Strain intrinsic properties and environmental constraints together shape Escherichia coli dynamics and diversity over a twenty-year human gut time series

B. Condamine, T. Morel-Journel, F. Tesson, G. Royer, M. Magnan, A. Bernheim, E. Denamur, F. Blanquart, O. Clermont

This study tracks E. coli dynamics in a human gut over 20 years, showing how strain properties and environmental factors influence diversity and persistence.

Escherichia coli extra-intestinal population translocation in leukemia patients

J. Marin, V. Walewski, S. Dziri, M. Magnan, E. Denamur, E. Carbonnelle, A. Bridier-Nahmias

This study examines E. coli translocation from the gut to extra-intestinal compartments in immunosuppressed patients, finding compartment-specific selection patterns and mutator strains.

Dissemination of IncI plasmid encoding blaCTX-M-1 is not hampered by its fitness cost in the pig's gut.

M. Allain, A.-C. Maherault, B. Gachet, C. Martinez, B. Condamine, M. Magnan, I. Kempf, E. Denamur, L. Landraud

The study shows that an IncI plasmid encoding blaCTX-M-1 does not significantly reduce bacterial fitness in the pig gut, allowing its dissemination despite a minor growth rate difference.

Faecal carriage of ESBL-producing Escherichia coli in a remote region of Niger

H. Jacquier, B. Assao, F. Chau, O. Guindo, B. Condamine, M. Magnan, A. Bridier-Nahmias, N. Sayingoza-Makombe, A. Moumouni, A.-L. Page, C. Langendorf, M. Coldiron, E. Denamur, V. de Lastours

The paper uses whole genome sequencing to analyze ESBL-E. coli carriage in rural Niger, finding high prevalence of CTX-M-15 with chromosomal and plasmid integration.

Predictability shifts from local to global rules during bacterial adaptation

Alejandro Couce, M. Magnan, R. E. Lenski, O. Tenaillon

The study shows that short-term bacterial adaptation is predictable at the gene level, while long-term adaptation follows global statistical patterns.

Relationship between the composition of the digestive microbiota and the concentrations of opportunistic pathogens in intensive care patients.

C. Fontaine, L. Armand-Lefèvre, M. Magnan, A. Nazimoudine, J.-F. Timsit, E. RUPPE

The study examines the relationship between intestinal and tracheal microbiota composition and colonization by multidrug-resistant Gram-negative bacilli in ICU patients, finding no link between microbiota diversity and MDR-GNB abundance but a negative link with Enterococcus spp.
