Anne Jamet

Anne Jamet is group leader in the team.
AJ is a medical doctor and clinical microbiologist. She is an associate professor (MCU-PH) in the Unit of « Pathogenesis of Systemic Infections » (U1151-E7, INEM, Paris) and an academic practitioner in the Microbiology Laboratory of the Necker Children’s Hospital. Anne Jamet is in charge of the next-generation sequencing of bacterial genomes at the Necker Hospital since 2013. She is involved in the setting up of the “clinical metagenomic” plateform for microbiological diagnostic at the Necker Hospital allowing direct sequencing of clinical samples in collaboration with the Pathogen Discovery Laboratory (led by Dr Marc Eloit at the Pasteur Institute, Paris).

Besides her clinical activities in the Necker Hospital, she pursues fundamental research activities in the U1151 team 7. After having spent several years studying meningococcus biology and the role of polymorphic toxins in colonization, she now primarily focuses on the adaptation of S. aureus during chronic infections. In tight collaboration with the Microbiology Laboratory and the departments of paediatric pneumology and dermatology of the Necker Hospital, the S. aureus research team leverages 2 main disease models of chronic infections: the cystic fibrosis and epidermolysis bullosa models.

Performance of clinical metagenomics in France: a prospective observational study

11/12/2023Performance of clinical metagenomics in France: a prospective observational studyJacques Fourgeaud et al. Lancet Microbe 2023 Background Metagenomic next-generation sequencing (mNGS) allows untargeted identification of a broad range of pathogens, including rare or novel microorganisms. Despite the recognition of mNGS as a valuable diagnostic tool for infections, the most relevant indications for this innovative strategy ...

Airway environment promote Staphylococcus aureus chronic lifestyle

11/12/2023Airway environment drives the selection of quorum sensing mutants and promote Staphylococcus aureus chronic lifestyleXiongqi Ding et al. Nat Commun 2023 Staphylococcus aureus is a predominant cause of chronic lung infections. While the airway environment is rich in highly sialylated mucins, the interaction of S. aureus with sialic acid is poorly characterized. Using S. aureus USA300 as well as clinical isolates, we ...
