Bovine non-O157 Shiga toxin 2-containing Escherichia coli isolates commonly possess stx(2-EDL933) and/or stx(2vhb) subtypes [PDF]

, 2003
stx(2) genes from 138 Shiga toxin-producing Escherichia coli (STEC) isolates, of which 127 were of bovine origin (58 serotypes) and 11 of human origin (one serotype; O113:H21), were subtyped.

Characterization of STX-S cells and exosomes expressing spike.

, 2023
(A) Diagram of STX-S construct. (B) High expression of spike was detected on cell surface (blue) by flow cytometry. Parent, non-engineered 293F cells (light green) do not express SARS-CoV-2 spike protein, as expected.

In Vivo Transduction of an Stx-Encoding Phage in Ruminants [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACTWe assessed the ability of a kanamycin-marked Stx phage to move into a commensal, ovineEscherichia colistrain in the ruminant gastrointestinal tract. Transduction was detected in 19/24 sheep tested, resulting in the recovery of 47 transductants.

Occurrence of Multiple stx1 Genes and Rare Genomic Variation in stx1 Shiga Toxin-Producing Escherichia coli

Microorganisms
Shiga toxin-producing Escherichia coli are important foodborne pathogens. There are several subtypes of the Shiga toxin Stx known, with Stx2 (a–o) being more diverse than Stx1 (a, c, d).

⁶⁰Co irradiation of Shiga toxin (Stx)-producingEscherichia coliinduces Stx phage [PDF]

FEMS Microbiology Letters, 2003
Shiga toxin (Stx)-producing Escherichia coli (STEC), an important cause of hemolytic uremic syndrome, was completely killed by (60)Co irradiation at 1 x l0(3) gray (1 kGy) or higher. However, a low dose of irradiation (0.1-0.3 kGy) markedly induced Stx phage from STEC. Stx production was observed in parallel to the phage induction.

Insulinotropic effect of the non-steroidal compound STX in pancreatic β-cells. [PDF]

PLoS ONE, 2012
The non-steroidal compound STX modulates the hypothalamic control of core body temperature and energy homeostasis. The aim of this work was to study the potential effects of STX on pancreatic β-cell function.

Tetrodotoxin/Saxitoxin Accumulation Profile in the Euryhaline Marine Pufferfish Chelonodontops patoca

Toxins, 2023
Marine Takifugu pufferfish, which naturally possess tetrodotoxins (TTXs), selectively take up and accumulate TTXs, whereas freshwater Pao pufferfish, which naturally possess saxitoxins (STXs), selectively take up and accumulate STXs.

Biofilm as an Environment for Dissemination of stx Genes by Transduction [PDF]

Applied and Environmental Microbiology, 2013
ABSTRACT Dissemination of Shiga toxin (Stx)-encoding bacteriophages is the most likely mechanism for the spread of Stx-encoding genes and the emergence of new Stx-producing Escherichia coli (STEC). Biofilm has been reported to be a place where horizontal gene transfer by plasmid conjugation and DNA ...
