Pathogenic Escherichia coli Virulome in Top Soil Improvers and Irrigation Waters Devoted to Leafy Vegetable Production: Hazard Assessment From a Case Study in Italy

open access: yesFood Safety and Health, EarlyView.
Escherichia coli pathotype virulotyping to assess if combined top soil improver and water inputs would potentially lead to hybrid strains with shuffled virulence features in ready‐to‐eat vegetables. This is to support the transition toward safe and sustainable food production systems.

Transient drift of Escherichia coli under diffusing Step nutrient profile [PDF]

open access: yesPhys. Rev. E 98, 052413 (2018), 2018
Bacteria such as Escherichia coli (E. coli) exhibit biased motion if kept in a spatially non-uniform chemical environment. Here, we bring out unique time-dependent characteristics of bacterial chemotaxis, in response to a diffusing spatial step ligand profile.

Polymerase Chain Reaction Assay for Detection of Escherichia coli O157:H7 and Escherichia coli O157:H−

open access: yesJournal of Food Protection, 2002
The DNA band patterns generated by polymerase chain reaction (PCR) using the du2 primer and template DNAs from various strains of Escherichia coli and non-E. coli bacteria were compared. Among three to five prominent bands produced, the three bands at about 1.8, 2.7, and 5.0 kb were detected in all of the E. coli O157 strains tested. Some nonpathogenic

Occurrence, Molecular Detection and Antibiotic Resistance Profile of Escherichia coli O157:H7 Isolated from Ready-to-Eat Vegetable Salads in Iran

open access: yesPharmaceutical Sciences, 2016
Background: Escherichia coli O157:H7 is one of the high risk bacteria, found in foods, especially in ready-to-eat products, which causes many disorders such as hemorrhagic colitis, hemolytic uremic syndrome and dysentery in humans.
