Research Publications (Food Safety)

The Food Safety Publications tracks research that is published across national and international peer-reviewed journals. Recent articles are available ahead of print and searchable by Journal, Article Title, and Category. The research publications are tracked across six categories: Bacterial Pathogens, Chemical Contaminants, Natural Toxins, Parasites, Produce Safety, and Viruses. Articles produced by USDA Grant Funding Agencies and FDA Grant Funding Agencies are also tracked.

  7. Transient Glycolytic Complexation of Arsenate Enhances Resistance in the Enteropathogen Vibrio cholerae

    • Thu, 09/15/2022 - 04:00
    • mBio
    • mBio, Ahead of Print. The ubiquitous presence of toxic arsenate (AsV) in the environment has raised mechanisms of resistance in all living organisms. Generally, bacterial detoxification of AsV relies on its reduction to arsenite (AsIII) by ArsC, followed by the export of AsIII by ArsB. However, how pathogenic species resist this metalloid remains largely unknown.

  8. Prevalence and diversity of type VI secretion systems in a model beneficial symbiosis

    • Wed, 09/14/2022 - 04:00
    • Frontiers in Microbiology
    • The type VI secretion system (T6SS) is widely distributed in diverse bacterial species and habitats where it is required for interbacterial competition and interactions with eukaryotic cells. Previous work described the role of a T6SS in the beneficial symbiont, Vibrio fischeri, during colonization of the light organ of Euprymna scolopes squid. However, the prevalence and diversity of T6SSs found within the distinct symbiotic structures of this model host have not yet been determined.

  10. Ferrous sulfate efficiently kills Vibrio parahaemolyticus and protects salmon sashimi from its contamination

    • Wed, 09/14/2022 - 04:00
    • International Journal of Food Microbiology
    • The primary seafood-borne pathogen Vibrio parahaemolyticus seriously threats the health of consumers preferring raw-fish products, becoming a global concern in food safety. In the present study, we found ferrous sulfate (FeSO4), a nutritional iron supplement, could efficiently induce the death of V. parahaemolyticus. Further, the bactericidal mechanisms of FeSO4 were explored. With a fluorescent probe of Fe2+, a significant influx of Fe2+ was determined in V.

  12. Ruminal background of predisposed milk urea (MU) concentration in Holsteins

    • Tue, 09/13/2022 - 04:00
    • Frontiers in Microbiology
    • Efforts to reduce nitrogen (N) emissions are currently based on the optimization of dietary- N supply at average herd N requirements. The implementation of the considerable individual differences and predispositions in N- use efficiency and N- excretion in breeding programs is hampered by the difficulty of data collection. Cow individual milk urea (MU) concentration has been proposed as an easy-to-measure surrogate trait, but recent studies questioned its predictive power.

  13. Effect of a single amino acid substitution G98D in a ribosome-associated essential GTPase, CgtA, on the growth and morphology of Vibrio cholerae

    • Tue, 09/13/2022 - 04:00
    • Archives of Microbiology
    • CgtA, a highly conserved 50S ribosome-associated essential GTPase, acts as a repressor of the stringent stress response under nutrient-rich growth conditions to suppress basal levels of the alarmone ppGpp in V. cholerae. To further explore the in vivo functionality of CgtA, we introduced an amino acid substitution, i.e., Gly98Asp, in a conserved glycine residue in the N-terminal domain. The constructed V. cholerae mutant was designated CgtA(G98D).

    • Fish & Shellfish Immunology
    • Octopamine and Tyramine are biogenic amines that have been demonstrated to play an important immunological role in white shrimp, Litopenaeus vannamei. G protein-coupled receptors, known as seven-transmembrane domain receptors, are a variety of neurotransmitter receptors which are sensitive to biogenic amines for initiating the cell signaling pathway. In present study, we cloned and characterized an octopamine/tyramine receptor (LvOA/TA-R) from the hemocytes of L.

  20. Microbiome analysis reveals the effects of black soldier fly oil on gut microbiota in pigeon

    • Tue, 09/06/2022 - 04:00
    • Frontiers in Microbiology
    • The gut microbiota plays an important role in poultry physiology, immunity and metabolism. Black soldier fly oil is known to have a positive effect on the gut microbiota. However, the specific effect of black soldier fly oil on the composition and structure of the gut microbiota of the pigeon is unknown. In this experiment, 16S rDNA high-throughput sequencing was carried out to study the effect of different doses of black soldier fly oil on the changes of pigeon intestinal microbes.

    • Frontiers in Cellular and Infection Microbiology
    • Soybean isoflavones (SIs) are widely found in food and herbal medicines. Although the pharmacological activities of SIs have been widely reported, their effects on the intestinal microecology of normal hosts have received little attention. Five-week-old Kunming (KM) mice were administered SIs (10 mg/kg/day) for 15 days. Food intake, body weight, and digestive enzyme activity were measured.

    • Thu, 09/01/2022 - 04:00
    • Fish & Shellfish Immunology
    • Cadmium (Cd2+) and copper (Cu2+) are considered immunotoxic metals and their presence in combination in the aquatic environment may cause effects on shrimp species as Litopenaeus vannamei. Thus, this research evaluates the combined effects of Cd2+ and Cu2+ on shrimp inoculated with Vibrio harveyi bacteria. The experiments were performed at 96-hours of exposure to sublethal concentrations of both metals.
