Molecular Epidemiology of Mycobacterium tuberculosis Strains Isolated during a 3-Year Period (1993 to 1995) in Seville, Spain
(American Society for Microbiology, 1997)
The genetic polymorphism of Mycobacterium tuberculosis strains isolated in Seville, Spain, was studied by using computer-assisted analysis of the IS6110 fingerprint in order to determine the current situation and to evaluate ...

Rice and bean AHL-mimic quorum-sensing signals specifically interfere with the capacity to form biofilms by plant-associated bacteria
(2013)
Many bacteria regulate their gene expression in response to changes in their population density in a process called quorum sensing (QS), which involves communication between cells mediated by small diffusible signal molecules ...

Hanks-Type Serine/Threonine Protein Kinases and Phosphatases in Bacteria: Roles in Signaling and Adaptation to Various Environments
(MDPI, 2018)
Reversible phosphorylation is a key mechanism that regulates many cellular processes in prokaryotes and eukaryotes. In prokaryotes, signal transduction includes two-component signaling systems, which involve a membrane ...

Direct Detection of Rifampin- and Isoniazid-Resistant Mycobacterium tuberculosis in Auramine-Rhodamine-Positive Sputum Specimens by Real-Time PCR
(American Society for Microbiology, 2004)
Our objective was to evaluate the feasibility of a molecular assay based on a real-time PCR technique, carried out with a LightCycler instrument (Roche Biochemicals), to identify Mycobacterium tuberculosis bacilli and to ...

Effect of Statin Therapy in the Outcome of Bloodstream Infections Due to Staphylococcus aureus: A Prospective Cohort Study
(Public Library of Science (PLoS), 2013)
Introduction: Statins have pleiotropic effects that could influence the prevention and outcome of some infectious diseases. There is no information about their specific effect on Staphylococcus aureus bacteremia ...

The P. aeruginosa effector Tse5 forms membrane pores disrupting the membrane potential of intoxicated bacteria
(Nature Publishing Group, 2022)
The type VI secretion system (T6SS) of Pseudomonas aeruginosa injects effector proteins into neighbouring competitors and host cells, providing a fitness advantage that allows this opportunistic nosocomial pathogen to ...

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 ...

OnfD, an AraC-Type Transcriptional Regulator Encoded by Rhizobium tropici CIAT 899 and Involved in Nod Factor Synthesis and Symbiosis
(American Society for Microbiology, 2020)
Rhizobium tropici CIAT 899 is a broad-host-range rhizobial strain that establishes symbiotic interactions with legumes and tolerates different environmental stresses such as heat, acidity, or salinity. This rhizobial strain ...

Genetic and biochemical study of threonine-overproducing mutants of Saccharomyces cerevisiae
(1982)
Three threonine-overproducing mutants were obtained as prototrophic revertants of a hom3 mutant strain of Saccharomyces cerevisiae. The gene HOM3 codes for aspartokinase (aspartate kinase; EC 2.7.2.4), the first enzyme of ...

Estudio de la respuesta clínica al tratamiento antirretroviral en pacientes infectados por subtipos NO-B de VIH-1 mediante la secuenciación de la proteasa retrotranscriptasa e integras: estudio genotípico del T.
(2014-10-01)
En este trabajo se han detallado los datos epidemiológicos de la infección VIH-1 en Andalucía occidental, prestando especial atención a las infecciones por subtipos no- B. Para ello, se ha realizado un análisis de polimorfismos ...
