The trypanosome zinc finger protein ZC3H11 binds to AU-rich elements in mRNAs. It is essential for survival of the mammalian-infective bloodstream form, where it stabilizes several mRNAs including some encoding chaperones, and is also required for stabilization of chaperone mRNAs during the heat-shock response in the vector-infective procyclic form. When ZC3H11 was artificially 'tethered' to a ...

BACKGROUND To determine if the catheter lock taurolidine can reduce the number of catheter-related bloodstream infections (CRBSI) in pediatric cancer patients with tunneled central venous catheters (CVC). PROCEDURE During a study period of 34 months, 129 newly placed tunneled CVCs in 112 patients were randomly assigned to standard lock with heparin solution or experimental lock with a tauroli...

p67 is a lysosomal type I membrane glycoprotein of Trypanosoma brucei. In procyclic stage cells p67 trafficks to the lysosome without modification, but in the bloodstream stage Golgi processing adds poly-N-acetyllactosamine to N-glycans. In both stages proteolytic fragmentation occurs in the lysosome, but turnover is approximately nine times faster in bloodstream cells. Trafficking of wildtype ...

OBJECTIVES Tigecycline has shown in vitro activity against Acinetobacter baumannii. Yet, published clinical experience with tigecycline use outside clinical trials is lacking. We describe, for the first time, bloodstream infection caused by tigecycline-non-susceptible A. baumannii occurring in patients receiving tigecycline for other indications. The possible mechanisms of resistance and pharma...

The use of extracorporeal membrane oxygenation (ECMO) for adult patients has increased in recent years. A retrospective cohort study of adult patients undergoing ECMO was performed between 19 February 1985 and 10 October 1995 to evaluate nosocomial infections. Seventy-one evaluable patients underwent ECMO for a total of 799 days. Forty-six infections were identified in 32 (45%) of 71 patients. ...

BACKGROUND Infections occurring among outpatients having recent contact with the health care system have been termed health care-associated infections. The objective of this study was to analyze the impact of health care-associated status on effectiveness of initial therapy in hospitalized patients with bloodstream infections. METHODS Prospective cohort study of adults with bloodstream infect...

OBJECTIVE Major catheter-related infection includes catheter-related bloodstream infections and clinical sepsis without bloodstream infection resolving after catheter removal with a positive quantitative tip culture. Insertion site dressings are a major mean to reduce catheter infections by the extraluminal route. However, the importance of dressing disruptions in the occurrence of major cathet...

BACKGROUND Recent studies have suggested that community-associated methicillin-resistant Staphylococcus aureus (MRSA) infection is encroaching on health care settings. We describe the epidemiology of hospital-onset community-associated MRSA bloodstream infections using phenotypic and genotypic analysis. METHODS Using an update of an established rule derived from antibiotic susceptibilities, w...

African trypanosomes are sustained in the bloodstream of their mammalian hosts by their extreme capacity for antigenic variation. However, for life cycle progression, trypanosomes also must generate transmission stages called stumpy forms that are pre-adapted to survive when taken up during the bloodmeal of the disease vector, tsetse flies. These stumpy forms are rather different to the prolife...
