Discriminating Between Living and Dead Bacteria With a Field‐Effect Transistor Based on Nano‐Channels

Small, Volume 22, Issue 54, 25 September 2026.
Bacterial viability is determined in a complex environment with a field‐effect biological transistor with a limit of detection of a single bacterium. Living, antibiotic‐treated, thermally denatured, and inhibited E. coli generate distinct electrical signatures, enabling label‐free single‐cell detection and providing new opportunities for rapid ...

Multiplex PCR to Diagnose Gastrointestinal Infections: Key Limitations in Interpretation

United European Gastroenterology Journal, Volume 14, Issue 7, September 2026.
ABSTRACT Multiplex polymerase chain reaction (PCR) panels are increasingly used for the evaluation of acute diarrhea, providing rapid and sensitive detection of a broad range of enteric pathogens. However, their widespread adoption has created important interpretive challenges for clinicians.

A roadmap for enterotoxigenic Escherichia coli vaccine development based on volunteer challenge studies

Human Vaccines & Immunotherapeutics, 2019
Enterotoxigenic Escherichia coli (ETEC) is a major cause of travelers’ diarrhea and of diarrhea among young children in developing countries. Experimental challenge studies in adult volunteers have played a pivotal role in establishing ETEC as an enteric

Heat-Stable Enterotoxin Secretions Assessed via ICP-MS Reveal Iron-Mediated Regulation of Virulence in CFA/I- and CS6-Expressing ETEC Isolates

Cells, 2023
Enterotoxigenic Escherichia coli (ETEC) are a significant cause of childhood diarrhea in low-resource settings. ETEC are defined by the production of heat-stable enterotoxin (ST) and/or heat-labile enterotoxin (LT), which alter intracellular cyclic ...

Identification of Potential Vaccine Strains of Escherichia coli Isolates From Diarrhoeic Calves

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study aimed to identify vaccine candidate Escherichia coli strains isolated from diarrheic calves. Faecal samples collected from 500 calves were analysed, and E. coli strains were isolated and characterized phenotypically and genotypically. Antibiotic resistance profiles, virulence‐associated genes and MLVA genotyping were used to select 20 ...

Recent Perspectives on Phytochemical Profile, Pharmacological Activities, and Industrial Applications of Guava (Psidium guajava)

Food Safety and Health, Volume 4, Issue 3, Page 542-560, July 2026.
Psidium guajava leaves contain potent bioactive compounds like quercetin, myricetin, and triterpenoids that show antioxidant, antidiabetic, anti‐inflammatory, and anticancer effects. They act by modulating NF‐κB, PPARγ, and α‐glucosidase and by inducing apoptosis and cell cycle arrest.
