Drug Resistance without a cost? Common and uncommon routes to fosfomycin resistance in Uropathogenic Escherichia coli

T. Bermudez, J. R. Brannon, N. Dudipala, S. Reasoner, G. H. Morales, M. A. Wiebe, M. Cecala, C. J. Beebout, O. Amir, M. Hadjifrangiskou

This study identifies multiple routes to fosfomycin resistance in uropathogenic E. coli that do not impair pathogenesis, suggesting a need to revise AST guidelines.

Mapping Niche-specific Two-Component System Requirements in Uropathogenic Escherichia coli

J. R. Brannon, S. Reasoner, T. Bermudez, T. L. Dunigan, M. A. Wiebe, C. J. Beebout, T. L. Ross, A. Bamidele, M. Hadjifrangiskou

This study identifies niche-specific two-component systems (TCSs) in uropathogenic Escherichia coli (UPEC) critical for colonization of the bladder, kidneys, and vagina during infection.

Serine Deamination as a New Acid Resistance Mechanism in Escherichia coli

M. A. Wiebe, J. R. Brannon, B. D. Steiner, A. Bamidele, A. C. Schrimpe-Rutledge, S. G. Codreanu, S. D. Sherrod, J. McLean, M. Hadjifrangiskou

This study identifies L-serine deamination as a novel acid resistance mechanism in E. coli, where serine is converted to pyruvate and ammonia to enhance acid tolerance during stationary phase.

Balanced Input from the tRNA Prenyltransferase MiaA Controls the Stress Resistance and Virulence Potential of Extraintestinal Pathogenic Escherichia coli

M. G. Blango, B. A. Fleming, W. M. Kincannon, A. Tran, A. J. Lewis, C. W. Russell, Q. Zhou, L. M. Baird, J. R. Brannon, C. J. Beebout, V. Bandarian, M. Hadjifraniskou, M. T. Howard, M. A. Mulvey

This study shows that MiaA, but not MiaB, is critical for the fitness and virulence of ExPEC, and that stress can alter MiaA expression to affect translation and proteome composition.

Identification and characterization of OmpT-like proteases in uropathogenic Escherichia coli clinical isolates

I. Desloges, J. A. Taylor, J.-M. Leclerc, J. R. Brannon, A. Portt, J. D. Spencer, K. Dewar, G. T. Marczynski, A. Manges, S. Gruenheid, H. Le Moual, J.-L. Thomassin

The paper measures OmpT protease activity in UPEC isolates and finds higher activity in symptomatic UTI strains, with some isolates also expressing an additional ompT-like gene, arlC.

Respiratory heterogeneity shapes biofilm formation and host colonization in uropathogenic Escherichia coli

C. J. Beebout, A. R. Eberly, S. H. werby, S. Reasoner, J. R. Brannon, S. De, M. J. Fitzgerald, M. M. Huggins, D. B. Clayton, L. Cegelski, M. Hadjifrangiskou

This study shows that respiratory heterogeneity in uropathogenic E. coli influences biofilm formation and host colonization through differential expression of cytochrome oxidases.
