Extended-spectrum beta-lactamase-producing Escherichia coli and Klebsiella pneumoniae from human carriage, the human-polluted environment, and food: Molecular epidemiology of two prospective cohorts in five European metropolitan areas Open
Objectives For 475 ESBL-producing Escherichia coli (ESBL-Ec), and 171 ESBL-producing Klebsiella pneumoniae (ESBL-Kp) collected from human carriers, the human-polluted (hp)-environment, and food: (i) to compare the antimicrobial resistance …

Occurrence of Enterobacterales producing extended-spectrum β-lactamases in organic and conventional food collected in France Open
The spread of extended-spectrum β-lactamase-producing Enterobacterales (ESBL-PE) is a major public health concern, best addressed through a One Health approach that considers the interconnectedness of human, animal, and environmental reser…

High prevalence of Pseudomonas aeruginosa carriage in residents of French and German long-term care facilities Open
We found an unexpected high prevalence of PA intestinal carriage in LTCF residents mainly associated with individual-level factors. Our study revealed a polyclonal PA population structure suggesting that individual acquisition is more freq…

One Health compartmental analysis of ESBL-producing <i>Escherichia coli</i> on Reunion Island reveals partitioning between humans and livestock Open
Background Extended-spectrum β-lactamase-producing Escherichia coli (ESBL-Ec) is a major cause of infections worldwide. An understanding of the reservoirs and modes of transmission of these pathogens is essential, to tackle their increasin…

Populations of extended-spectrum β-lactamase-producing Escherichia coli and Klebsiella pneumoniae are different in human-polluted environment and food items: a multicentre European study Open
We found a very limited connection between ESBL-Ec and ESBL-Kp populations retrieved in food items and from hp-environments and blaESBL. This suggests that human-to-human contamination, rather than the food chain, is possibly the most freq…

Epidémiologie des bacilles à Gram négatif dans la communauté, l’environnement et la nourriture Open
Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa are Gram-negative bacilli frequently involved in nosocomial infections. Their dissemination in health care systems has been well characterized but the intestinal carriage a…

High Prevalence of Human-Associated Escherichia coli in Wetlands Located in Eastern France Open
Escherichia coli that are present in the rivers are mostly brought by human and animal feces. Contamination occurs mostly through wastewater treatment plant (WWTP) outflows and field amendment with sewage sludge or manure. However, the sur…

Fourier-Transform InfraRed Spectroscopy Can Quickly Type Gram-Negative Bacilli Responsible for Hospital Outbreaks Open
The typing of epidemic bacterial pathogens in hospitals relies on DNA-based, expensive, and time-consuming techniques, that are often limited to retrospective studies. However, the quick identification of epidemic pathogens in the routine …

Occurrence and ecological determinants of the contamination of floodplain wetlands with Klebsiella pneumoniae and pathogenic or antibiotic-resistant Escherichia coli. Open
The survival and multiplication of human pathogenic and antibiotic-resistant bacteria in ecosystems is of increasing concern but has been little explored. Wetlands can be contaminated by water fluxes from rivers and may present environment…

Genomic characterization of a local epidemic Pseudomonas aeruginosa reveals specific features of the widespread clone ST395 Open
Pseudomonas aeruginosa is a ubiquitous opportunistic pathogen with several clones being frequently associated with outbreaks in hospital settings. ST395 is among these so-called ‘international’ clones. We aimed here to define the biologica…
