Journal ArticleDOI
Biological Cost of Different Mechanisms of Colistin Resistance and Their Impact on Virulence in Acinetobacter baumannii
Alejandro Beceiro,Antonio Moreno,Nathalie Fernandez,Juan A. Vallejo,Jesús Aranda,Ben Adler,Marina Harper,John D. Boyce,Germán Bou +8 more
TL;DR: While Colistin resistance in A. baumannii confers a clear selective advantage in the presence of colistin treatment, it causes a noticeable cost in terms of overall fitness and virulence, with a more striking reduction associated with LPS loss than with phosphoethanolamine addition.
Journal ArticleDOI
Improved Cardiac Function in Patients With Obstructive Jaundice After Internal Biliary Drainage: Hemodynamic and Hormonal Assessment
Javier Padillo,Jesús Puente,Manuel Gómez,Francisco Javier González de Dios,Antonio Naranjo,Juan A. Vallejo,G Miño,C. Pera,Antonio Sitges-Serra +8 more
TL;DR: Increased plasma levels of natriuretic peptides in patients with obstructiveJaundice may reflect a subclinical myocardial dysfunction correlating with the degree of jaundice, and after internal biliary drainage, there is a measurable improvement of cardiac function.
Journal ArticleDOI
Short communication: A comparative analysis of recombinant chymosins
TL;DR: It is proposed that recombinant goat chymosin represents a serious alternative to recombinant bovine chymOSin for use in the cheesemaking industry.
Journal ArticleDOI
The FhaB/FhaC two-partner secretion system is involved in adhesion of Acinetobacter baumannii AbH12O-A2 strain
Astrid Pérez,María Merino,Soraya Rumbo-Feal,Laura Álvarez-Fraga,Juan A. Vallejo,Alejandro Beceiro,Emily J. Ohneck,Jesús Mateos,Patricia Fernández-Puente,Luis A. Actis,Margarita Poza,Germán Bou +11 more
TL;DR: Scanning electron microscopy and adhesion experiments demonstrated that inactivation of the AbFhaB/FhaC system significantly decreases bacterial attachment to A549 alveolar epithelial cells, and it has been demonstrated that this 2-partner secretion system is involved in fibronectin-mediated adherence of the A. baumannii AbH12O-A2 isolate.
Journal ArticleDOI
Analysis of the role of the LH92_11085 gene of a biofilm hyper-producing Acinetobacter baumannii strain on biofilm formation and attachment to eukaryotic cells.
Laura Álvarez-Fraga,Astrid Pérez,Soraya Rumbo-Feal,María Merino,Juan A. Vallejo,Emily J. Ohneck,Richard E. Edelmann,Alejandro Beceiro,Juan C. Vázquez-Ucha,Jaione Valle,Luis A. Actis,Germán Bou,Margarita Poza +12 more
TL;DR: Scanning electron microscopy and biofilm assays showed that inactivation of LH92_11085 gene significantly reduced bacterial attachment to A549 cells and bio film formation on plastic, respectively, indicating the potential role this LH92-110 85 gene could play in the pathobiology of A baumannii.
