A prospective cohort study of preschool healthy children (3-6 years old) from two distinct socio-economic settings in the Brussels area, Belgium, was conducted during the years 2006-2008. The objectives were to evaluate nasopharyngeal colonization by Streptococcus pneumoniae, Staphylococcus aureus, Moraxella catarrhalis and Haemophilus influenzae at the(More)
Streptococcus pneumoniae serotype 1 presents a high invasiveness index and is seldom isolated from its niche, the nasopharynx. We report an unusual serotype 1 carriage in a healthy pediatric population at the time of the heptavalent pneumococcal vaccine adoption in Belgium. Our sampling period coincides with an epidemic wave of serotype 1 invasive(More)
BACKGROUND Asymptomatic nasopharyngeal carriage represents an important biological marker for monitoring pneumococcal serotype distribution and evaluating vaccine effects. Serotype determination by conventional method (Quellung reaction) is technically and financially challenging. On the contrary, PCR-based serotyping represents a simple, economic and(More)
Kytococcus schroeteri is a newly described micrococcal species and, to date, has been associated mostly with endocarditis. Six infections attributable to this opportunistic pathogen have been described since 2002, when the first case was identified. We describe here the first pediatric case of a K. schroeteri ventriculoperitoneal shunt infection. The child(More)
Due to long term survival on inert surfaces and frequent resistance to antimicrobial drugs, Acinetobacter baumannii is often responsible for outbrakes of nosocomial infection.1 In a review of A. baumannii outbreaks published between 1977 and 2000, Villegas and Hartstein reported 51 outbreaks, of which 38 occurred in intensive care units (ICUs).2 In such(More)
OBJECTIVES The study objectives were to describe the investigation and management of an imipenem-resistant Acinetobacter baumannii outbreak that occurred in the 15-bed ICU of a tertiary care teaching hospital (Brest, France), during the summer 2008. PATIENTS AND METHODS Patients harboring an imipenem-resistant A. baumannii strain were defined as case(More)
From September to December 2004, contaminations were found in fifteen conservation and transport mediums of corneal grafts at the tissue bank of Brest, including seven by Sphingomonas paucimobilis. The pulsed-field gel electrophoresis made it possible to establish the genotypic profiles of each strain and to compare them. Similarities were found between(More)
OBJECTIVES It is common wisdom that persistent carriage of Staphylococcus aureus is more frequent in young children than in adults. The objectives of this study were to assess the S. aureus temporal carriage pattern among a healthy community of pre-school children, with concomitant description of genotype diversity, toxin-encoding genes and antibiotic(More)
INTRODUCTION We had for aim to describe control and investigation of an outbreak caused by a strain of Extended spectrum beta-lactamase producing Klebsiella pneumoniae in intensive care units of the Brest teaching hospital. PATIENTS AND METHOD The case definition was a patient infected by or carrying the epidemic strain. Control measures and(More)
