Global Distribution and Comparative Resistance Profiles of Escherichia coli Isolated From Bovine Meat and Meat Products: Evidence From Network Meta‐Analysis

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
Schematic overview of the study and its principal findings. E. coli isolated from bovine meat and meat products was evaluated for antimicrobial resistance using Bayesian network meta‐analysis. The graphical abstract highlights the antimicrobial resistance ranking based on SUCRA, showing high resistance to penicillin, doxycycline, amoxicillin ...

LPS and Stx1-treated ASTs release factors that increase platelet activation and adhesion to HUVECd.

, 2012
Platelets or HUVECd were stimulated with CM-Control, CM−LPS, CM−Stx1 or CM−LPS+Stx1. After 1.5 h density expression of P-selectin and the % of activated platelets was determined by FACS (A and B).

Multi‐omics biomarkers for intestinal infection and inflammation in inflammatory bowel disease: Current evidence, translational challenges, and diagnostic opportunities

Interdisciplinary Medicine, Volume 4, Issue 4, July 2026.
Prospective multi‐site cohorts, multi‐omics profiling, and computational analysis may help identify biomarker patterns across clinical settings in IBD and superimposed infections. With further mechanistic and clinical validation, these signals could support the development of practical multi‐analyte tools for more precise diagnosis and management ...

Shiga Toxin 1, as DNA Repair Inhibitor, Synergistically Potentiates the Activity of the Anticancer Drug, Mafosfamide, on Raji Cells

Toxins, 2013
Shiga toxin 1 (Stx1), produced by pathogenic Escherichia coli, targets a restricted subset of human cells, which possess the receptor globotriaosylceramide (Gb3Cer/CD77), causing hemolytic uremic syndrome.

Neutralization of Stx1 holotoxin by the plantibody.

, 2013
Stx1 holotoxin was pre-treated with an extract of dimer Tg plants, an extract of a wild-type plants (WT), or control IgA (TEPC 15) for 1 h, and then the mixture was added to Stx1-sensitive cells. A. Cell viability assay. Vero cells were cultured for 48 h
