In vitro activities of omadacycline, eravacycline, cefiderocol, apramycin, and comparator antibiotics against Acinetobacter baumannii causing bloodstream infections in Greece, 2020-2021: a multicenter study.

Resistance of Acinetobacter baumannii to multiple clinically important antimicrobials has increased to very high rates in Greece, rendering most of them obsolete. The aim of this study was to determine the molecular epidemiology and susceptibilities of A. baumannii isolates collected from different hospitals across Greece.

Characterization of 16S rRNA methylase genes in Enterobacterales and Pseudomonas aeruginosa in Athens Metropolitan area, 2015-2016.

The aim of this study was to characterize the 16S rRNA methylase (RMT) genes in aminoglycoside-resistant Enterobacterales and Pseudomonas aeruginosa isolates in 2015-2016 in hospitals in Athens, Greece. Single-patient, Gram-negative clinical isolates resistant to both amikacin and gentamicin (n = 292) were consecutively collected during a two-year period (2015-2016) in five tertiary care hospitals in Athens. RMT genes were detected by PCR.

In vitro activity of ceftolozane/tazobactam alone and in combination with amikacin against MDR/XDR Pseudomonas aeruginosa isolates from Greece.

Objectives: We evaluated the in vitro activity of ceftolozane/tazobactam and comparator agents against MDR non-MBL Pseudomonas aeruginosa isolates collected from nine Greek hospitals and we assessed the potential synergistic interaction between ceftolozane/tazobactam and amikacin.

Methods: A total of 160 non-MBL P. aeruginosa isolates collected in 2016 were tested for susceptibility to ceftolozane/tazobactam and seven comparator agents including ceftazidime/avibactam.

Dissemination of International Clone II Strains Coproducing OXA-23 Carbapenemase and 16S rRNA Methylase ArmA in Athens, Greece.

The aim of this study was to study the molecular epidemiology of 16S rRNA-methylase (RMT)-producing clinical isolates from hospitals in Athens, Greece. Single-patient clinical isolates, coresistant to amikacin and gentamicin ( = 347), from five tertiary care hospitals, were submitted to minimum inhibitory concentration determination and molecular testing for carbapenemase and RMT genes. resistant to amikacin and gentamicin, was isolated at participating institutions at a mean rate of 67.

An improved flow cytometric assay for detection and discrimination between malignant cells and atypical mesothelial cells, in serous cavity effusions.

Background: The aim of this study was to evaluate a flow cytometric assay for the detection of malignant effusions.

Methods: During the last 4-year period, 125 effusions suspicious for malignancy were prospectively analyzed by flow cytometry and conventional cytology. A three-step flow cytometric assay was performed, beginning with an initial informative panel of two protocols, containing SYTO-16, 7-AAD, CD71-PE, CD45-ECD, and CD66abce-FITC, CD64-PE, CD45-ECD, CD16-PECy5, CD14-PECy7, respectively.
