Dr. Elliott Dasenbrook will review the prevalence of important CF organisms over the last 10 years, the impact of respiratory tract MRSA on survival, the association between a virulent strain of P. aeruginosa that can spread among patients and lung transplant or death, as well as the impact of chronic non-tuberculous Mycobacterial lung disease on lung function.
