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)
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)
BACKGROUND War-trauma, especially due to blast injury, can be associated with long bone fracture. Immediate external fixation of fractures, followed by internal fixation when the patient is medically stabilized (damage control orthopedics [DCO]), is the U.S. Army policy for war-related fractures. Data on infectious outcomes when DCO is used for war-trauma(More)
OBJECTIVE To evaluate the impact of fluconazole prophylaxis on the incidence of fungal infections and on mortality among critically ill surgical patients. DESIGN Meta-analysis of randomized, placebo-controlled trials of fluconazole prophylaxis. PATIENTS Subjects participating in the clinical trials in this area. MEASUREMENTS AND MAIN RESULTS We(More)
INTRODUCTION Trauma is a major cause of morbidity and mortality worldwide. Of patients arriving to trauma centers, patients requiring massive transfusion (MT, >or=10 units in 24 hours) are a small patient subset but are at the highest risk of mortality. Transfusion of appropriate ratios of blood products to such patients has recently been an area of(More)
BACKGROUND Novel influenza viruses continue to pose a potential pandemic threat worldwide. In recent years, plants have been used to produce recombinant proteins, including subunit vaccines. A subunit influenza vaccine, HAC1, based on recombinant hemagglutinin from the 2009 pandemic A/California/04/2009 (H1N1) strain of influenza virus, has been(More)
We describe the clinical, microbiologic, and molecular features of the first series of qacA/B-containing strains of methicillin-resistant Staphylococcus aureus from infected US patients. All qac-carrying strains were clonally diverse, and qacA strains exhibited increased tolerance to chlorhexidine as measured by minimum inhibitory concentrations, minimum(More)
Mucormycosis is an aggressive and potentially devastating fungal infection which typically manifests in pulmonary, rhinocerebral, or disseminated forms in patients with hematologic malignancy. Mucormycosis confined to the periodontium is uncommon, and to our knowledge only 6 cases have been reported in the English-language literature. This case report(More)
BACKGROUND Severe Acinetobacter baumannii infections in immunocompetent patients are uncommon, and the virulence mechanisms of this organism are not fully understood. METHODS Following an outbreak of fatal A. baumannii infections in a cohort of relatively immunocompetent patients (low comorbidity and illness severity scores), isolates were investigated(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.
