BACKGROUND Risk factors for Nocardia infection in organ transplant recipients have not been formally assessed in the current era of transplantation. METHODS We performed a matched case-control study (1:2 ratio) between January 1995 and December 2005. Control subjects were matched for transplant type and timing. Univariate matched odds ratios were(More)
Developing nations have many challenges to the growth of emergency medical systems. This development in Afghanistan is also complicated by many factors that plague post-conflict countries including an unstable political system, poor economy, poor baseline health indices, and ongoing violence. Progress has been made in Afghanistan with the implementation of(More)
BACKGROUND With an increase in the use of colistin methansulfonate (CMS) to treat carbapenem-resistant Acinetobacter baumannii infections, colistin resistance is emerging. METHODS Patients with infection or colonization due to colistin-resistant A. baumannii were identified at a hospital system in Pennsylvania. Clinical data were collected from electronic(More)
Infections due to Escherichia coli producing extended-spectrum beta-lactamase (ESBL) or CMY-type beta-lactamase (CMY) are increasingly observed in non-hospitalized patients. The origin of these organisms is uncertain, but retail meat contaminated with E. coli may be a source. In the present study, clinical information and strains collected from patients(More)
Enterobacter cloacae is a major nosocomial pathogen that causes serious infections, including bloodstream infections (BSIs). The clinical significance of extended-spectrum β-lactamase (ESBL) production in E. cloacae is not well established. A multicentre, retrospective, cohort study was conducted to identify clinical characteristics of patients with E.(More)
The dematiaceous mold Ochroconis gallopava is increasingly recognized as a human pathogen. Infection is almost always associated with immunosuppression. We describe a case with a unique presentation in a kidney transplant recipient and retrospectively review all 10 cases of O. gallopava at our institution over 18 yr, all in organ transplant recipients.(More)
Klebsiella pneumoniae producing Klebsiella pneumoniae carbapenemase (KPC) has been associated with serious infections and high mortality. The optimal antimicrobial therapy for infection due to KPC-producing K. pneumoniae is not well established. We conducted a retrospective cohort study to evaluate the clinical outcome of patients with bacteremia caused by(More)
AIM Transplant recipients are at risk for hospital-acquired infections (HAIs), including those caused by Pseudomonas aeruginosa. Of all HAIs, bloodstream infection (BSI) remains one of the most life-threatening. METHODS Over a 10-year period, we studied 503 patients, including 149 transplant recipients, with pseudomonal BSI from the University of(More)
BACKGROUND Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae has become endemic in many US hospitals. On the other hand, KPC-producing Escherichia coli remains rare. METHODS We studied infection or colonization due to KPC-producing E. coli identified at our hospital between September 2008 and February 2011. A case-control study was(More)
