In vitro activities of ketolide HMR 3647, macrolides, and clindamycin against coryneform bacteria
(American Society for Microbiology, 1998-12-01)
The in vitro activity of ketolide HMR 3647 against coryneform bacteria isolated from clinical samples was evaluated. Except against Corynebacterium jeikeium and C. urealyticum, HMR 3647 showed high activity against ...
Article
Quality control for β-lactam susceptibility testing with a well-defined collection of Enterobacteriaceae and Pseudomonas aeruginosa strains in Spain
(American Society for Microbiology, 2003)
Eighteen Enterobacteriaceae and Pseudomonas aeruginosa strains, 16 of them with well-defined β-lactam re sistance mechanisms, were sent to 52 Spanish microbiology laboratories. Interpretative categories for 8 extended-spectrum ...
PhD Thesis
Mecanismos de resistencia a Carbapenemas en cepas clínicas de Acinetobacter baumannii
(2001-04-25)
En los últimos años se ha producido un incremento significativo en el número de infecciones nosocomiales causadas por cepas de Acinetobacter baumannii resistentes a carbapenemas. Las opciones terapéuticas en el tratamiento ...
Article
Nationwide study of Escherichia coli and Klebsiella pneumoniae producing extended-spectrum β-lactamases in Spain
(American Society for Microbiology, 2005-05-01)
Clonal dissemination of extended-spectrum -lactamases (ESBL) in 170 Escherichia coli isolates and 70 Klebsiella pneumoniae isolates from a nationwide study of 40 Spanish centers in 2000 was not observed in most centers. ...

Activities of gemifloxacin and five other antimicrobial agents against Listeria monocytogenes and coryneform bacteria isolated from clinical samples
(American Society for Microbiology, 2001-07-31)
The in vitro activities of gemifloxacin, ciprofloxacin, ampicillin, doxycycline, gentamicin, and vancomycin were evaluated against 15 Listeria monocytogenes strains and 205 coryneform bacteria isolated from clinical samples. ...
Article
Comparison of broth microdilution and E-test for susceptibility testing of Neisseria meningitidis
(American Society for Microbiology, 1996)
The susceptibilities of 54 clinical isolates of Neisseria meningitidis to penicillin, cefotaxime, ceftriaxone, cefepime, imipenem, ciprofloxacin, chloramphenicol, and rifampin were determined by the microdilution method ...
Article
Inhibitor-resistant TEM- And OXA-1-producing Escherichia coli isolates resistant to amoxicillin-clavulanate are more clonal and possess lower virulence gene content than susceptible clinical isolates
(American Society for Microbiology, 2014-01-01)
In a previous prospective multicenter study in Spain, we found that OXA-1 and inhibitor-resistant TEM (IRT) β-lactamases constitute the most common plasmid-borne mechanisms of genuine amoxicillin-clavulanate (AMC) resistance ...
Article
Activities of imipenem and cephalosporins against clonally related strains of Escherichia coli hyperproducing chromosomal β-lactamase and showing altered porin profiles
(American Society for Microbiology, 2000-09-06)
Forty clonally related clinical isolates of Escherichia coli from hospitalized patients were resistant to cefoxitin (MICs, >256 μg/ml) and ceftazidime (MICs, 32 to 256 μg/ml) and were intermediate or resistant to cefotaxime ...
Article
Roles of β-Lactamases and Porins in Activities of Carbapenems and Cephalosporins against Klebsiella pneumoniae
(American Society for Microbiology, 1999-07-01)
Two clinical isolates of extended-spectrum β-lactamase (ESBL)- producing Klebsiella pneumoniae were noted to be less susceptible than expected to imipenem. Both were missing outer membrane proteins that serve as channels ...
Article
Mobile genetic elements related to the diffusion of plasmid-mediated AmpC β-lactamases or carbapenemases from enterobacteriaceae: Findings from a multicenter study in Spain
(American Society for Microbiology, 2015-09-01)
We examined the genetic context of 74 acquired ampC genes and 17 carbapenemase genes from 85 of 640 Enterobacteriaceae isolates collected in 2009. Using S1 pulsed-field gel electrophoresis and Southern hybridization, 37 ...
