The presence of serum bactericidal antibodies is a proven correlate of protection against systemic infection with the important human pathogen Neisseria meningitidis. We have identified three serogroup C N. meningitidis (MenC) isolates recovered from patients with invasive meningococcal disease that resist killing by bactericidal antibodies induced by the(More)
OBJECTIVES To assess the ciprofloxacin resistance of Neisseria meningitidis isolated from 1999 through 2006 in Spain, susceptibility testing was conducted on 5300 isolates. METHODS Ten isolates showed MICs of ciprofloxacin ranging between 0.06 and 0.25 mg/L, and they were characterized by analysis for mutations within the quinolone resistance determining(More)
The effect of conventional i.v. anaesthetic agents on atrial fibrillation (AF) dynamics has not been fully addressed. We aim to evaluate whether the most frequently used intravenous anaesthetic agent, propofol, modifies AF organization parameters. Multiple and simultaneous intraatrial bipolar recordings from 27 patients in AF were analyzed before and after(More)
The mechanisms responsible for the maintenance of atrial fibrillation (AF) are not completely understood yet. It has been demonstrated that AF can be modulated by several cardiac diseases, the autonomic nervous system and even drugs with purportedly no antiarrhythmic properties. We evaluated the effects of a widely used anaesthetic agent (propofol) in the(More)
BACKGROUND A novel meningococcal multicomponent vaccine, 4CMenB (Bexsero®), has been approved in Europe, Canada, Australia and US. The potential impact of 4CMenB on strain coverage is being estimated by using Meningococcal Antigen Typing System (MATS), an ELISA assay which measures vaccine antigen expression and diversity in each strain. Here we show the(More)
BACKGROUND Meningococcal C (MenC) conjugate vaccines have controlled invasive diseases associated with this serogroup in countries where they are included in National Immunization Programs and also in an extensive catch-up program involving subjects up to 20 years of age. Catch-up was important, not only because it prevented disease in adolescents and young(More)
