Addressing the safety of new food sources and production systems

Comprehensive Reviews in Food Science and Food Safety, Volume 23, Issue 3, May 2024.
Abstract New food sources and production systems (NFPS) are garnering much attention, driven by international trade, changing consumer preferences, potential sustainability benefits, and innovations in climate‐resilient food production systems. However, NFPS can introduce new challenges for food safety agencies and food manufacturers.

Insight into Shiga toxin genes encoded by Escherichia coli O157 from whole genome sequencing [PDF]

, 2015
The ability of Shiga toxin-producing Escherichia coli (STEC) to cause severe illness in humans is determined by multiple host factors and bacterial characteristics, including Shiga toxin (Stx) subtype.

Lactic acid bacteria and spoilage bacteria: Their interactions in Escherichia coli O157:H7 biofilms on food contact surfaces and implications for beef contamination

Journal of Food Safety, Volume 44, Issue 1, February 2024.
Regardless of temperature, more viable O157:H7 cells were transferred from moist biofilms on TPU surfaces to beef. At 25°C, biofilm formed by Pseudomonas aeruginosa and Comamonas korensis exhibited the lowest O157:H7 transfer to beef. At 10°C, none of the multispecies biofilms affected the number of O157:H7 transfers to beef.

Mathematical treatment of PDE model describing chemotactic E. coli colonies [PDF]

, 2020
We consider an initial-boundary value problem describing the formation of colony patterns of bacteria Escherichia coli. This model consists of reaction-diffusion equations coupled with the Keller-Segel system from the chemotaxis theory in a bounded domain, supplemented with zero-flux boundary conditions and with non-negative initial data.

Sources and contamination routes of seafood with human pathogenic Vibrio spp.: A Farm‐to‐Fork approach

Comprehensive Reviews in Food Science and Food Safety, Volume 23, Issue 1, January 2024.
Abstract Vibrio spp., known human foodborne pathogens, thrive in freshwater, estuaries, and marine settings, causing vibriosis upon ingestion. The rising global vibriosis cases due to climate change necessitate a deeper understanding of Vibrio epidemiology and human transmission. This review delves into Vibrio contamination in seafood, scrutinizing its

Osmotaxis in Escherichia coli through changes in motor speed [PDF]

, 2017
Bacterial motility, and in particular repulsion or attraction towards specific chemicals, has been a subject of investigation for over 100 years, resulting in detailed understanding of bacterial chemotaxis and the corresponding sensory network in many bacterial species.

Asymmetric split-ring plasmonic nanostructures for optical sensing of Escherichia coli [PDF]

arXiv, 2022
Strategies for in-liquid micro-organism detection are crucial for the clinical and pharmaceutical industries. While Raman spectroscopy is a promising label-free technique for micro-organism detection, it remains challenging due to the weak bacterial Raman signals.

Host response to the subtilase cytotoxin produced by locus of enterocyte effacement‐negative Shiga‐toxigenic Escherichia coli

Microbiology and immunology, 2020
Shiga‐toxigenic Escherichia coli (STEC) is a major bacterium responsible for disease resulting from foodborne infection, including bloody diarrhea and hemolytic uremic syndrome. STEC produces important virulence factors such as Shiga toxin (Stx) 1 and/or

Advancements in Predictive Microbiology: Integrating New Technologies for Efficient Food Safety Models

International Journal of Microbiology, Volume 2024, Issue 1, 2024.
Predictive microbiology is a rapidly evolving field that has gained significant interest over the years due to its diverse application in food safety. Predictive models are widely used in food microbiology to estimate the growth of microorganisms in food products.

Standardized network reconstruction of E. coli metabolism [PDF]

arXiv, 2013
We have created a genome-scale network reconstruction of Escherichia coli metabolism. Existing reconstructions were improved in terms of annotation standards, to facilitate their subsequent use in dynamic modelling. The resultant network is available from EcoliNet (http://ecoli.sf.net/).
