Characterisation of the effects of salicylidene acylhydrazide compounds on type three secretion in Escherichia coli O157:H7 [PDF]

, 2009
Recent work has highlighted a number of compounds that target bacterial virulence by affecting gene regulation. In this work, we show that small-molecule inhibitors affect the expression of the type III secretion system (T3SS) of <i>Escherichia ...

Effect of soiling agents on disinfection efficacy of a pulsed‐xenon UV lamp towards Listeria monocytogenes on stainless steel surfaces

The Canadian Journal of Chemical Engineering, EarlyView.
This study quantifies the effects of different soils found in the food processing environment on the efficiency of pulsed‐xenon UV disinfection. Abstract Listeria monocytogenes is a foodborne illness that poses a significant threat to human health in young, old, and immunocompromised persons and accordingly, prevention of Listeria contamination is of ...

Potential immunosuppressive effects of Escherichia coli O157:H7 experimental infection on the bovine host [PDF]

, 2016
Background: Enterohaemorrhagic Escherichia coli (EHEC), like E. coli O157:H7 are frequently detected in bovine faecal samples at slaughter. Cattle do not show clinical symptoms upon infection, but for humans the consequences after consuming contaminated ...

Mitigating Microbial Contamination in Fresh Fruits and Vegetables Using Ultraviolet C Irradiation: A Review

Food Safety and Health, EarlyView.
Although fresh produce is extremely perishable and contaminated, it is essential for good health. To eliminate important foodborne pathogens, this paper investigates UV‐C irradiation as a safe, nonthermal technique. UV dose, exposure duration, and product characteristics all affect effectiveness.

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

Mass Spectrometry Reviews, EarlyView.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

Multilocus-based phylogenetic analysis of extended-spectrum beta-lactamase Escherichia coli O157:H7 uncovers related strains between agriculture and nearby water sources

Journal of Infection and Public Health, 2020
This study aimed to uncover related strains of extended-spectrum beta-lactamase Escherichia coli O157:H7 between agricultural matrices (soil, manure and irrigation water) and nearby water sources using multilocus-based phylogenetic analysis.

Full‐length coding sequence analysis of the voltage‐gated sodium channel and acetylcholinesterase genes reveals target‐site mutations and acetylcholinesterase gene duplication in housefly (Musca domestica) populations in Japanese livestock barns

Medical and Veterinary Entomology, EarlyView.
We simultaneously analysed insecticide resistance mutations in VGSC and AChE using NGS and hybridization probe capture in houseflies collected from livestock facilities for the first time. Resistance mutations in both VGSC and AChE were detected in most wild populations, suggesting widespread distribution of resistance genes.
