  1. Innovative Combined Technology with Encapsulated EVOO and Infrared Processing Against Salmonella and Listeria monocytogenes in Breaded Poultry Products

    • Food and Bioprocess Technology
    • The high Salmonella and Listeria monocytogenes risk in poultry products reinforces the urgent need for new technologies with high antimicrobial effects. In that sense, a combined technology consisting of encapsulated extra virgin olive oil (EVOO) during chicken nugget breading combined with infrared processing was hereby studied at three levels (experiments). The high in vitro EVOO antimicrobial activity (up to 74%), which was 1.2-fold higher against L.

  4. Inactivation of Salmonella Enteritidis on hatchery and table eggs using a gas phase-hydroxyl radical process

    • Journal of Food Protection
    • Eggs represent a significant vehicle for Salmonella Enteritidis with the pathogen being transferred to chicks in the hatchery, or to consumers via table eggs. In the following, the efficacy of a gas phase hydroxyl-radical process for decontaminating hatchery and table eggs was evaluated.

  9. Analysis of random mutations in Salmonella Gallinarum dihydropteroate synthase conferring sulfonamide resistance

    • Archives of Microbiology
    • In bacteria and primitive eukaryotes, sulfonamide antibiotics block the folate pathway by inhibiting dihydropteroate synthase (FolP) that combines para-aminobenzoic acid (pABA) and dihydropterin pyrophosphate (DHPP) to form dihydropteroic acid (DHP), a precursor for tetrahydrofolate synthesis. However, the emergence of resistant strains has severely compromised the use of pABA mimetics as sulfonamide drugs.

  20. Frequency of isolation and phenotypic antimicrobial resistance of fecal Salmonella enterica recovered from dairy cattle in Canada

    • Journal of Dairy Science
    • Salmonellosis is one of the leading causes of gastrointestinal infections in humans. In Canada, it is estimated that approximately 87,500 cases of salmonellosis occur every year in humans, resulting in 17 deaths. In the United States, it is estimated that 26,500 hospitalizations and 420 deaths occur every year. In dairy cattle, infections caused by nontyphoidal Salmonella enterica can cause mild to severe disease, including enteritis, pneumonia, and septicemia.

  25. A comprehensive review of the applications of bacteriophage-derived endolysins for foodborne bacterial pathogens and food safety: recent advances, challenges, and future perspective

    • Frontiers in Microbiology
    • Foodborne diseases are caused by food contaminated by pathogenic bacteria such as Escherichia coli, Salmonella, Staphylococcus aureus, Listeria monocytogenes, Campylobacter, and Clostridium, a critical threat to human health. As a novel antibacterial agent against foodborne pathogens, endolysins are peptidoglycan hydrolases encoded by bacteriophages that lyse bacterial cells by targeting their cell wall, notably in Gram-positive bacteria due to their naturally exposed peptidoglycan layer.
