Planktonic Growth of Pseudomonas aeruginosa around a Dual-Species Biofilm Supports the Growth of Fusobacterium nucleatum within That Biofilm

Figure 2

Distribution of major bacterial genera found within biofilms on the TT by deep parallel pyrosequencing. Numbers indicate the percentage of each genus present on the TT from (a) right ear and (b) left ear. Pseudomonas and Streptococcus are facultative anaerobes; Fusobacterium, Peptostreptococcus, and Parvimonas are obligate anaerobes; Eikenella is a microaerophile (preferring 10% oxygen, 10% carbon dioxide). “Other bacteria” represent genera present at less than 2.5% each. The identities and relative abundance of these organisms are provided in Table 2.
