  3. Biological Properties of Bee Bread Collected from Apiaries Located across Greece

    • Antibiotics

    • Bee bread is the only fermented product of the beehive. It constitutes the main source of proteins, lipids, vitamins, and macro- and microelements in honeybee nutrition and it exerts antioxidant and antimicrobial properties, though research on these aspects has been limited so far. In this study 18 samples of Greek bee bread, two of which were monofloral, were collected during different seasons from diverse locations such as Crete and Mount Athos and were tested for their bioactivity.

    • Comprehensive Reviews in Food Science and Food Safety, EarlyView. Nontyphoidal salmonellae are among the most prevalent foodborne pathogens causing gastrointestinal infections worldwide. A high number of cases and outbreaks of salmonellosis are associated with the consumption of eggs and egg products, and several of these occur at the household level.

  7. Analysis of Microbiological and Chemical Hazards in Edible Insects Available to Canadian Consumers

    • Journal of Food Protection

    • Edible insects are a novel food in most countries; their popularity is growing because of their high protein/low fat content, ease of cultivation, and small environmental impact. To our knowledge, this is the first report that addresses both microbiological and chemical hazards in edible insects. Samples were collected from retail stores or purchase through e-commerce. A total of 51 samples of dried whole insects or insect powders were tested for generic Escherichia coli ( E.

  12. “One for All”: Functional Transfer of OMV-Mediated Polymyxin B Resistance From Salmonella enterica sv. Typhi ΔtolR and ΔdegS to Susceptible Bacteria

    • Frontiers in Microbiology

    • The appearance of multi-resistant strains has contributed to reintroducing polymyxin as the last-line therapy. Although polymyxin resistance is based on bacterial envelope changes, other resistance mechanisms are being reported. Outer membrane vesicles (OMVs) are nanosized proteoliposomes secreted from the outer membrane of Gram-negative bacteria.

    • Journal of Bacteriology

    • Proteolysis is a fundamental property of all living cells. In the bacterium Salmonella enterica serovar Typhimurium (S. Typhimurium), the HspQ protein controls the specificities of the Lon and ClpAP proteases. Upon acetylation, HspQ stops being a Lon substrate and no longer enhances proteolysis of the Lon substrate Hha.

    • Journal of Food Safety, EarlyView. This paper aims to create a new hybrid ensemble data mining model to predict the Salmonella presence in agricultural surface waters based on the combination of heterogeneous ensemble approach for feature selection, clustering, regression, and classification algorithms. The data set for this study was collected from six agricultural ponds in Central Florida consisting of 23 features with 540 instances (26 Salmonella positive and 514 Salmonella negative).

  17. Inhibitory Activity of Natural Synergetic Antimicrobial Consortia Against Salmonella enterica on Broiler Chicken Carcasses

    • Frontiers in Microbiology

    • The currently most utilized antimicrobial agent in poultry processing facilities is peracetic acid, a chemical increasingly recognized as hazardous to human health. We evaluated the efficacy of mixtures of natural antimicrobial compounds, namely reuterin, microcin J25, and lactic acid, for reducing the viability of Salmonella enterica and total aerobes on broiler chicken carcasses. The compounds were compared singly and in combination with water and 0.1% peracetic acid.

    • ABSTRACT Cobamides are cobalt-containing cyclic tetrapyrroles used by cells from all domains of life but only produced de novo by some bacteria and archaea. The "late steps" of the adenosylcobamide biosynthetic pathway are responsible for the assembly of the nucleotide loop and are required during de novo synthesis and precursor salvaging.
