Jesús Oteo, María Teresa Pérez-Vázquez, José Guevara Campos
Current opinion in infectious diseases
2010

PURPOSE OF REVIEW This review discusses the recent findings (July 2008-January 2010) on extended-spectrum [beta]-lactamase (ESBL)-producing Escherichia coli, mainly focussed on the epidemiology and… (More)

Spread of Escherichia coli strains with high-level cefotaxime and ceftazidime resistance between the community, long-term care facilities, and hospital institutions.

Jesús Oteo, Carmen Navarro, +10 authors José Guevara Campos
Journal of clinical microbiology
2006

A total of 151 Escherichia coli strains resistant to cefotaxime and ceftazidime were isolated during a prospective surveillance study. These strains were characterized by clinical, microbiological,… (More)

Ampicillin-resistant non-beta-lactamase-producing Haemophilus influenzae in Spain: recent emergence of clonal isolates with increased resistance to cefotaxime and cefixime.

Antimicrobial agents and chemotherapy
2007

The sequence of the ftsI gene encoding the transpeptidase domain of penicillin-binding protein 3 (PBP 3) was determined for 354 nonconsecutive Haemophilus influenzae isolates from Spain; 17.8% of… (More)

Prospective multicenter study of carbapenemase-producing Enterobacteriaceae from 83 hospitals in Spain reveals high in vitro susceptibility to colistin and meropenem.

Jesús Oteo, Adriana Emitzá Guzmán Ortega, +19 authors José Guevara Campos
Antimicrobial agents and chemotherapy
2015

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 geographic distribution of CPE… (More)

Emergence of OXA-48-producing Klebsiella pneumoniae and the novel carbapenemases OXA-244 and OXA-245 in Spain.

Jesús Oteo, Juan Manuel Sánchez-Terán Hernández, +17 authors José Guevara Campos
The Journal of antimicrobial chemotherapy
2013

OBJECTIVES To describe the molecular and population-level characterization of a selected group of OXA-48-like-producing Klebsiella pneumoniae isolates collected in Spain between January 2011 and May… (More)

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.

Jesús Oteo, Karol Diestra, +10 authors José Guevara Campos
International journal of antimicrobial agents
2009

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 multilocus… (More)

Characterization of plasmids encoding blaESBL and surrounding genes in Spanish clinical isolates of Escherichia coli and Klebsiella pneumoniae.

Karol Diestra, Carlos Juan, +9 authors Ferrán Navarro
The Journal of antimicrobial chemotherapy
2009

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. … (More)

Emergence of CTX-M-15-producing Klebsiella pneumoniae of multilocus sequence types 1, 11, 14, 17, 20, 35 and 36 as pathogens and colonizers in newborns and adults.

Jesús Oteo, O. Cuevas, +12 authors José Guevara Campos
The Journal of antimicrobial chemotherapy
2009

OBJECTIVES To characterize the population structure and resistance mechanisms of Klebsiella pneumoniae isolates that are highly resistant to third-generation cephalosporins, collected from five… (More)

Spanish multicenter study of the epidemiology and mechanisms of amoxicillin-clavulanate resistance in Escherichia coli.

Adriana Emitzá Guzmán Ortega, Jesús Oteo, +16 authors José Guevara Campos
Antimicrobial agents and chemotherapy
2012

We conducted a prospective multicenter study in Spain to characterize the mechanisms of resistance to amoxicillin-clavulanate (AMC) in Escherichia coli. Up to 44 AMC-resistant E. coli isolates (MIC ≥… (More)

Spread of invasive Spanish Staphylococcus aureus spa-type t067 associated with a high prevalence of the aminoglycoside-modifying enzyme gene ant(4')-Ia and the efflux pump genes msrA/msrB.

María Teresa Pérez-Vázquez, Ana Vindel, +6 authors José Guevara Campos
The Journal of antimicrobial chemotherapy
