Infections caused by ceftolozane-tazobactam and ceftazidime-avibactam-resistant P. aeruginosa infections are an emerging concern. We aimed to analyze the underlying ceftazidime-avibactam resistance mechanisms in all multidrug-resistant or extensively drug-resistant (MDR/XDR) isolates recovered during 1 year (2020) from patients with a documented infection. Fifteen showing were evaluated. Clinical conditions, previous positive cultures, β-lactams received month reviewed for each patient. MICs...

The ability of MALDI-TOF for the identification nontuberculous mycobacteria (NTM) has improved recently thanks to updated databases and optimized protein extraction procedures. Few multicentre studies on reproducibility have been performed so far, none mycobacteria. aim this study was evaluate NTM in 15 laboratories 9 European countries. A total 98 clinical isolates were grown Löwenstein-Jensen. Biomass collected tubes with water ethanol, anonymized sent out participating laboratories....

ABSTRACT Pseudomonas aeruginosa is a major nosocomial pathogen commonly involved in multidrug-resistant (MDR) infections that are very difficult to treat. Imipenem/relebactam new carbapenem/β-lactamase inhibitor combination with robust activity against P. . However, resistance increasingly reported, and rapid detection is, therefore, crucial so appropriate treatments can be prescribed. We have developed MALDI TOF-MS-based method accurately predict the presence of carbapenemases using...

In this study, we evaluate the performance of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) for rapid detection carbapenemase activity in Enterobacterales clinical microbiology laboratories during a multicenter networking validation study. The study was divided into three different stages: “software design,” “intercenter evaluation,” and “clinical validation.” First, standardized procedure with an online software data analysis designed....

A rapid and sensitive (100%) matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) assay was developed to detect OXA-48-type producers, using 161 previously characterized clinical isolates. Ertapenem monitored carbapenem resistance, temocillin included in the as a marker for OXA-48-producers. Structural analysis is described. Data are obtained within 60 min.

The increasing emergence of carbapenemase-producing Klebsiella pneumoniae (CPK) isolates is a global health alarm. Rapid methods that require minimum sample preparation and rapid data analysis are urgently required. Matrix-assisted laser desorption ionization-time flight mass spectrometry (MALDI-TOF MS) has recently been used by clinical laboratories for identification antibiotic-resistant bacteria; however, discrepancies have arisen regarding biological technical issues. aim this study was...
