Food Safety Publications

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.

  1. Improvement of antimicrobial susceptibility testing in biofilm-growingcoagulase-negative Staphylococcus hominis

    • Fri, 05/27/2022 - 04:00
    • Journal of Microbiological Methods
    • Coagulase-negative Staphylococcus hominis causes bloodstream infections and often can form biofilms on medical devices. This study aimed to improve the current methodology for antimicrobial susceptibility testing (AST) in biofilm-growing S. hominis isolates. Biofilm production of S.

  2. Spectinomycin, gentamicin, and routine disc diffusion testing: An alternative for the treatment and monitoring of multidrug-resistant Neisseria gonorrhoeae?

    • Sat, 05/07/2022 - 04:00
    • Journal of Microbiological Methods
    • Introduction

      Neisseria gonorrhoeae is a major concern of public health due to its extraordinary capacity to develop and acquire resistance to different antimicrobials used to treat gonorrhoea. Limited treatment options and uncontrolled transmission have raised the need to assess the antimicrobial susceptibility profile of the isolates and to establish affordable alternatives for laboratory diagnosis.

  3. Comparison of peaks in the matrix-assisted laser desorption ionization time-of-flight mass spectrometry spectra of Staphylococcus aureus grown on various blood agar plates

    • Fri, 04/22/2022 - 04:00
    • Journal of Microbiological Methods
    • Matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS) is routinely used for bacterial identification in clinical laboratories. Bacterial protein expression may differ according to their growth conditions, especially the culture medium composition.

  4. Role of temperature, nutrition, oxygen, osmolality, and bacterial strain in inducing a viable but non-culturable state in Campylobacter jejuni

    • Wed, 03/30/2022 - 04:00
    • Journal of Microbiological Methods
    • Campylobacter jejuni is a globally important foodborne pathogen that can exist environmentally in a viable but non-culturable (VBNC) state, leading to missed detection of VBNC cells in food and false results in epidemiological surveillance. To establish a method for its resuscitation from the VBNC state and enable better detection, the mechanisms by which C. jejuni are induced into the VBNC state should be understood in detail.

  5. A study of various factors affecting satellitism tests of Haemophilus influenzae and Haemophilus parainfluenzae using Staphylococcus aureus as the source of NAD

    • Sat, 01/15/2022 - 12:00
    • Journal of Microbiological Methods
    • Many factors affecting satellitism tests are unclear, and it is difficult to avoid misidentification, even if the medium is properly selected. We investigated the factors causing false-positive results for Haemophilus influenzae and false-negative results for Haemophilus parainfluenzae in the satellitism tests using Staphylococcus aureus as the source of nicotinamide adenine dinucleotide (NAD). H.

      Botulinum neurotoxin types C, D and their mosaic forms C/D and D/C produced mainly by Clostridium botulinum types C and D cause botulism in animals and belong to the most toxic substances for poultry and fish. In addition to intoxications, also toxoinfections with C. botulinum types C and D play a role that should not be underestimated, especially in veterinary medicine.

    • Journal of Microbiological Methods
    • Author(s): Kento Koyama, Kyosuke Kubo, Satoko Hiura, Shige Koseki To predict bacterial population behavior in food, statistical models with specific function form have been applied in the field of predictive microbiology. Modelers need to consider the linear or non-linear relationship between the response and explanatory variables in the statistical modeling approach. In the present study, we focused on machine learning methods to skip definition of primary and secondary structure model.
