We explored the variation in proportions of methicillin-resistant Staphylococcus aureus (MRSA) between and within countries participating in the European Antimicrobial Resistance Surveillance System and temporal trends in its occurrence. This system collects routine antimicrobial susceptibility tests for S. aureus. We examined data collected from January(More)
For the detection of six groups of anaerobic bacteria in human feces, we designed seven new 16S rRNA-based oligonucleotide probes. This set of probes extends the current set of probes and gives more data on the composition of the human gut flora. Probes were designed for Phascolarctobacterium and relatives (Phasco741), Veillonella (Veil223), Eubacterium(More)
Periodontitis and caries are infectious diseases of the oral cavity in which oral biofilms play a causative role. Moreover, oral biofilms are widely studied as model systems for bacterial adhesion, biofilm development, and biofilm resistance to antibiotics, due to their widespread presence and accessibility. Despite descriptions of initial plaque formation(More)
PURPOSE Although the relevance of cultural factors for antibiotic use has been recognized, few studies exist in Europe. We compared public attitudes, beliefs and knowledge concerning antibiotic use and self-medication between 11 European countries. METHODS In total, 1101 respondents were interviewed on their attitudes towards appropriateness of(More)
BACKGROUND Self-medication with antibiotics occurs among the population in Europe, particularly in southern and eastern countries. We studied the impact of predisposing factors (e.g. attitudes and knowledge concerning antibiotic use and self-medication) and enabling factors (country wealth and healthcare system factors) on self-medication with antibiotics(More)
Based on data collected by the European Antimicrobial Resistance Surveillance Network (EARS-Net) and the former EARSS, the present study describes the trends in antimicrobial susceptibility patterns and occurrence of invasive infections caused by Escherichia coli and Staphylococcus aureus in the period from 2002 to 2009. Antimicrobial susceptibility results(More)
Enterococcus faecalis and Enterococcus faecium are among the leading causes of hospital-acquired infections. Reliable and quick identification of E. faecalis and E. faecium is important for accurate treatment and understanding their role in the pathogenesis of infections. Fluorescent in situ hybridization (FISH) of whole bacterial cells with(More)
Forty-three evaluable patients with hematologic malignancies, mainly acute leukemia, were prospectively randomized to receive a double lumen central venous catheter or a totally implantable venous access system. The mean catheter stay was 166 days (median, 104 days) for the 23 double lumen catheters and 164 days (median, 65 days) for implanted systems. Exit(More)
In Europe, antimicrobial resistance has been monitored since 1998 by the European Antimicrobial Resistance Surveillance System (EARSS). We examined the relationship between penicillin nonsusceptibility of invasive isolates of Streptococcus pneumoniae and antibiotic sales. Information was collected on 1998-99 resistance data for invasive isolates of S.(More)
Two 16S rRNA-targeted probes were developed: one for the Coriobacterium group and the other for the Atopobium cluster (which comprises most of the Coriobacteriaceae species, including the Coriobacterium group). The new probes were based on sequences of three new Coriobacteriaceae strains isolated from human feces and clinical material and sequences from(More)
