IncC plasmid genome rearrangements influence the vertical and horizontal transmission tradeoff in Escherichia coli

M. Allain, T. Morel-Journel, B. Condamine, B. Gibeaux, B. Gachet, R. GSCHWIND, E. Denamur, L. Landraud

This study shows that IncC plasmid genome rearrangements enhance horizontal transmission while maintaining bacterial fitness, suggesting a strategy for plasmid dissemination.

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.

The cnf1 gene is associated to an expanding Escherichia coli ST131 H30Rx/C2 sublineage and confers a competitive advantage for host colonization

L. L. TSOUMTSA MEDA, L. LANDRAUD, S. PETRACCHINI, S. DESCORPS-DECLERE, E. PERTHAME, M.-a. NAHORI, L. RAMIREZ FINN, M. A. INGERSOLL, R. PATINO-NAVARETE, P. GLASER, O. DUSSURGET, E. DENAMUR, A. METTOUCHI, E. LEMICHEZ

This study identifies the cnf1 gene's role in enhancing host colonization by ST131-H30Rx/C2 E. coli, driving its global spread alongside antibiotic resistance genes.
