BACKGROUND Colistin resistance is of concern since it is increasingly needed to treat infections caused by bacteria resistant to all other antibiotics and has been associated with poorer outcomes. Longitudinal data from in vivo series are sparse. METHODS Under a quality-improvement directive to intensify infection-control measures, extremely(More)
The increasing incidence of carbapenem nonsusceptibility among clinically important species is of global concern. Identification of the molecular mechanisms underlying carbapenem nonsusceptibility is critical for epidemiological investigations. In this report, we describe a real-time PCR-based assay capable of simultaneously detecting blaKPC and blaNDM, two(More)
Within the paradigm of clinical infectious disease research, Acinetobacter baumannii, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa represent the four most clinically relevant, and hence most extensively studied bacteria. Current culture-based methods for identifying these organisms are slow and cumbersome, and there is increasing need(More)
A carbapenem-resistant Acinetobacter baumannii strain was isolated from the peritoneal fluid of a patient with complicated intra-abdominal infection and evaluated at the Multidrug-resistant Organism Repository and Surveillance Network by whole-genome sequencing and real-time PCR. The isolate was sequence type 25 and susceptible to colistin and minocycline,(More)
A carbapenem-resistant Alcaligenes faecalis strain was isolated from a surveillance swab of a service member injured in Afghanistan. The isolate was positive for bla(NDM) by real-time PCR. Species identification was reevaluated on three identification systems but was inconclusive. Genome sequencing indicated that the closest relative was Acinetobacter(More)
Venus, unlike Earth, is an extremely dry planet although both began with similar masses, distances from the Sun, and presumably water inventories. The high deuterium-to-hydrogen ratio in the venusian atmosphere relative to Earth's also indicates that the atmosphere has undergone significantly different evolution over the age of the Solar System. Present-day(More)
We describe a real-time PCR-based assay capable of simultaneously detecting femA (Staphylococcus aureus-specific), mecA (methicillin resistance), qacA/B (chlorhexidine tolerance), and mupA (high-level mupirocin resistance) from bacterial cells in less than 90 minutes. The assay was validated with 1968 clinical MRSA submitted to a surveillance network.
