Présentation

Mes travaux de recherche s’articulent autour de plusieurs axes :

Mécanismes d’adaptation de P. aeruginosa et A. baumannii aux peptides antimicrobiens- Mécanismes de résistance aux antibiotiques des souches cliniques de Pseudomonas spp. et Acinetobacter spp. (épidémiologie, supports génétiques, transferts, caractéristiques phénotypiques)
Substrats et régulation des systèmes d’efflux actif de P. aeruginosa (voies de régulation/signalisation, réponse aux stress)
Evolution phénotypique et génotypique des souches de P. aeruginosa colonisant l’arbre bronchique des patients atteints de mucoviscidose
Mécanismes d’adaptation de P. aeruginosa et A. baumannii aux peptides antimicrobiens
