Applying elastic deformation can tune a material’s physical properties locally and reversibly. Spatially modulated lattice deformation can create a bandgap gradient, favoring photogenerated charge separation and collection in optoelectronic devices. These advantages are hindered by the maximum elastic strain that a material can withstand before breaking. Nanomaterials derived by exfoliating...

The inoculum effect of Escherichia coli expressing mcr-1 or not on colistin activity in a murine model of peritonitis

Fantin, B. ; Poujade, J. ; Grégoire, N. ; Chau, F. ; Roujansky, A. ; Kieffer, Nicolas ; Berleur, M. ; Couet, W. ; Nordmann, Patrice

In: Clinical Microbiology and Infection, 2019, vol. 25, no. 12, p. 1563.e5-1563.e8

Colistin often remains the last resort antibiotic active against carbapenemase- producing Enterobacteriaceae. However, while in vitro inoculum effect has been reported, therapeutic relevance of this phenomenon remains questioned.Methods: Ten E. coli strains were used that included the wild-type CFT073 and its transconjugant CFT073-MCR-1 and eight susceptible clinical isolates. Mice with ...
