Evaluation of a peracetic-acid-based sink drain disinfectant on the intensive care unit of a tertiary care centre in Belgium.

Background: Sink drains in hospitals are notorious reservoirs of bacteria, hosting both planktonic micro-organisms and biofilms within the siphon. Disinfectants based on peracetic acid are both non-corrosive and effective in eliminating biofilm and planktonic micro-organisms, presenting a potential solution for decontaminating sink drains.

Aim: To examine the effectiveness of Clinell Drain Disinfectant, a peracetic-acid-based disinfectant, in the intensive care unit (ICU) of UZ Brussel.

Acetic acid as a decontamination method for ICU sink drains colonized by carbapenemase-producing Enterobacteriaceae and its effect on CPE infections.

Background: Carbapenemase-producing Enterobacteriaceae (CPE) are emerging pathogens representing a major concern for public health. In Belgium, the OXA-48 carbapenemase resistance gene is identified most frequently. Sink drains in intensive care units (ICUs) are known to be colonized by Gram-negative bacilli.

Prevalence and antimicrobial susceptibility of methicillin-resistant Staphylococcus aureus among pigs in Belgium.

The prevalence, distribution, and antimicrobial susceptibility of methicillin-resistant Staphylococcus aureus (MRSA) in Belgian pig farms has been investigated. To that end, nasal samples were collected from 1,500 pigs on 50 farms randomly selected over Belgium. Both closed (breeding or farrow-to-finish) and open (fattening) farms were included.

The 2007 Belgian national prevalence survey for hospital-acquired infections.

Despite ongoing targeted surveillance efforts, no overall in-hospital prevalence data for hospital-acquired infections (HAIs) have been published for Belgium. Sixty-three Belgian acute hospitals participated in a point-prevalence study among either all patients admitted in their institution or 50% of the patients in each ward. HAIs were registered bed-site at a single day per ward during the period October-November 2007.

Contribution of two molecular assays as compared to selective culture for MRSA screening in a low MRSA prevalence population.

Background: As the prompt detection of methicillin-resistant Staphylococcus aureus (MRSA) carriers upon admission is fundamental in the MRSA prevention strategy of our hospital, the infection control team is eagerly seeking the most sensitive and rapid screening method. The aim of this study was to compare the performance of two molecular techniques with a conventional MRSA-selective culture test (Bio-Rad chromogenic MRSASelect) in order to elucidate the suitability of the assays specifically in an expected low MRSA prevalence population.

Patients And Methods: The anterior nares and throat of 500 patients and visitors attending the emergency department of Sint-Jan General Hospital between May and June 2007 were sampled, and MRSA carriage was determined by selective culture after enrichment and the BD GeneOhm StaphSR and the Cepheid Xpert MRSA assays.

Objectives: The aim of the study was to evaluate the antibiotic resistance in noninvasive clinical isolates of Streptococcus pneumoniae collected in Belgium during winter 2008-2007.

Method: Four hundred and forty eight unduplicated isolates collected by 15 laboratories were tested by microdilution following CLSI.

Results: Insusceptibility rates (I+R) were as follows: penicillin G (PEN) 11.

Methicillin-resistant Staphylococcus aureus ST398 in swine farm personnel, Belgium.

We assessed methicillin-resistant Staphylococcus aureus (MRSA) in persons on 49 swine farms in Belgium. Surveys showed that 48 (37.8%) persons carried MRSA ST398 and 1 (0.

Achievements of the Belgian Antibiotic Policy Coordination Committee (BAPCOC).

A Belgian Antibiotic Policy Coordination Committee (BAPCOC) was officially established in 1999 by Royal Decree. The overall objective of BAPCOC is to promote judicious use of antibiotics in humans and animals and to promote infection control and hospital hygiene, with the overall aim to reduce antibiotic resistance. BAPCOC fostered strong and interdisciplinary public health, scientific and political leadership, which led to many evidence-based interventions such as multimedia campaigns to promote the prudent use of antibiotics in the community, national campaigns to promote hand hygiene in hospitals, publication of clinical practice guidelines, staffing and technical support for establishment of antibiotic management teams in all Belgian hospitals, surveillance programmes on antibiotic use and resistance in humans and animals and the promotion of research.

Cost of the meticillin-resistant Staphylococcus aureus search and destroy policy in a Dutch university hospital.

Costs related to a search and destroy policy and treatment for Staphylococcus aureus bacteraemia in the University Hospital Maastricht were calculated for the period 2000 and 2004. The financial cost-benefit break-even point of the search and destroy policy was determined by modelling. On average 22,412 patients were admitted per year for an average of 8.

Complicated community-acquired soft tissue infection by MRSA from porcine origin.

Methicillin-resistant Staphylococcus aureus (MRSA) is a rare cause of community acquired soft tissue infection in Europe. We report a case of severe soft tissue infection caused by a MRSA strain originating from a pig bite.

Dual infection with polyomavirus BK and acyclovir-resistant herpes simplex virus successfully treated with cidofovir in a bone marrow transplant recipient.

A hematopoietic stem cell transplant recipient developed a mucosal herpes simplex virus-1 (HSV-1) infection while under acyclovir (ACV) treatment (HSV was later shown to be resistant to ACV). Concomitantly, the patient presented a hemorrhagic cystitis (HC) due to polyomavirus BK, for which intravenous cidofovir (CDV) was prescribed. The patient benefited from the broad-spectrum anti-DNA virus activity of CDV, and not only the HC resolved without signs of nephrotoxicity but also the HSV-1 lesions disappeared.

Third Belgian multicentre survey of antibiotic susceptibility of anaerobic bacteria.

Objectives: To collect recent data on the susceptibility of anaerobes and to compare them with results from previous studies.

Methods: Four hundred and forty-three anaerobic clinical isolates from various body sites were prospectively collected from October 2003 to February 2005 in nine Belgian hospitals. MICs were determined for nine anti-anaerobic and three recently developed antibiotics.

Surveillance of antibiotic resistance in non invasive clinical isolates of Streptococcus pneumoniae collected in Belgium during winters 2003 and 2004.

A total of 391 and 424 non-invasive isolates of Streptococcus pneumoniae collected by 15 laboratories during the 2003 and 2004 survey were tested for their susceptibility by a microdilution technique following NCCLS recommendations. Insusceptibility rates (IR) in the two surveys (2003/2004) were as follows: penicillin 15.0/14.

The training curriculum in hospital infection control.

Standardised training curricula for infection control nurses (ICNs) and recognition of the specialty exist in many European countries, but infection control physician (ICP) is not a specialty recognised by the UEMS. To gather information on curricula for ICPs, members of the ESCMID Study Group on Nosocomial Infections received a questionnaire. There is discussion about which 'professions' should be included in an infection control team.

Models for the organisation of hospital infection control and prevention programmes.

Hospital infection control is an essential part of infectious disease management and must be firmly structured and professionally organised. Prevention, limitation and eradication of nosocomial infections requires specific expertise not fully provided by clinical microbiologists and/or infectious disease consultants. Therefore, dedicated infection control physicians and nurses are essential.

Environmental investigations and molecular typing of Aspergillus flavus during an outbreak of postoperative infections.

After an outbreak of sternal surgical-site infections (SSSI) with Aspergillus flavus following cardiac surgery, a mycological survey of air and surfaces (41 and 149 samples, respectively) was performed throughout the surgical ward (SW) and in other areas of the hospital. Results showed massive contamination by A. flavus: more than 100 cfu per contact plate were frequently observed in some areas of the SW.

Evaluation of a disk diffusion method with cefoxitin (30 microg) for detection of methicillin-resistant Staphylococcus aureus.

The emergence of heterogeneous populations of methicillin-resistant Staphylococcus aureus (MRSA) causes major problems in routine screening for MRSA. In heterogeneous MRSA populations, a proportion of bacterial cells show low-level resistance to oxacillin, with minimal inhibitory concentrations (MICs) of oxacillin ranging between 1 and 100 mg/l, while in homogeneous MRSA populations, the MIC of oxacillin for all cells is >100 mg/l. Routine oxacillin disk diffusion tests often fail to detect heterogeneous MRSA populations.

Tuberculosis of the skull: a case report.

Tuberculosis of the skull is rare. We describe a case of skull tuberculosis in a Somali fugitive. The patient presented with a history of a painful mass at the vertex of the skull.

Surveillance of antibiotic resistance in clinical isolates of Streptococcus pneumoniae collected in Belgium during winter 2000-2001.

A total of 314 isolates of Streptococcus pneumoniae collected by 10 different laboratories were tested for their susceptibility by using a microdilution technique following NCCLS recommendations. The following antibiotics were included: penicillin, ampicillin, amoxicillin, amoxicillin/clavulanate, cefaclor, cefuroxime, cefotaxime, imipenem, ciprofloxacin, gemifloxacin, levofloxacin, erythromycin, clarithromycin, azithromycin, miocamycin, clindamycin and tetracycline. The insusceptibility rate (IR) to penicillin was 21.

Primary meningococcal arthritis of the hip in an immunocompetent adolescent.

The clinical spectrum of meningococcal infection ranges from asymptomatic carriage to fulminant sepsis, with meningitis and septicemia being well-recognized clinical presentations. Meningococcal arthritis as a complication of Neisseria meningitidis infection occurs in about 2-10% of cases, whereas primary meningococcal arthritis (PMA) is a relatively rare phenomenon, even in children. We report here a case of meningococcal infection in an immunocompetent adolescent suffering from acute pain of the right hip as the only symptom upon presentation at the hospital.

Diagnosis and treatment of Aspergillus flavus sternal wound infections after cardiac surgery.

We report the clinical data for 9 patients affected during an outbreak of Aspergillus flavus sternal wound infections after cardiac surgery. In 7 patients, the infection had a locally invasive character, with 3 of these patients having multiple relapses; 2 patients had fulminant mediastinitis and died. Most patients received combined surgical and medical treatment.

Differentiation and identification of Enterococcus durans, E. hirae and E. villorum.

Aims: To compare different tests in the identification of Enterococcus durans, E. hirae and E. villorum strains.

Recurrent bacteremia by Chryseobacterium indologenes in an oncology patient with a totally implanted intravascular device.

Chryseobacterium indologenes was isolated from the blood cultures of an oncological patient with a totally implantable device. Because a catheter-related infection was suspected, the Port-A-Cath was removed after a 10-day course of piperacillin-tazobactam. Differences in susceptibility may exist if either the criteria for either Pseudomonas or Enterobacteriaceae are used.

In vitro study on the antimicrobial activity of various antibiotics against clinical isolates of Streptococcus pneumoniae from Belgium collected during winter 1998-1999.

A total of 205 isolates of Streptococcus pneumoniae obtained from 10 different centres were included in this study. The susceptibilities to penicillin, ampicillin, amoxicillin, amoxicillin/clavulanic acid, cefaclor, cefuroxime, cefotaxime, imipenem, ciprofloxacin, gemifloxacin, grepafloxacin, levofloxacin, trovafloxacin, erythromycin, clarithromycin, miocamycin, clindamycin and tetracycline were determined by a microdilution technique following NCCLS recommendations. Decreased susceptibility to penicillin was 16.

National guidelines for the judicious use of glycopeptides in Belgium.

Objective: The 'HICPAC guidelines', published in the USA in 1995 stressed the crucial role of restrictive usage of glycopeptides in the strategy to limit the emergence and spread of resistant enterococci. Because controversy still remains in Belgium on the necessity and feasability of restricting glycopeptide usage, the infectious diseases advisory board (IDAB) developed a consensus statement on the judicious use of glycopeptides in Belgium.

Methods: The literature on the indications for glycopeptide treatment was reviewed, categorized and discussed by a working party of the IDAB.
