Summary: The study evaluated the combined effects of temperature and pH on the expression of biofilm, stress, and virulence genes in Salmonella Enteritidis and Salmonella Typhimurium. The findings indicated that temperature and pH did not have a significant effect on the gene expression levels in these Salmonella strains.

Summary: The study identified lytic Salmonella phages isolated from livestock farms in Ohio, USA, which showed activities against various Salmonella serovars, including Typhimurium and Enteritidis. The phages were found to be viable in acidic and alkaline environments as well as at temperatures ranging from 4 to 55 degrees Celsius. Combination of phage treatment and mild heat resulted in significant reductions in Salmonella Typhimurium and Salmonella Enteritidis levels in liquid whole eggs.

Summary: In this study, a rapid and accurate on-site serotyping method for Salmonella enterica subsp. enterica serovar Enteritidis, Thompson, and Typhimurium was developed. This method, based on specific marker genes, utilizes portable equipment and a simple DNA extraction step. The method shows high specificity for the three serovars and can be completed within 25 minutes, making it ideal for field detection.

Summary: Xylo-oligosaccharide (XOS) protects against Salmonella infection by modulating gut microbiota, enhancing the intestinal barrier, and inhibiting intestinal inflammation. It stimulates Bifidobacterium to resist Salmonella colonization and reduces inflammatory reactions.

Summary: A QMRA model was developed to evaluate the effectiveness of border control for Salmonella in frozen poultry products. The model consists of three modules and the current border control based on one sample per batch only achieves a 27% risk reduction.

Summary: This study successfully developed a multiplex qPCR molecular diagnostic kit for rapid and accurate diagnosis of Salmonella enterica serovar Enteritidis and S. enterica serovar Typhimurium in poultry samples, demonstrating 100% specificity and sensitivity values. The newly developed technique can serve as an alternative method to conventional serotyping in laboratories lacking adequate infrastructure.

Summary: The study found that supplementing laying hens' diets with 2mg/kg of vitamin K (VK) can enhance bone strength under Salmonella Enteritidis challenge. The medullary area has been proven to be a sensitive biomarker for bone calcium loss caused by SE infection. There is an interaction between SE challenge and VK levels regarding tibia strength and serum Ca levels.

Summary: This study analyzed a collection of Salmonella enterica strains collected in Italy over a 3-year period. The prevalence of colistin-resistant strains was determined, and mobile colistin resistance (mcr) genes were detected. Additionally, chromosomal mutations potentially involved in colistin resistance were identified. The study highlights the importance of national surveillance in monitoring colistin resistance and studying new mechanisms.

Summary: This study aimed to evaluate the ability of different strains of Lactobacillus spp. to improve the integrity of the intestinal barrier, exert anti-inflammatory and immunomodulatory activity, and prevent Salmonella Typhimurium and enteroinvasive Escherichia coli (EIEC) infections. The results showed that L. brevis, L. reuteri, and L. rhamnosus were the most effective in protecting the intestinal epithelium.
