In the absence of a molecule that would collectively inhibit both metallo-β-lactamases and serine-reactive carbapenemases, containment of their genes is the main weapon currently available for confronting carbapenem resistance in hospitals. Cost-effective methodologies rapidly detecting carbapenemase-producing enterobacteria (CPE) would facilitate such measures. Herein, a low-cost CPE detection method was developed that was based on the direct colorimetry of the yellow shift caused by the accumulation of diketopiperazines-products of the acid-catalyzed imipenem oligomerization-induced by carbapenemase action on dense solutions of imipenem/cilastatin.

Extensive studies in cancer and other disease landscapes investigate the protective/pathogenic functions of dysregulated miRNAs, as well as their biomarker potential.

Reversal of carbapenemase-producing Klebsiella pneumoniae epidemiology from blaKPC- to blaVIM-harbouring isolates in a Greek ICU after introduction of ceftazidime/avibactam.
J Antimicrob Chemother
July 2019
Objectives: Our aim was to determine the epidemiology of bloodstream infections (BSIs) by carbapenemase-producing Klebsiella pneumoniae (CP-Kp) after the introduction of ceftazidime/avibactam in January 2018 among ICU patients.
Patients And Methods: All patients hospitalized at the ICU of the University General Hospital of Patras, Greece with CP-Kp BSI during 2015-18 were included. MICs of meropenem, fosfomycin, tigecycline and ceftazidime/avibactam (only for isolates from 2018) were determined by Etest, whereas for colistin, the broth microdilution method was applied.
Purpose: The aim of the present study was to analyze candidaemia's epidemiology (incidence, species distribution, and susceptibility rates) and antifungal consumption during a 9-year period.
Methods: All candidaemias recorded at The University General Hospital of Patras, Greece, between 2009 and 2017 were included. Candida isolates were identified using the germ tube test, API 20C AUX System, and/or Vitek-2 YST card.
