HlyF, an underestimated virulence factor of uropathogenic Escherichia coli

C. V. Chagneau, D. Payros, A. Goman, C. Goursat, L. David, M. Okuno, P.-J. Bordignon, C. Seguy, C. Massip, P. Branchu, Y. Ogura, J.-P. Nougayrede, M. Marenda, E. Oswald

The paper identifies HlyF as a virulence factor in UPEC strains associated with severe UTIs and urosepsis, showing its link to plasmid-mediated virulence and antimicrobial resistance.

Oxygen concentration modulates colibactin production

N. Bossuet, C. Guyonnet, C. Chagneau, M. Tang-Fichaux, M. Penary, D. Loubet, P. Branchu, E. Oswald, J.-P. Nougayrede

This study shows that colibactin production in E. coli is maximal under anoxic conditions and decreases with oxygen concentration, suggesting adaptation to the intestinal environment.

Insights into the acquisition of the pks island and production of colibactin in the Escherichia coli population

F. Auvray, A. Perrat, Y. Arimizu, C. V. Chagneau, N. Bossuet-Greif, C. Massip, H. Brugere, J.-P. Nougayrede, T. Hayashi, P. Branchu, Y. Ogura, E. Oswald

This study identifies the distribution and functionality of the pks island in E. coli strains, showing its presence across multiple phylogroups and its role in colibactin production.

Ecological niche adaptation of a bacterial pathogen associated with reduced zoonotic potential

M. Kirkwood, P. Vohra, M. Bawn, G. Thilliez, H. Pye, J. Tanner, C. Chintoan-Uta, P. Branchu, L. Petrovska, T. J. Dallman, N. Hall, M. Stevens, R. A. Kingsley

This paper identifies a bacterial pathogen variant, S. Typhimurium U288, that has adapted to pigs, resulting in reduced zoonotic potential compared to ST34.

SGI-4 in monophasic Salmonella Typhimurium ST34 is a novel ICE that enhances resistance to copper

P. Branchu, O. J. Charity, M. Bawn, G. Thilliez, T. J. Dallman, L. Petrovska, R. Kingsley

The paper identifies SGI-4, a genomic island in Salmonella Typhimurium ST34, which enhances copper resistance through the silCBA efflux pump and suppresses copper-dependent induction of the pco system.
