cations, probably as a consequence of weak antibiotic activity (only ciprofloxacin was active). Identification of both MBL and ESBL in a single P. aeruginosa isolate may represent the ultimate state of multidrug resistance in that species. Furthermore, the emergence of VIM-2 MBL in Turkey, identified for the first time, represents a significant additional(More)
The purpose of this work was to study the adhesion to polystyrene of two Candida parapsilosis strains, grown at 22 and 37 degrees C, in terms of hydrophobicity, surface charge, and interaction free energy. Growth temperature changed the surface properties of microorganisms, yielding a good correlation between thermodynamic predictions and adhesion behavior.
We report a case of actinomycosis with uncommon localizations that was due to Actinomyces meyeri. Although penicillin is the standard treatment for this condition, our patient was treated successfully with imipenem. Actinomyces organisms are important constituents of the normal flora of mucous membranes and are considered opportunistic pathogens; these(More)
The effect of ritonavir and saquinavir, HIV proteinase inhibitors, on the secreted aspartyl proteinase (Sap) activity of Candida parapsilosis was studied. In a proteinase-inducing medium (yeast carbon base-bovine serum albumin), Sap activity in all clinical isolates of C. parapsilosis (n = 20) was observed at 37 degrees C but not at 22 degrees C. The(More)
OBJECTIVES To compare the tigecycline activity profile against Acinetobacter spp. by Etest versus broth microdilution in isolates with high Etest MIC. METHODS Acinetobacter spp. isolates with tigecycline MICs of >or=0.5 mg/L determined by commercially developed Etests strips (January 2006 to July 2007) in five Spanish hospitals were considered. Values(More)
Sir, Linezolid is a last-resort antimicrobial agent in human medicine approved for the control of serious infections caused by Grampositive pathogens. Transferable linezolid resistance is based on the multiresistance gene cfr. Although originally found in staphylococci, this gene has meanwhile been reported in various Grampositive and even Gram-negative(More)
We recently reported the rapid expansion of an HIV-1 subtype F cluster among men who have sex with men (MSM) in the region of Galicia, Northwest Spain. Here we update this outbreak, analyze near full-length genomes, determine phylogenetic relationships, and estimate its origin. For this study, we used sequences of HIV-1 protease-reverse transcriptase and(More)
Coagulase negative staphylococci are a rare cause of native valve endocarditis. Staphylococcus saprophyticus is a coagulase-negative Staphylococcus infrequently reported as a human pathogen, and most of the cases reported are urinary tract infections. We describe a case of native valve endocarditis attributed to this organism. The patient needed valve(More)
INTRODUCTION Coagulase Negative Staphylococci (CNS) have become one of the most common nosocomial pathogens and it has a high mortality rate due to the increased of seriously ill patients survival, long states immunosuppression and presence of foreign bodies, such as catheters, prostheses, pacemakers, etc. In addition, there is a significant increase in(More)
