Profiles and seasonal distribution of airborne fungi in indoor and outdoor environments at a French hospital

2009

International audience; A one-year prospective survey of fungal air contamination was conducted in outdoor air and inside two haematological units of a French hospital. Air was sampled with a portable Air System Impactor. During this period of survey, the mean viable fungal load was 122.1 cfu/m(3) in outdoor air samples, and 4.1 and 3.9 cfu/m(3) in samples from adult and pediatric haematology units, respectively. In outdoor samples, Cladosporium was the dominant genus (55%) while in the clinical units, Penicillium sp. (23 to 25%), Aspergillus sp. (15 to 23%) and Bjerkandera adusta (11 to 13%) were the most frequently recovered airborne fungi. The outdoor fungal load was far higher in autumn…

Dynamics of fungal colonization in a new medical mycology laboratory

2012

International audience; Objective of the study. - Study of the spatio-temporal fungal colonization in a new medical mycology laboratory. Methods. - A 17-month survey of airborne fungal contamination was conducted in a new medical mycology laboratory at a tertiary care university hospital. This survey was implemented at three different periods: before the new premises were occupied (period A), during the move into the new laboratory (period B) and after resumption of the mycological activities in these new premises (period C). Results. - During period A, the airborne fungal load ranged from 2.3 to 6 cfu/m(3). The most frequently recovered airborne fungi were Penicillium spp. (75 to 100%). Du…

Épidémiologie de populations de Fusarium oxysporum et F. dimerum en milieu hospitaliers à Dijon et Nancy

2014

Fusarium oxysporum et F. dimerum sont des champignons d'origine tellurique présents dans de nombreux écosystèmes terrestres mais ils ont été récemment détectés dans les systèmes de distribution d'eau de bâtiments hospitaliers1. Une enquête épidémiologique incluant divers bâtiments hospitaliers sur différents sites, des complexes non-hospitaliers et des maisons individuelles a été menée pendant deux ans dans deux villes françaises, Dijon et Nancy. Les champignons ont été détectés seulement dans les canalisations de bâtiments hospitaliers et n'ont pas été détectés dans celles des autres immeubles ni dans l'eau du réseau urbain. Cette distribution surprenante s'explique par une combinaison de …

Adaptation of Fusarium oxysporum and Fusarium dimerum to the specific aquatic environment provided by the water systems of hospitals.

2015

SPE IPM MERS EA; International audience; Members of the Fusarium group were recently detected in water distribution systems of several hospitals in the world. An epidemiological investigation was conducted over 2 years in hospital buildings in Dijon and Nancy (France) and in non-hospital buildings in Dijon. The fungi were detected only within the water distribution systems of the hospital buildings and also, but at very low concentrations, in the urban water network of Nancy. All fungi were identified as Fusarium oxysporum species complex (FOSC) and Fusarium dimerum species complex (FDSC) by sequencing part of the translation elongation factor 1- alpha (TEF-1a) gene. Very low diversity was …

Fusarium species recovered from the water distribution system of a French university hospital

2012

Abstract Dijon Hospital is a French tertiary care institution undergoing major renovation, and different microbiological controls revealed the presence of Fusarium spp. in the water distribution system. Because some Fusarium spp. can cause life-threatening opportunistic infections in immunocompromised patients, an 8-month survey was conducted in two hospital sites in order to evaluate the prevalence of the fungi in the water system. In 2 units of one hospital site, 100% of the samples of tap-water were positive, with high concentrations of Fusarium spp. (up to 10 5  cfu/L). In the second hospital site, 94% of samples were positive, but generally with lower concentrations. The analysis of tr…

A Clonal Lineage of Fusarium oxysporum Circulates in the Tap Water of Different French Hospitals.

2016

ABSTRACT Fusarium oxysporum is typically a soilborne fungus but can also be found in aquatic environments. In hospitals, water distribution systems may be reservoirs for the fungi responsible for nosocomial infections. F. oxysporum was previously detected in the water distribution systems of five French hospitals. Sixty-eight isolates from water representative of all hospital units that were previously sampled and characterized by translation elongation factor 1α sequence typing were subjected to microsatellite analysis and full-length ribosomal intergenic spacer (IGS) sequence typing. All but three isolates shared common microsatellite loci and a common two-locus sequence type (ST). This S…

Contamination des circuits d’alimentation en eau par Fusarium

2015

La decouverte de micromycetes du genre Fusarium dans le reseau hydrique du CHU de Dijon nous a conduit a mettre en place un protocole hospitalier de recherche clinique (PHRC) dont l’objectif a ete de decrire en prospectif, dans le temps et dans l’espace, la contamination par Fusarium dans l’eau de 2 CHU francais (Dijon et Nancy), a des periodes d’activites de restructuration et de construction. Cette etude a ainsi permis de mettre en evidence la presence chronique de Fusarium spp. dans les circuits de distribution de l’eau de certains bâtiments hospitaliers. Nous avons en effet observe que ces micromycetes etaient « installes » dans le reseau, que leur densite de population variait au cours…
