Identification of Shiga-Toxin-Producing Shigella Infections in Travel and Non-Travel Related Cases in Alberta, Canada

Toxins, 2021
It has long been accepted that Shiga toxin (Stx) only exists in Shigella dysenteriae serotype 1. However, in recent decades, the presence of Shiga toxin genes (stx) in other Shigella spp. have been reported. We screened 366 Shigella flexneri strains from

Pathways of Protein Secretion in Prokaryotes and Eukaryotes: Molecular Mechanisms, Biological Functions, and Therapeutic Opportunities

MedComm, Volume 7, Issue 6, June 2026.
This graphical abstract delineates noncanonical protein secretion systems across eukaryotes and prokaryotes. Eukaryotic UcPS covers four ER–Golgi bypass pathways, enabling rapid leaderless protein export via direct transmembrane translocation or vesicle‐mediated release.

A new multiplex PCR for differential identification of Shigella flexneri and Shigella sonnei and detection of Shigella virulence determinants [PDF]

, 2010
Most of the multiplex PCR (mPCR) used to identify Shigella do not discriminate between Shigella species or serotypes. We designed a mPCR to differentiate between S. flexneri and S.

Synthesis and utilization of siderophores by Shigella flexneri [PDF]

Journal of Bacteriology, 1980
Strains of Shigella flexneri secrete a hydroxamate-type siderophore when grown in low-iron media. This hydroxamate appears to be identical with aerobactin, a siderophore synthesized by Aerobacter aerogenes. In contrast to other enteric bacteria, S. flexneri did not produce detectable phenolate siderophores, although it could utilize an exogenously ...

Septins in the Middle—Makers and Breakers of Membrane Contact Sites

Journal of Neurochemistry, Volume 170, Issue 6, June 2026.
Septins are a family of GTP‐binding proteins that assemble into heteromeric oligomers and polymers, associating with specific membrane domains and organelles according to their subunit composition. Growing evidence places septins at membrane contact sites (MCS) — key hubs for intracellular communication that mediate exchange of ions, lipids, and ...

Antibiogram Pattern of Shigella flexneri: Effect of BioField Treatment [PDF]

, 2015
Shigellosis is a major public health burden in India and its neighboring countries due to infection of Shigella species. The current study was attempted to investigate the effect of biofield treatment on Shigella flexneri (S.

Fermented Foods and Beverages of Ethiopia: Substrates, Traditional Preparation Techniques, and Nutritional Quality

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
Traditional Ethiopian fermented foods and beverages such as Injera, Kocho, and Tella provide important health benefits, including improved nutrient bioavailability, gut health, and digestibility. However, challenges such as lack of standardization, insufficient documentation, and economic constraints limit their wider development and commercialization.

Molecular and Cellular Mechanisms of Shigella flexneri Dissemination [PDF]

Frontiers in Cellular and Infection Microbiology, 2016
The intracellular pathogen Shigella flexneri is the causative agent of bacillary dysentery in humans. The disease is characterized by bacterial invasion of intestinal cells, dissemination within the colonic epithelium through direct spread from cell to cell, and massive inflammation of the intestinal mucosa. Here, we review the mechanisms supporting S.

Phytochemical content, antioxidant and antibacterial properties of Typhonium flagelliforme cultivated via soil and hydroponic methods

JSFA reports, Volume 6, Issue 5, Page 179-192, May 2026.
Abstract Background Typhonium flagelliforme is a medicinal herb in the Araceae family, widely distributed in Southeast Asia. This study aimed to evaluate the effects of hydroponic and soil‐based cultivation systems on the phytochemical content and bioactivity of T. flagelliforme. Results Using liquid chromatography‐mass spectrometry (LC‐MS) analysis, 9
