Abstract Root cause analysis following microbial water contamination events typically relies upon the collection of large sample volumes. Dead‐end ultrafiltration (DEUF) is an efficient method for sampling and transporting up to 100 L of water from field environments. A single‐lab validation (SLV) using DEUF to recover Shiga toxin‐producing Escherichia

Quantitative detection and characterization of Shiga toxin-producing Escherichia coli O157 and non-O157 in raw vegetables by MPN-PCR in Malaysia [PDF]
Foodborne diseases are mainly caused by bacterial contamination which can lead to severe diarrhea. This study aimed to detect the presence of Shiga toxin-Producing Escherichia coli O157, Escherichia coli non-O157 and virulence gene in raw vegetables.

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

CsrA and its regulators control the time-point of ColicinE2 release in Escherichia coli [PDF]
The bacterial SOS response is a cellular reaction to DNA damage, that, among other actions, triggers the expression of colicin - toxic bacteriocins in Escherichia coli that are released to kill close relatives competing for resources. However, it is largely unknown, how the complex network regulating toxin expression controls the time-point of toxin ...

Quick and Sensitive Two‐Plex Electrochemical Platform for Pathogen Detection in Water
A portable electrochemical biosensor detects Salmonella Typhimurium and E. coli O157 in drinking water within five minutes. The sensor uses antibody‐functionalized electrodes with a detection limit below 1 CFU/mL. It shows high sensitivity, reproducibility, and field applicability, offering a fast and reliable tool for early pathogen detection to ...
