Microorganisms 2021, 9(9), 1823 Le pathotype Escherichia coli adhérent-invasif (AIEC) a été impliqué dans la pathogenèse des maladies inflammatoires de l’intestin en général et dans la maladie de Crohn (MC) en particulier. Les souches AIEC sont principalement caractérisées par leur capacité à adhérer aux cellules épithéliales intestinales et à les envahir. Cependant, les caractéristiques génétiques En savoir plus surAdherent-Invasive and Non-Invasive Escherichia coli Isolates Differ in Their Effects on Caenorhabditis elegans’ Lifespan[…]

Gut Microbes, Published online: 28 Mar 2021 The gastrointestinal tract is the main ecological niche in which Lactobacillus strains may provide health benefits in mammals. There is currently a need to characterize host-microbe interactions in space and time by tracking these bacteria in vivo. We combined noninvasive whole-body imaging with ex vivo fluorescence confocal microscopy En savoir plus surPersistence and dynamics of fluorescent Lactobacillus plantarum in the healthy versus inflamed gut[…]

Published: 22 February 2021, Microorganisms Toxic metals (such as lead, cadmium, and, to a lesser extent, aluminum) are detrimental to health when ingested in food or water or when inhaled. By interacting with heavy metals, gut and food-derived microbes can actively and/or passively modulate (by adsorption and/or seques- tration) the bioavailability of these toxins inside En savoir plus surAssessment of Pb(II), Cd(II), and Al(III) Removal Capacity of Bacteria from Food and Gut Ecological Niches: Insights into Biodiversity to Limit Intestinal Biodisponibility of Toxic Metals[…]

First published: 06 September 2019 https://doi.org/10.1002/9781119086420.ch6 Scanning probe microscopy methods have achieved nanoscopic views with unprecedented resolution, spanning scales from the atomic all the way to the tissue level. The scanning probe microscopy approach has been extended from scanning tunneling microscope (STM) to a large number of imaging modalities, such as atomic force microscopy (AFM), En savoir plus surCorrelative Microscopy Using Scanning Probe Microscopes[…]
