Global dissemination of a multidrug resistant Escherichia coli clone
(National Academy of Sciences, 2014-04)
Escherichia coli sequence type 131 (ST131) is a globally disseminated, multidrug resistant (MDR) clone responsible for a high proportion of urinary tract and bloodstream infections. The rapid emergence and successful ...

Spanish Multicenter Study of the Epidemiology and Mechanisms of Amoxicillin-Clavulanate Resistance in Escherichia coli
(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 ...

Biotic factor does not limit operational pH in packed-bed bioreactor for ferrous iron biooxidation
(Oxford University Press, 2012-12-01)
Ferrous ion biooxidation is a process with many promising industrial applications: mainly regeneration of ferric ion as an oxidizing reagent in bioleaching processes and depuration of acid mine drainage. The flooded packedbed ...

Bacteraemia due to non-ESBL-producing Escherichia coli O25b:H4 sequence type 131: insights into risk factors, clinical features and outcomes
(Elsevier, 2017)
The epidemiology and outcomes of bloodstream infections (BSIs) caused by Escherichia coli ST131 isolates not producing extended-spectrum β-lactamases (ESBLs) are not well defined despite being more prevalent than ESBL-producers. ...

Fosfomycin versus meropenem in bacteraemic urinary tract infections caused by extended-spectrum β-lactamase-producing Escherichia coli (FOREST): study protocol for an investigator-driven randomised controlled trial
(BMJ Publishing Group, 2015)
Introduction Finding therapeutic alternatives to carbapenems in infections caused by extended-spectrum β-lactamase-producing Escherichia coli (ESBL-EC) is imperative. Although fosfomycin was discovered more than 40 years ...

Genomic basis of broad host range and environmental adaptability of Rhizobium tropici CIAT 899 and Rhizobium sp. PRF 81 which are used in inoculants for common bean (Phaseolus vulgaris L.)
(BioMed Central, 2012)
Background Rhizobium tropici CIAT 899 and Rhizobium sp. PRF 81 are α-Proteobacteria that establish nitrogen-fixing symbioses with a range of legume hosts. These strains are broadly used in commercial inoculants for ...

Detección y genotipado del virus del papiloma humano mediante una técnica de PCR a tiempo real: utilidad de la muestra de orina
(2014-12-22)
La infección por el virus del papiloma humano (VPH) es una causa necesaria, aunque, por si sola, insuficiente para el desarrollo del cáncer de cérvix. Normalmente las infecciones por VPH se resuelven espontáneamente, pero ...

In vitro effect photodynamic therapy with differents photosensitizers on cariogenic microorganisms
(BioMed Central, 2015)
Background Antimicrobial photodynamic therapy has been proposed as an alternative to suppress subgingival species. This results from the balance among Streptococcus sanguis, Streptococcus mutans and Candida albicans in ...

In vitro effect of qnrA1, qnrB1, and qnrS1 genes on fluoroquinolone activity against isogenic Escherichia coli isolates with mutations in gyrA and parC
(American Society for Microbiology, 2011-03-01)
This article provides an analysis of the in vitro effect of qnrA1, qnrB1, and qnrS1 genes, combined with quinolone-resistant Ser83Leu substitutions in GyrA and/or Ser80Arg in ParC, on fluoroquinolone (FQ) resistance in ...

Microbial Populations in Ferrous Iron Oxidation Bioreactors
(Universidad Pablo de Olavide de Sevilla, 2016)
Motivación: ferrous iron oxidation can take place in partly controlled biological reactors inoculated with mixed cultures of acidophilic microorganisms. In these bioreactors, liquor pH can affect ...
