Carbapenem-resistant carrier detection: a simple and efficient protocol.

Unlabelled: Timely detection of carbapenem-resistant (CRAB) carriers is essential to direct infection control measures. In this work, we aimed to develop a practical protocol to detect CRAB from screening samples. To choose a selective medium that detects CRAB with high sensitivity and specificity, 111 .

Hysteretic Responses of Skyrmion Lattices to Electric Fields in Magnetoelectric CuOSeO.

Electric field control of topologically nontrivial magnetic textures, such as skyrmions, provides a paradigm shift for future spintronics beyond the current silicon-based technology. While significant progress has been made by X-ray and neutron scattering studies, direct observation of such nanoscale spin structures and their dynamics driven by external electric fields remains a challenge in understanding the underlying mechanisms and harness functionalities. Here, using Lorentz transmission electron microscopy combined with electric and magnetic fields at liquid helium temperatures, we report the crystallographic orientation-dependent skyrmion responses to electric fields in thin slabs of magnetoelectric CuOSeO.

Large-scale WGS of carbapenem-resistant Acinetobacter baumannii isolates reveals patterns of dissemination of ST clades associated with antibiotic resistance.

Objectives: To describe the population genetics and antibiotic resistance gene distribution of carbapenem-resistant Acinetobacter baumannii (CRAB) isolates causing infections in three Mediterranean countries.

Methods: Isolates were collected during the 2013-17 AIDA clinical trial in six hospitals in Israel, Greece and Italy. WGS, bioinformatic characterization and antibiotic resistance profiling were performed.

OXA-900, a Novel OXA Sub-Family Carbapenemase Identified in , Evades Detection by Commercial Molecular Diagnostics Tests.

Using whole-genome sequencing and cloning of the target gene, we identified carbapenemase, a novel belonging to a distant and distinct sub-family of . The plasmid-mediated gene was identified in a isolate with elevated carbapenem MICs that evaded detection by commercial DNA-based methods. The novel gene, an OXA-48 family carbapenem-hydrolyzing class D β-lactamase, OXA-900, likely originates from marine environmental .

Scaling, rotation, and channeling behavior of helical and skyrmion spin textures in thin films of Te-doped CuOSeO.

Topologically nontrivial spin textures such as vortices, skyrmions, and monopoles are promising candidates as information carriers for future quantum information science. Their controlled manipulation including creation and annihilation remains an important challenge toward practical applications and further exploration of their emergent phenomena. Here, we report controlled evolution of the helical and skyrmion phases in thin films of multiferroic Te-doped CuOSeO as a function of material thickness, dopant, temperature, and magnetic field using in situ Lorentz phase microscopy.
