• Why is this specific clonal group endemic to North America?
• Is it adapted to our environment?
• Is it more virulent than reference strains?
• Why did it recently emerged? • Experimental Strategy :
• Comparative genomic analysis (New generation sequencing methods).
• Comparative analysis of virulence using in vitro and in vivo models. PHO
