Research interest

Research in antibiotic resistance My research activities are focused since 20 years on antibiotic resistance focus on therapeutic strategies especially in aminoglycosides resistance (experience in genetic mobile element, expression of genes in integron structure) in Gram negative bacilli and multidrug resistant N. gonorrhoeae. It involves close collaboration between clinical bacteriologists, infectious disease clinicians and orthopedics to combine task forces together.
