Summary: The study demonstrated the effectiveness of blue light (BL) in inactivating Salmonella Enteritidis on eggshells, while maintaining eggshell freshness. BL-treated eggs showed lower weight loss, higher Haugh unit, and higher total amino acid content during storage period, indicating the advantage of BL treatment in maintaining egg quality.

Summary: This study developed a hierarchical machine learning model to rapidly identify and trace the geographical source of Salmonella enterica serovar Enteritidis infections from whole genome sequencing data. The model achieved high accuracy in predicting the continent, sub-region, and country of origin, and provides results within 4 minutes per sample, facilitating rapid outbreak resolution and real-time genomic epidemiology.

Summary: In recent years, there has been a more cautious use of drugs on livestock farms, leading to the consideration of alternative products in order to reduce the risk of antibiotic resistance. This study aimed to evaluate the effectiveness of garlic in inhibiting Salmonella enterica subsp. enterica serovar Enteritidis and to determine its Minimal Inhibitory Concentration (MIC)(90) and MIC50 values. The results showed that garlic has the potential to inhibit the growth of S. Enteritidis in vitro, with efficacy varying depending on the microbial concentration used.

Summary: This study investigated the protective effects and potential mechanisms of cranberry pomace against Salmonella Enteritidis-induced chicken hepatic cell damage. The results showed that cranberry pomace increased the viability of Salmonella-infected chicken hepatoma cells and reduced Salmonella adhesion and invasion. Additionally, it downregulated the expression of key genes involved in Salmonella entry and increased the expression of antioxidant genes. These findings provide opportunities to develop sustainable, safe, and economic strategies to reduce Salmonella colonization and pathogenesis.

Summary: The study investigated the prevalence and antimicrobial resistance of Salmonella enterica serovar Enteritidis in broiler chickens in Shandong Province, China. It found that S. Enteritidis was the predominant serovar with high antimicrobial resistance rates to several antibiotics. Multidrug resistance, particularly to fluoroquinolone, showed an increasing trend from 2013 to 2018. This study provides updated information on antimicrobial resistance data and risk assessment for Salmonella Enteritidis in broiler chickens in Shandong Province, which can be valuable for future surveillance activities to ensure chicken supply safety.

Summary: Salmonella enterica serovar Enteritidis is a common pathogen that can cause significant public health problems and economic losses. This study investigated the genetic resistance of poultry to Salmonella infection and found that inflammatory genes were activated in chickens infected with Salmonella Enteritidis. The findings provide important insights into the molecular mechanisms and epigenetic regulation in chicken response to Salmonella infection.

Summary: This study investigated the response of the cecal microbiota to an inflammatory state caused by Salmonella enterica serovar Enteritidis infection. It was found that the infection improved microbial diversity and promoted microbiota evolution. Some intestinal microorganisms were found to thrive in an inflamed environment, while the overall function of the cecal microbiome was to maintain homeostasis through the up-regulation of microbial metabolism pathways. The infection of S. Enteritidis was closely related to multiple inflammation-related genes and S. Enteritidis was able to compete with symbiotic bacteria.

Summary: The contribution of food vehicles to the pathogenicity of disease-causing microorganisms, specifically Salmonella enterica serovar Enteritidis, has been revealed in a study. The research shows that the growth of Salmonella Enteritidis in egg yolk enhances its virulence compared to growth in tryptic soy broth. This finding is supported by transcriptional analysis results, which indicate the upregulation of virulence-related genes in Salmonella Enteritidis grown in egg yolk. These findings highlight the significance of egg yolk as a medium for the risk assessment of salmonellosis.

Summary: The study found that ethanol adaptation in Salmonella Enteritidis is stable under cold conditions and in meat juices, but less stable at room temperature. This suggests that the impact of cold conditions and meat juices on ethanol adaptation should be considered during comprehensive risk analysis in food processing.

Summary: This study investigated the pathogenicity, antimicrobial resistance, and multilocus sequence types of Salmonella enterica subspecies enterica serovar Enteritidis in the central region of peninsular Malaysia. The isolates showed multidrug-resistance features and had various virulence genes. The findings suggest potential risks to humans and livestock from this foodborne pathogen.

Summary: This study investigated the efficacy of a killed Salmonella Chitosan nanoparticle (CNP) vaccine on broilers. The results showed that the CNP vaccine significantly enhanced the immune response to Salmonella antigens in poultry, and reduced gut permeability and Salmonella count after infection. The study suggests that the CNP vaccine is a viable alternative to conventional Salmonella poultry vaccines.

Summary: Research shows that two RyhB paralogs of Salmonella enterica serovar Enteritidis can upregulate Type III secretion system (T3SS) effectors, affecting the bacteria's invasion into intestinal epithelial cells, and thereby impacting its virulence.
