Marie Desnos-Ollivier is research engineer at the National Reference Center for invasive Mycoses & Antifungals since 2004. She is in charge of phenotypic and molecular identification, antifungal susceptibility determination and genotyping of yeasts causing invasive human infections and curator of the sequences database Institut Pasteur FungiBank. Her main research interests concern the population structure and the molecular epidemiology of Cryptococcus neoformans species complex and genetic relationship between isolates belonging to rare yeast species involved in grouped-cases of invasive infections. She is review editor for Frontiers in Cellular and Infection Microbiology, session Fungal Pathogenesis ; member of the ISHAM working group for Genotyping C. neoformans and C. gattii (Cryptococcus neoformans MLST database) and participate to the ISHAM ITS database.
Genomic studies of grouped cases involving rare yeast species
Genotyping method such as microsatellites and MultiLocus Sequence Typing (MLST) are frequently used to confirm the link between isolates responsible of invasive infections. But these methods are only available for frequent fungal species. For […]
Epidemiological studies on invasive fungal infections
Compared with other infectious diseases, invasive mycoses are neglected diseases. They remained poorly known, underdiagnosed and understudied in many countries around the world despite the increasing public health burden they represent now. The population […]
Phylogenetic studies on fungi causing invasive infections
Why is it important to study the phylogeny of pathogenic fungi. Identification of fungi relied for many years on macroscopic and microscopic morphology on different culture media, it is now almost completely based on […]
Databases on the epidemiology of invasive fungal infections in France
A nationwide network of dedicated clinicians and microbiologists/mycologists composing the French Mycoses Study Group who diagnose and treat the patients with invasive fungal infections contribute to the surveillance programs by notifying their cases through […]
Institut Pasteur FungiBank
Institut Pasteur FungiBank is a multi-locus database on pathogenic fungi of medical interest identified at the French National Reference Center for Invasive Mycoses and Antifungals. Reliable identification of clinical isolates is a key factor for […]
