Epidemiología molecular y genómica de aislados resistentes de Pseudomonas aeruginosa de origen hospitalario.
2019
Pseudomonas aeruginosa es un patógeno frecuente en entornos hospitalarios que acumula multitud de resistencias a antibióticos. Ante la dificultad de encontrar tratamiento efectivo, los pacientes están mucho tiempo colonizados y aumenta la probabilidad de transmisión. El principal objetivo del presente trabajo ha sido mostrar cómo el estudio evolutivo a nivel de genomas completos puede ser útil para la detección de transmisiones a diferentes niveles. Se decidió aplicar la misma metodología de reconstrucción de la filogenia a partir de las variantes encontradas en genomas completos que además se dataron por métodos bayesianos. Para ello, hemos contado con muestras de P. aeruginosa multirresis…
L’INFORMAZIONE E LA FORMAZIONE DEL SANITARIO NELLE INFEZIONI NOSOCOMIALI: LA NOSTRA ESPERIENZA
2013
Gli Autori riportano i risultati ottenuti dalla somministrazione di un questionario, nel contesto siciliano dei Policlinici Universitari di Palermo e Messina, a sanitari operanti nel campo della terapia intensiva, selezionando e analizzando i quesiti maggiormente implicati nelle tematiche inerenti il clinical risk management delle IN, individuandone specifiche carenze a carico dei singoli professionisti e della struttura ospedaliera. È stato evidenziato che, sebbene siano già presenti specifici protocolli, nonché linee guida in materia, essi non trovano ancora un adeguato spazio nella realtà quotidiana di gestione del malato a causa di una generale inadeguatezza dell’informazione e della fo…
Phenotypic and genetic analysis of biofilm formation by Staphylococcus epidermidis.
2012
Objective. The most important virulence factor of Staphylococcus epidermidis is their capability to form a biofilm on the surfaces of implanted medical devices. The accumulative phase of biofilm formation is linked to the production of intercellular adhesin encoded by the icaADBC operon and accumulation-associated protein by the aap gene. The aim of the study was to investigate biofilm formation phenotypically and genetically in clinical strains of S. epidermidis in comparison with commensal strains. Material and Methods. The study was carried out in 4 hospitals in Riga, Latvia. In total, 105 clinical strains of Staphylococcus epidermidis isolated from patients’ blood (n=67) and intravenous…
Development of a modified DNA extraction method for pulsed-field gel electrophoresis analysis of Staphylococcus aureus and enterococci without using …
2010
A modified pulsed-field gel electrophoresis (PFGE) protocol was developed and applied to clinical isolates of Staphylococcus aureus and enterococci to reduce the cost of using lysostaphin. This protocol reduces the expenses of PFGE typing of S. aureus and enterococci as it removes the use of lysostaphin during the spheroplast formation from these bacteria.
La représentation sociale de l'hygiène chez les professionnels de santé : Intérêt du recueil par entretien et de l'analyse discursive des opérateurs …
2009
This study deals with professional representations. The goal is to show the representation of hygiene by health care workers: Nurses (N) and Health Care Aides (HCA). Method follows the BSC (Bases Cognitive Schemes) procedure, explicative interviews substitute to the evaluation task. An analysis of associative words points out that for HCA hygiene is associated with acts linked with corporal hygiene and with two synonymous: no trace, no germ Discussion underlines the interest of this method for professional representations studies and nosocomial infections strength.
Sorveglianza delle infezioni e delle colonizzazioni nosocomiali condotta presso la UTI dell'AOUP "P. Giaccone" di Palermo

Epidemiología de Klebsiella pneumoniae productora de beta-lactamasa de espectro extendido en una unidad de cuidados intensivos: Descripción clínica y…
2020
INTRODUCCIÓN: Klebsiella pneumoniae es uno de los microorganismos más frecuentemente relacionados con infecciones asociadas con la asistencia sanitaria, siendo el principal mecanismo de resistencia a betalactámicos el debido a la producción de betalactamasas. Entre los factores de riesgo asociados a la colonización/infección por enterobacterias BLEE destacan la estancia previa en unidades de cuidados intensivos, el estado de portador, la exposición a antibióticos, la necesidad de ventilación mecánica y cirugía previa. La asociación de la multirresistencia con el aumento de la mortalidad, estancia, coste y limitación de opciones terapéuticas, explican la importancia clínica del control de es…
Genotyping and Antifungal Susceptibility of Dipodascus capitatus Isolated in a Neonatal Intensive Care Unit of a Sicilian Hospital
2017
In August 2015, Dipodascus capitatus was isolated from two patients admitted to the neonatal intensive care unit. Nosocomial acquisition of the fungus was suspected and epidemiological studies were undertaken. The patients were simultaneously hospitalized, and the comparison of the two isolates by two independent molecular typing methods have confirmed clonal dissemination of a single strain of D. capitatus. Antimicrobial susceptibility testing was useful for identifying the appropriated antifungal therapy in micafungin. To our knowledge these are the first described cases of neonatal D. capitatus infection and also the first report of successful treatment by micafungin.
Is there a widespread clone of Serratia marcescens producing outbreaks worldwide?
2021
[Background]: Serratia marcescens frequently causes outbreaks in healthcare settings. There are few studies using high-throughput sequencing (HTS) that analyse S. marcescens outbreaks. We present the analysis of two outbreaks in neonatal intensive care units (NICUs) in hospitals from the Comunitat Valenciana (CV, Spain) and the impact of using different reference genomes.
Consensus document on controversial issues for the treatment of hospital-associated pneumonia
2010
Background: Hospital-associated pneumonia (HAP) remains an important cause of morbidity and mortality despite advances in antimicrobial therapy. Many aspects of the treatment of HAP caused by multi-resistant Gram-positive microorganisms have been extensively studied, but controversial issues remain. Controversial issues: The aim of this GISIG (Gruppo Italiano di Studio sulle Infezioni Gravi) working group – a panel of multidisciplinary experts – was to define recommendations for some controversial issues using an evidence-based and analytical approach. The controversial issues were: (1) Is combination antibiotic therapy or monotherapy more effective in the treatment of HAP? (2) What role do…
