Extended-spectrum beta-lactamase-producing Enterobacteriaceae in different environments (humans, food, animal farms and sewage).
OBJECTIVES This study aimed to determine the presence of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae in different environments. METHODS Clinical samples and stool samplesExpand
ESBL- and plasmidic class C beta-lactamase-producing E. coli strains isolated from poultry, pig and rabbit farms.
This study aims to determine the presence of extended-spectrum (ESBL) and plasmidic class C beta-lactamase-producing Enterobacteriaceae in poultry, pig and rabbit farms of Catalonia (Spain). PFGEExpand
Antibiotic Resistance Trends in Enteropathogenic Bacteria Isolated in 1985–1987 and 1995–1998 in Barcelona
ABSTRACT Trends in resistance to antimicrobial agents used for therapy have been evaluated with 3,797 enteropathogenic bacteria,Campylobacter, Salmonella,Shigella, and Yersinia, between 1985–1987 andExpand
Prospective Multicenter Study of Carbapenemase-Producing Enterobacteriaceae from 83 Hospitals in Spain Reveals High In Vitro Susceptibility to Colistin and Meropenem
ABSTRACT The aim of this study was to determine the impact of carbapenemase-producing Enterobacteriaceae (CPE) in Spain in 2013 by describing the prevalence, dissemination, and geographicExpand
Novel Complex sul1-Type Integron in Escherichia coli Carrying blaCTX-M-9
ABSTRACT For the present report, a novel complex class 1 integron, In60, was characterized. Part of this integron includes the blaCTX-M-9 gene and its downstream nucleotide sequence, which shares 81%Expand
Extended-spectrum beta-lactamase-producing Escherichia coli in Spain belong to a large variety of multilocus sequence typing types, including ST10 complex/A, ST23 complex/A and ST131/B2.
In this study, we investigated the population structure of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli in Spain and determined possible associations between specific multilocusExpand
Cloning and Sequence of the Gene Encoding a Novel Cefotaxime-Hydrolyzing β-Lactamase (CTX-M-9) fromEscherichia coli in Spain
ABSTRACT A new CTX-M-type β-lactamase (CTX-M-9) has been cloned from a clinical cefotaxime-resistant Escherichia coli strain. Despite the close identity that exists between the CTX-M-9 and Toho-2Expand
Characterization of plasmids encoding blaESBL and surrounding genes in Spanish clinical isolates of Escherichia coli and Klebsiella pneumoniae.
OBJECTIVES The aim of the study was to characterize plasmids that harbour blaESBL genes and their genetic environment in Escherichia coli and Klebsiella pneumoniae clones circulating in Spain. Expand
Community Transmission of Extended-Spectrum β-Lactamase
To the Editor: The spread of multiresistant gram-negative bacteria in the general population is a problem of paramount importance, but the responsible mechanisms are poorly understood. SeveralExpand
Evidence for convergent evolution of CTX-M-14 ESBL in Escherichia coli and its prevalence.
A total of 2440 Escherichia coli strains isolated in 2003 at the Hospital de la Santa Creu i Sant Pau were evaluated for the presence of extended-spectrum beta-lactamases. Two different nucleotideExpand
