Diagnostic value of five commercial tests for the rapid diagnosis of Clostridium difficile-associated disease.

We compared five commercial immunoassays (Biostar OIA CdTOX AB, ImmunoCard Toxins A&B - Meridian, Xpect C. difficile toxin A/B -Remel, C. difficile toxin A test- Oxoid, and TOX A/B QUIK CHEK- Techlab) which allow a rapid diagnosis of C.

National survey of molecular epidemiology of Staphylococcus aureus colonization in Belgian cystic fibrosis patients.

Objectives: Epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) is poorly defined in cystic fibrosis (CF) patients, and S. aureus detection may be hampered by the presence of small colony variants (SCVs). We conducted a multicentre survey to determine the prevalence of S.

Antimicrobial susceptibility of clinical isolates of non-jejuni/coli campylobacters and arcobacters from Belgium.

Objectives: To determine the susceptibility of non-jejuni/coli campylobacters and arcobacters isolated from diarrhoeal stool specimens in Belgium.

Methods: The MICs were determined using Etest for six antimicrobial agents including ampicillin, erythromycin, nalidixic acid, ciprofloxacin, gentamicin and tetracycline for the most frequently isolated non-jejuni/coli campylobacter and arcobacter strains in two University Hospital laboratories between 1995 and 2005.

Results: In total, 85 Campylobacter upsaliensis, 20 Campylobacter concisus, 11 Campylobacter fetus, 61 Arcobacter butzleri and 10 Arcobacter cryaerophilus isolates were tested.

Arcobacter species in humans.

During an 8-year study period, Arcobacter butzleri was the fourth most common Campylobacter-like organism isolated from 67,599 stool specimens. Our observations suggest that A. butzleri displays microbiologic and clinical features similar to those of Campylobacter jejuni; however, A.

Evaluation of the ProSpecT Microplate Assay for detection of Campylobacter: a routine laboratory perspective.

Objectives: To evaluate the use of the new enzyme-linked immunosorbent assay, the ProSpecT Campylobacter Microplate Assay (Alexon-Trend, Minneapolis, MN, USA), which allows 2-h detection of both Campylobacter jejuni and Campylobacter coli antigen directly in stool specimens.

Methods: Over 4 months, all stool samples preserved in Cary-Blair medium, or fresh specimens, from non-hospitalized children and HIV-infected patients (adults and children), submitted to our laboratory were evaluated with the ProSpecT Campylobacter Microplate Assay. Results were compared with those obtained by routine culture methods using both a specific medium and a filtration method for the recovery of Campylobacter spp.

[Induced expectoration or endoscopic samples in case of bronchopulmonary infection?].

The aim of this study was to compare induced sputum versus bronchoscopy in a non selected population. An induced sputum and a bronchoscopy with aspiration of secretions and bronchoalveolar lavage (BAL) were proposed to 30 patients with suspected lower respiratory tract infection, including 14 subjects with AIDS. Induced sputum failed in 3 patients, while endoscopy could not be performed (contra-indication, refusal or failure due to lack of cooperation) in 7 patients; a technical failure for BAL was observed in 3/23 cases.
