence factors and antibiotic resistance should be further investigated.
