[In vitro activity of fosfomycin, alone or in combination, against clinical isolates of carbapenem resistant Pseudomonas aeruginosa].

Introduction: The increase in microorganisms showing patterns of multi-drug resistance or even pan-drug resistance is of growing concern. Fosfomycin (FO) is well known to be active against a wide variety of microorganisms, including highly resistant strains of Pseudomonas aeruginosa (P. aeruginosa), and can also synergistically act with other molecules.

Identification of clinical yeasts by Vitek MS system compared with API ID 32 C.

We performed a clinical evaluation of the Vitek MS matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS) system with the commercial database version 2.0 for rapid identification of medically important yeasts as compared with the conventional phenotypic method API ID 32 C. We tested 161 clinical isolates, nine isolates from culture collections and five reference strains.
