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

Figure 1

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