Figure 2

P. aeruginosa and multi-drug resistant P. aeruginosa (MDR-PA) outcompete S. aureus and methicillin-resistant S. aureus (MRSA) over the course of CF lung infection. As CF lung disease progresses, oxygen levels decrease coinciding with the use of heme and ferrous iron as predominant sources of iron.
