Occurrence of Escherichia coli virulence genes in feces of wild birds from Central Italy

Asian Pacific Journal of Tropical Medicine, 2019
Objective: To investigate the potential role of wild birds as fecal spreaders of enteropathogenic, enterohemorrhagic and Shiga-toxins producing Escherichia coli (E. coli), enteropathogenic E. coli, enterohemorrhagic E.

Microarray-based screening of differentially expressed genes of E. coli O157:H7 Sakai during preharvest survival on butterhead lettuce [PDF]

, 2016
Numerous outbreaks of Escherichia coli O157:H7 have been linked to the consumption of leafy vegetables. However, up to the present, little has been known about E.

Colonic Barrier Dysfunction and Inflammation Induced by Nano‐/Micro‐Plastics Fibers in Mice via the FAK/NF‐κB/iNOS and TLR4/NF‐κB/iNOS Pathways

Journal of Applied Toxicology, EarlyView.
ABSTRACT As emerging environmental contaminants, nano‐ and micro‐plastics (NMPs) have drawn increasing research attention due to potential hazards to organisms. Particle shape is a key factor influencing the toxic effects of NMPs, and NMPs of different shapes cause varying degrees of tissue damage. We investigated the specific mechanisms of polystyrene

Decrease in Shiga toxin expression using a minimal inhibitory concentration of rifampicin followed by bactericidal gentamicin treatment enhances survival of Escherichia coli O157:H7-infected BALB/c mice

Annals of Clinical Microbiology and Antimicrobials, 2011
Background Treatment of Escherichia coli O157:H7 infections with antimicrobial agents is controversial due to an association with potentially fatal sequelae.

Diarrheagenic toxins in stool correlate to drinking water from improved water sources in Ethiopia

Environmental Challenges, 2022
Escherichia coli toxins are the most common types found in association with disease in E. coli bacteria. They are found in nearly all pathogenic E. coli bacteria either released from the bacteria or E. coli cell or both transmitted via the orofecal route.

Enterohemorrhagic Escherichia coli with particular attention to the German outbreak strain O104:H4 [PDF]

, 2012
This review deals with the epidemiology and ecology of enterohemorrhagic Escherichia coli (EHEC), a subset of the verocytotoxigenic Escherichia coli (VTEC), and subsequently discusses its public health concern.

Microbial communities and functional diversity in seafood

JSFA reports, EarlyView.
Abstract Functional diversity encompasses ecosystem processes that enhance adaptability to environmental change. This study explores the diversity of microorganisms associated with seafood. In this paper, we present our knowledge of microbial diversity in relation to seafood.

Simple oxidation of pyrimidinylhydrazones to triazolopyrimidines and their inhibition of Shiga toxin trafficking [PDF]

, 2010
The oxidative cyclisation of a range of benzothieno[2,3-d]pyrimidine hydrazones (7a–j) to the 1,2,4-triazolo[4,3-c]pyrimidines (8a–j) catalysed by lithium iodide or to the 1,2,4-triazolo[1,5-c]pyrimidines (10a–j) with sodium carbonate is presented.

TOXINS AND ANTITOXINS OF BACILLUS DYSENTERIÆ SHIGA [PDF]

Journal of Experimental Medicine, 1920
With the methods which have been described we have separated an exotoxin and an endotoxin from cultures of the Shiga dysenteric bacillus. The study of the nature and effect of the poison of this microorganism is thus simplified. The two toxins are physically and biologically distinct.

Quantifying Protein–Glycan Interactions Using Native Mass Spectrometry

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Interactions between glycan‐binding proteins (GBPs) and carbohydrates (glycans) are essential to many biological processes relevant to human health and disease. For most GBPs, however, their glycan interactome—the repertoire of glycans recognized and their specificities—is poorly defined.
