The physical capacity of negative pressure wound therapy (NPWT) dressing on the bacterial growth in an in vitro wound model was investigated. Standardised wounds were contaminated with a clinical Staphylococcus aureus strain and incubated at 35 degrees C for 6 hours. Four wounds were treated with continuous negative pressure (125 mmHg) and four controls(More)
BACKGROUND The aim of this study was to investigate the decontamination capacity of 4 different types of cleaning cloths (microfiber cleaning cloth, cotton cloth, sponge cloth, and disposable paper towels) commonly used in hospital in their ability to reduce microbial loads from a surface used dry or wet in new condition. All of the cloths except disposable(More)
BACKGROUND Aspergillus spp are ubiquitous spore-forming fungi. Construction work, renovation, demolition, or excavation activities within a hospital or in surrounding areas increase the risk for aspergillus infection in susceptible patients and are the main cause of nosocomial aspergillus outbreaks. METHODS We investigated the efficacy of infection(More)
BACKGROUND Bacteremias caused by Staphylococcus aureus and Escherichia coli are among the most common bloodstream infections (BSIs) in adults. The aim of the study was to investigate risk factors for infection and clinical outcomes of bacteremias caused by S aureus or E coli. METHODS We conducted a 1-year matched prospective cohort study including 150(More)
BACKGROUND The outcome of patients with bacteraemia is influenced by the initial selection of adequate antimicrobial therapy. The objective of our study was to clarify the influence of different crude data correction methods on a) microbial spectrum and ranking of pathogens, and b) cumulative antimicrobial susceptibility pattern of blood culture isolates(More)
BACKGROUND This study investigated the influence of the size of unidirectional ceiling distribution systems on counts of viable microorganisms recovered at defined sites in operating room (ORs) and on instrument tables during orthopedic surgery. METHODS We compared bacterial sedimentation during 80 orthopedic surgeries. A total of 19 surgeries were(More)
Candida parapsilosis has become a significant cause of invasive fungal infections in seriously ill patients. Nosocomial outbreaks through direct and indirect contact have been described. The aim of this study was the molecular characterization of what appeared to be an ongoing C. parapsilosis outbreak at the cardiothoracic intensive care unit of the(More)
BACKGROUND The aim of this study was to characterise the epidemiology of P. aeruginosa isolated from cystic fibrosis (CF) patients at the Vienna General Hospital (VGH) by molecular genetic fingerprinting in order to understand transmission ways and to evaluate the established infection control protocols. METHODS The outpatient clinic for CF patients at(More)
The purpose of this study was to investigate methicillin-resistant Staphylococcus aureus (MRSA) isolates with antibiotic resistance restricted to beta-lactam antibiotics and variable resistance to fusidic acid for the presence of Panton-Valentine leukocidin (PVL) genes. Our data show that the selected resistance pattern is found rarely among MRSA isolates(More)
Issues over the correct cleaning and disinfection of reusable medical devices are of great concern for local infection control teams. We investigated the heat resistance of two important micro-organisms implicated in nosocomial infections, Enterococcus spp. and spores of Bacillus subtilis (a surrogate for Clostridium difficile). Disinfection with moist(More)
