Spanish Multicenter Study of the Epidemiology and Mechanisms of Amoxicillin-Clavulanate Resistance in Escherichia coli [Article]
(American Society for Microbiology, 2012-07)
We conducted a prospective multicenter study in Spain to characterize the mechanisms of resistance to amoxicillin-clavu-lanate (AMC) in Escherichia coli. Up to 44 AMC-resistant E. coli isolates (MIC>32/16 g/ml) were collected ...
Clinical features and epidemiology of acinetobacter baumanni colonization and infection in spanish hospitals [Article]
(SLACK, 2004-10)
OBJECTIVE: To investigate the clinical features and the epidemiology of Acinetobacter baumannii in Spanish hospitals. DESIGN: Prospective multicenter cohort study. SETTING: Twenty-seven general hospitals and one paraplegic ...
Diversity of Escherichia coli Strains Producing Extended-Spectrum B-Lactamases in Spain: Second Nationwide Study [Article]
(American Society for Microbiology, 2010-08)
The prevalence of extended-spectrum -lactamase (ESBL)-producing Escherichia coli (ESBLEC) in Spain increased 8-fold from 2000 to 2006. ESBL type, clonal relationship, antimicrobial susceptibility, and clinical data about ...
Prospective Multicenter Study of the Impact of Carbapenem Resistance on Mortality in Pseudomonas aeruginosa Bloodstream Infections [Article]
(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 ...
Epidemiology and Clinical Features of Infections Caused by Extended-Spectrum Beta-Lactamase-Producing Escherichia coli in Nonhospitalized Patients [Article]
(American Society for Microbiology, 2004-03)
Infections due to extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli (ESBLEC) in nonhospitalize patients seem to be emerging in different countries. Their incidence, epidemiology, and clinical impact in the ...
Genetic Variability among ampC Genes from Acinetobacter Genomic Species 3 [Article]
(American Society for Microbiology, 2009-03)
As a part of a nationwide study in Spain, 15 clinical isolates of Acinetobacter genomic species 3 (AG3) were analyzed. The main objective of the study was to characterize the ampC genes from these isolates and to determine ...
Clinical Features of Infections and Colonization by Acinetobacter Genospecies 3 [Article]
(American Society for Microbiology, 2010-12)
Two hundred twenty-one isolates of Acinetobacter baumannii and 15 of Acinetobacter genospecies 3 (AG3) were consecutively collected in a 30-day period during the nationwide project GEIH-Ab2000. Nosocomial acquisition (P = ...
Type 1 Integrons in Epidemiologically Unrelated Acinetobacter baumannii Isolates Collected at Spanish Hospitals [Article]
(American Society for Microbiology, 2004-01)
Antimicrobial Susceptibility and Mechanisms of Resistance to Quinolones and b-Lactams in Acinetobacter Genospecies 3 [Article]
(American Society for Microbiology, 2004-04)
Antimicrobial susceptibility was determined in 15 epidemiologically unrelated clinical isolates of Acinetobacter genospecies 3. Moreover, the mechanisms of resistance to some b-lactam antibiotics may be associated with the ...
Four main virotypes among extended-spectrum-β-lactamase-producing isolates of Escherichia coli O25b:H4-B2-ST131: bacterial, epidemiological, and clinical characteristics [Article]
(American Society for Microbiology, 2013-10)
A total of 1,021 extended-spectrum- -lactamase-producing Escherichia coli (ESBLEC) isolates obtained in 2006 during a Spanish national survey conducted in 44 hospitals were analyzed for the presence of the O25b:H4-B2-ST131 ...
