Résistance aux antifongiques azolés d’origine environnementale : quelles alternatives pour l’avenir ?
Azole resistant Aspergillus fumigatus strains are increasingly reported in many countries. One resistance mechanism is attributed to the use of azole fungicides in environment. Two mutations, TR34/L98H and TR46/Y121F/T289A, on the cyp51A gene, have been described. Results of 40 publications about azole resistant strain detections, with TR34/L98H and TR46/Y121F/T289A mutations, in clinical and/or environmental samples, are presented in this review. These cases, observed in many countries, suggest spreading phenomenon. Measures to moderate fungicides treatments and/or alternative treatments in environment should be established to preserve the effectiveness of azole antifungal therapy for at-r…
Identification et spécificité d’espèce des protéines d’intérêt pour le diagnostic sérologique de la maladie du poumon d’éleveur d’oiseaux
Introduction La maladie du poumon d’eleveur d’oiseaux (PEO) est une pneumopathie d’hypersensibilite liee a l’inhalation repetee de proteines antigeniques localisees entre autre, dans les fientes des oiseaux. Actuellement on connait peu de chose sur la nature de ces proteines. La serologie occupe une place importante dans le diagnostic, toutefois, celle-ci manque de specificite et de standardisation. Les objectifs consistent a evaluer la specificite des proteines antigeniques impliquees dans le PEO vis-a-vis de differentes especes aviaires et a identifier les proteines d’interet contenues dans les fientes de pigeon. Methodes Une comparaison des proteines des fientes de deux races de pigeon, …
Azole-resistant Aspergillus fumigatus: A global phenomenon originating in the environment?
Abstract Aspergillus fumigatus is the predominant etiological agent of invasive aspergillosis (IA), a difficult-to-manage fungal disease associated with a high case fatality rate. Azole antifungals, particularly voriconazole, have significantly improved the survival rate of patients with IA. However, the clinical advances made possible through the use of medical azoles could be threatened by the emergence of azole-resistant strains which has been reported in an ever-increasing number of countries over the last 10 years. The major resistance mechanism, that combines point mutation(s) in the coding sequence of cyp51A gene and an insertion of a tandem repeat in the promoter region of this gene…
Real-time polymerase chain reaction detection of Lichtheimia species in bandages associated with cutaneous mucormycosis in burn patients
Summary Background Cutaneous mucormycoses, mainly due to Lichtheimia (Absidia), have occurred on several occasions in the Burn Unit of the University Hospital of Lille, France. Aim To investigate the potential vector role of non-sterile bandages used to hold in place sterile gauze used for wound dressing. Methods Mycological analysis by conventional culture, Mucorales real-time polymerase chain reaction (qPCR), and Lichtheimia species-specific qPCR were performed on eight crepe and six elasticized bandages that were sampled on two independent occasions in March 2014 and July 2016. Characteristics of the seven Lichtheimia mucormycoses which occurred in burn patients between November 2013 and…
