Summary: In this study, a Salmonella temperate phage vB_Sal_PHB48 was isolated from sewage and characterized. It was found that the integration of PHB48 could significantly enhance the virulence and biofilm formation ability of Salmonella, as well as improve its colonization and contamination ability in food samples. These findings highlight the increased harm to food matrices and public health security by highly pathogenic Salmonella induced by temperate phages.

Summary: Salmonella Typhimurium inactivation in in-shell eggs was studied using radio frequency processes combined with hot air, hot water immersion, and hot water spray. The inactivation of Salmonella did not follow first-order kinetics. Statistical analysis indicated that the Weibull distribution and extreme tailing model were the best models to describe the microbial inactivation during radio frequency treatments.

Summary: This study investigated the epidemiological characteristics of Salmonella enterica subsp. enterica serovar Typhimurium in China, focusing on multi-locus sequence typing, biofilm-forming ability, antimicrobial susceptibility testing, and resistant genes. Results showed that ST34 was the dominant type, accounting for 82.4%, followed by ST19 at 15.9%. ST34 exhibited higher resistance levels compared to ST19. Importantly, the emergence of high-level antibiotic resistance S. typhimurium ST34 with strong biofilm-forming ability raises concerns for public health safety.

Summary: This study evaluated the effect of glucose concentration on the biofilm formation of Salmonella typhimurium. The results showed that low-sugar conditions were more conducive to biofilm formation, except for strain ST19. As glucose concentration increased, biofilm formation increased. Other strains stopped forming biofilms at a glucose concentration of 1.5%, but ST19 still had strong biofilm formation ability. ST19 adapted to a high-glucose environment by regulating glucose transport and metabolism, and regulated biofilm formation through upregulation of genes in the two-component system.

Summary: Poultry, especially chicken meat, is thriving globally but also poses threats to human hygiene through the transmission of infectious diseases caused by major foodborne pathogens. To tackle this issue, innovative strategies such as natural compounds, bacteriophages, nanoparticles, coatings, enzymes, and probiotics are emerging to improve food safety and quality, and extend shelf-life. These strategies show potential antimicrobial activities and can enhance the immune system and poultry health. Lactoferrin, bacteriocin, antimicrobial peptides, cell-free supernatants, and biosurfactants are of considerable interest for their prospective application as natural antimicrobials in the poultry processing industry.

Summary: This study investigated the antimicrobial and antibiofilm efficacy of Lactobacillus curvatus B67-produced postbiotic and quercetin against Listeria monocytogenes and Salmonella enterica ser. Typhimurium. The postbiotic showed strong antimicrobial effects mainly due to organic acids, effectively reducing pathogenic biofilm cells on processed meat surfaces. The combination of postbiotic and quercetin increased the leakage of intracellular metabolites and inhibited biofilm formation. This study suggests that postbiotic and quercetin can be used as alternative bio-protective agents in the meat processing industry.

Summary: This study evaluated the potential role of three plant growth-promoting rhizobacteria (PGPR) - Bacillus subtilis, Bacillus amyloliquefaciens, and Pseudomonas monteilii - as biofertilizers. The results showed that the application of PGPR significantly increased the populations of Bacillus and Pseudomonas and promoted the growth of nitrogen-fixing bacteria. The sensory evaluation did not show significant differences, but TSS and color evaluation suggested that PGPR acted as a ripening enhancer.

Summary: This study investigates and compares the genetic characteristics between stress-resistant and -sensitive L. monocytogenes using whole genome sequencing (WGS). The functionality of unique genes in stress-resistant L. monocytogenes, such as carbohydrate and nucleotide transport and metabolism, is distinct from the stress-sensitive group. The virulence gene lisR is more prevalent in stress-resistant L. monocytogenes, and five strains possess the tet(M) antibiotic resistance gene.

Summary: In recent years, there has been an increase in the occurrence of fowl adenovirus 2 (FAdV-2) in China, posing a significant threat to the poultry industry. This study investigated the epidemiology, phylogenetic relationship, genomic characteristics, and pathogenicity of FAdV-2. The results showed that FAdV-2 was the most commonly detected serotype among various FAdV serotypes. Genetic analysis revealed that these FAdV-2 strains formed a distinct branch within the FAdV-D group and had a high nucleotide similarity with reference strains. Recombination analysis identified recombination events between FAdV-2 and FAdV-11 in some strains. Pathogenicity experiments demonstrated that a recombinant FAdV-2 strain caused a high mortality rate and more severe disease in chickens. These findings contribute to our understanding of FAdV-2 and provide a basis for vaccine development.

The results showed that perceived severity and perceived benefits positively influenced vendors' self-efficacy in the wholesale market, while perceived barriers negatively affected self-efficacy in both the wholesale and retail markets. Moreover, cues to action mediated the relationship between perceived severity, perceived benefits, and self-efficacy, and also mediated the effect of perceived susceptibility among wholesale market vendors.
