Induction of the Viable-but-Nonculturable State in Salmonella Contaminating Dried Fruit

Jayeola, V., Farber, J. M., & Kathariou, S. (2021, November 3). Applied and Environmental Microbiology.

By: V. Jayeola n, J. Farber* & S. Kathariou n

author keywords: dried fruit; survival; low-moisture foods; Salmonella; confocal microscopy; viable but nonculturable
MeSH headings : Colony Count, Microbial; Food Microbiology; Food, Preserved / microbiology; Fruit / microbiology; Humans; Microbial Viability; Salmonella / physiology; Temperature
topics (OpenAlex): Listeria monocytogenes in Food Safety; Food Safety and Hygiene; Salmonella and Campylobacter epidemiology; Vibrio bacteria research studies; Melamine detection and toxicity
TL;DR: Findings from this study suggest that unique stressors on dried fruit can induce the VBNC state in Salmonella, thus rendering it undetectable with culture-based methods even though the bacteria remain viable. (via Semantic Scholar)

Validation of an ampicillin selection protocol to enrich for mutants of Listeria monocytogenes unable to replicate on fresh produce

Jayeola, V., Parsons, C., Gorski, L., & Kathariou, S. (2019, April 1). FEMS Microbiology Letters.

By: V. Jayeola n, C. Parsons n, L. Gorski * & S. Kathariou n

author keywords: Listeria monocytogenes; growth; mutants; genes; produce; cantaloupe; ampicillin selection
MeSH headings : Ampicillin / pharmacology; Anti-Bacterial Agents / pharmacology; Bacterial Proteins / genetics; Bacterial Proteins / metabolism; Cucumis melo / microbiology; Listeria monocytogenes / drug effects; Listeria monocytogenes / genetics; Listeria monocytogenes / growth & development; Listeria monocytogenes / metabolism; Mutation
topics (OpenAlex): Listeria monocytogenes in Food Safety; Microbial Inactivation Methods; Viral Infectious Diseases and Gene Expression in Insects
TL;DR: Ampicillin selection can facilitate discovery of genes essential for growth of L. monocytogenes on fresh produce by enriching its cold-sensitive mutant L1E4 on cantaloupe rind fragments while growing cells of the wildtype were killed by ampicillin. (via Semantic Scholar)

Capacity of Listeria monocytogenes Strains from the 2011 Cantaloupe Outbreak To Adhere, Survive, and Grow on Cantaloupe

Martinez, M. R., Osborne, J., Jayeola, V. O., Katic, V., & Kathariou, S. (2016, May 1). Journal of Food Protection.

By: M. Martinez n, J. Osborne n, V. Jayeola n, V. Katic* & S. Kathariou  n

author keywords: Adherence; Cantaloupe; Growth; Listeria monocytogenes; Outbreak; Serotype
MeSH headings : Cucumis melo; Disease Outbreaks; Food Microbiology; Listeria monocytogenes; Listeriosis / epidemiology
topics (OpenAlex): Listeria monocytogenes in Food Safety; Microbial Inactivation Methods; Food Safety and Hygiene
TL;DR: All strains from the 2011 cantaloupe outbreak were able to adhere and grow, with ∼10-fold increases after 7 days at 4 or 8°C and after 24 h at 25°C, with a propensity for more growth on rind than on flesh or in extract. (via Semantic Scholar)
