Research Publications (Food Safety)

This page tracks research articles published in national and international peer-reviewed journals. Recent articles are available ahead of print and searchable by Journal, Article Title, and Category. 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 (requires login) and FDA Grant Funding Agencies (requires login) are also tracked in Scopus.

  2. Antifungal effect of gamma irradiation and sodium dichloroisocyanurate against Penicillium expansum on pears

    • Letters in Applied Microbiology

    • Gamma irradiation (GI) was evaluated for its in vitro and in vivo antifungal activity against Penicillium expansum on pear fruits. GI showed a complete inhibition of spore germination, germ tube elongation, and mycelial of P. expansum, especially 1.8 kGy. GI affected the membrane integrity and cellular leakage of conidia in a dose-dependent manner. Furthermore, the leakage of protein and sugar from mycelia increased along with the dose.

  3. PrfA regulation offsets the cost of Listeria virulence outside the host

    • Environmental Microbiology

    • Virulence traits are essential for pathogen fitness but whether they affect microbial performance in the environment, where they are not needed, remains experimentally unconfirmed. We investigated this question with the facultative pathogen Listeria monocytogenes and its PrfA virulence regulon. PrfA-regulated genes are activated intracellularly (PrfA “ON”) but shut down outside the host (PrfA “OFF”).

  4. Molecular analysis of a conserved signaling system [Microbiology]

    • Proceedings of the National Academy of Sciences

    • We have functionally and structurally defined an essential protein phosphorelay that regulates expression of genes required for growth, division, and intracellular survival of the global zoonotic pathogen Brucella abortus. Our study delineates phosphoryl transfer through this molecular pathway, which initiates from the sensor kinase CckA and proceeds through the ChpT...

  5. An overview on the origin and production of Tetrodotoxin, a potent neurotoxin

    • Journal of Applied Microbiology

    • Tetrodotoxin is a deadly neurotoxin which selectively inhibits Na+ activation mechanism of nerve impulse, without affecting the permeability of K+ ions. Because of this sodium channel blocking action, it is majorly being studied for biomedical applications. Tetrodotoxin is present in taxonomically diverse groups of animals inhabiting terrestrial, marine, fresh water and brackish water environments, still its origin remains unclear.

  6. Thermal inactivation kinetics of hepatitis A virus in homogenized clam meat (Mercenaria mercenaria)

    • Journal of Applied Microbiology

    • Aims
      Epidemiological evidence suggests that hepatitis A virus (HAV) is the most common pathogen transmitted by bivalve mollusks such as clams, cockles, mussels, and oysters. This study aimed to generate thermal inactivation kinetics for HAV as a first step to design adequate thermal processes to control clam-associated HAV outbreaks.

  7. Genotypic and phenotypic diversity of Alicyclobacillus acidocaldarius isolates

    • Letters in Applied Microbiology

    • The fruit juice industry recognizes Alicyclobacillus as a major quality control target microorganism. In this study, we analysed 19 bacterial isolates to identify Alicyclobacillus species by polymerase chain reaction (PCR) and sequencing analyses. Phenotypic and genomic diversity among isolates were investigated by API 50CHB system and ERIC-PCR (enterobacterial repetitive intergenic consensus-PCR), respectively.

  9. Global Distribution and Prevalence of Arcobacter in Food and Water

    • Zoonoses and Public Health

    • The emerging foodborne and waterborne pathogen, Arcobacter, has been linked to various gastrointestinal diseases. Currently, 19 species are established or proposed; consequently, there has been an increase in the number of publications regarding Arcobacter since it was first introduced in 1991.

  10. Methicillin-Resistant Staphylococcus aureus from Brazilian Dairy Farms and Identification of Novel Sequence Types

    • Zoonoses and Public Health

    • The aim of this study was to investigate the phenotypic and genotypic diversity and anti-microbial resistance among staphylococci of dairy herds that originated from Paraiba State, north-eastern Brazil, a region where such studies are rare. Milk samples (n = 552) were collected from 15 dairy farms. Isolates were evaluated for anti-microbial susceptibility by Kirby–Bauer disc diffusion method.

  12. GlnR-mediated regulation of ectABCD transcription expands the role of the GlnR regulon to osmotic stress management

    • Journal of Bacteriology

    • Ectoine and hydroxyectoine are excellent compatible solutes for bacteria to deal with environmental osmotic stress and temperature damages. The biosynthesis cluster of ectoine and hydroxyectoine is widespread among microorganisms and its expression is activated by high salinity and temperature changes.

  13. Structural features reminiscent of ATP-driven protein translocases are essential for the function of a type III secretion associated ATPase

    • Journal of Bacteriology

    • Many bacterial pathogens and symbionts utilize type III secretion systems to interact with their hosts. These machines have evolved to deliver bacterial effector proteins into eukaryotic target cells to modulate a variety of cellular functions. One of the most conserved components of these systems is an ATPase, which plays an essential role in the recognition and unfolding of proteins destined for secretion by the type III pathway.
