Fig. 2.
Phylogeny and selected phenotypes of Pseudomonas aeruginosa lineages IT01, IT02, IT03, IT05, and IT06. Maximum-parsimonious phylogenetic trees were constructed by PAUP* (Methods). Size of swimming, swarming, and protease clearing zones relative to reference strain PAO1 are indicated by colors. Presence of mucoid phenotype is denoted by ‘+’. Ciprofloxacin susceptibility is indicated by ‘S’ (>21 mm clearing zone), ‘I’ (16–20 mm clearing zone), or ´R´ (no clearing zone)
