β-Lactam/β-Lactam Inhibitor Combinations for the Treatment of Bacteremia Due to Extended-Spectrum β-Lactamase-Producing Escherichia coli: A Post Hoc Analysis of Prospective Cohorts
(Oxford University Press, 2012)
Background. Extended-spectrum ß-lactamase–producing Escherichia coli (ESBL-EC) is an important cause of invasive infections. Alternatives to carbapenems—considered the drugs of choice—are needed because of the emergence ...

Is reduced vancomycin susceptibility a factor associated with poor prognosis in MSSA bacteraemia?
(Oxford University Press, 2015)
Objectives: The known data about the influence of vancomycin MIC on Staphylococcus aureus bacteraemia are contradictory. Our objective was to study the possible impact of vancomycin MIC ≥1.5 mg/L on short- and medium-term ...

Prospective Multicenter Study of the Impact of Carbapenem Resistance on Mortality in Pseudomonas aeruginosa Bloodstream Infections
(American Society for Microbiology, 2012)
The impact of antimicrobial resistance on clinical outcomes is the subject of ongoing investigations, although uncertainty remains about its contribution to mortality. We investigated the impact of carbapenem resistance ...

Prevalence of and Risk Factors for Biliary Carriage of Bacteria Showing Worrisome and Unexpected Resistance Traits
(American Society for Microbiology, 2013-02)
Data on biliary carriage of bacteria and, specifically, of bacteria with worrisome and unexpected resistance traits (URB) are lacking. A prospective study (April 2010 to December 2011) was performed that included all ...

Prevalence and transmission dynamics of Escherichia coli ST131 among contacts of infected community and hospitalized patients
(Elsevier, 2018)
Objectives: The Escherichia coli O25b-associated ST131 clonal group was recently found to be prevalent in our area as a cause of community-acquired urinary tract infections. We evaluated the transmission dynamics and ...

A multinational, preregistered cohort study of β-lactam/β-lactamase inhibitor combinations for treatment of bloodstream infections due to extended-spectrum-β-lactamase-producing enterobacteriaceae
(American Society for Microbiology, 2016-07-01)
The spread of extended-spectrum-β-lactamase (ESBL)-producing Enterobacteriaceae (ESBL-E) is leading to increased carbapenem consumption. Alternatives to carbapenems need to be investigated. We investigated whether ...

Virulence Profiles of Bacteremic Extended-Spectrum β-Lactamase-Producing Escherichia coli: Association with Epidemiological and Clinical Features
(Public Library of Science, 2012)
There is scarce data about the importance of phylogroups and virulence factors (VF) in bloodstream infections (BSI) caused by extended-spectrum β-lactamase-producing Escherichia coli (ESBLEC). A prospective multicenter ...

Epidemiology and clinical features of community-acquired, healthcare-associated and nosocomial bloodstream infections in tertiary-care and community hospitals
(Elsevier, 2010-09)
Classification of bloodstream infections (BSIs) as community-acquired (CA), healthcare-associated (HCA) and hospital-acquired (HA) has been proposed. The epidemiology and clinical features of BSI according to that ...

Impact of Inadequate Empirical Therapy on the Mortality of Patients with Bloodstream Infections: a Propensity Score-Based Analysis
(American Society for Microbiology, 2012)
The impact of the adequacy of empirical therapy on outcome for patients with bloodstream infections (BSI) is key for determin- ing whether adequate empirical coverage should be prioritized over other, more conservative ...

Epidemiologic and Clinical Impact of Acinetobacter baumannii Colonization and Infection: A Reappraisal
(Lippincott Williams & Wilkins, 2014)
Acinetobacter baumannii is one of the most important antibiotic-resistant nosocomial bacteria. We investigated changes in the clinical and molecular epidemiology of A. baumannii over a 10-year period. We compared the data ...
