Fourier transform infrared spectroscopy as a new tool for surveillance in local stewardship antimicrobial program: a retrospective study in a nosocomial Acinetobacter baumannii outbreak.

The aim of our study is to determine the discriminatory power of the Fourier transform infrared spectroscopy (FTIR), using multi-locus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE) as molecular typing references. The study included seventeen isolates (OXA-23- and OXA-58-producing Acinetobacter baumannii) previously recovered from clinical specimens during the period May 2010-April 2011. Molecular typing was performed by PFGE and MLST.

Invasive Fusariosis in Nonneutropenic Patients, Spain, 2000-2015.

Invasive fusariosis (IF) is associated with severe neutropenia in patients with concurrent hematologic conditions. We conducted a retrospective observational study to characterize the epidemiology of IF in 18 Spanish hospitals during 2000-2015. In that time, the frequency of IF in nonneutropenic patients increased from 0.

Hepatitis C virus core antigen in the management of patients treated with new direct-acting antivirals.

We evaluated the utility of Architect core antigen assay® Abbott Diagnostics (HCVAg) for monitoring patients with HCV infection and compared to HCV-RNA quantification (Cobas Ampliprep TaqMan-Roche Diagnostics). Samples from 262 patients were studied. Mean baseline HCV RNA and HCVAg levels were similar for responders (6.

[First report of invasive fungal disease by Candida fabianii in a non-neonatal paediatric patient].

Background: Invasive fungal diseases have increased in recent years. Candida species are the most common aetiology. Candida albicans, Candida parapsilosis, Candida tropicalis, Candida glabrata and Candida krusei are the cause of most of them.

Description of the OXA-23 β-lactamase gene located within Tn2007 in a clinical isolate of Acinetobacter baumannii from Spain.

A carbapenem-resistant Acinetobacter baumannii expressing blaOXA-23 was recovered from an intensive care unit patient in a third-level hospital from Spain. Genetic analysis showed the association of this carbapenemase with the transposon Tn2007 located in a plasmid of 10 kb. The isolate was classified as ST-1.

[Fungemia due to Trichosporon asahii in a patient with hematological malignancy].

Background: Trichosporonosis is an opportunistic infection caused by the genus Trichosporon. The majority of cases of invasive trichosporonosis occurs in immunocompromised individuals.

Case Report: We describe a case of disseminated infection by Trichosporon asahii in a hematology patient.
