Figure 4. Non-conventional organisms in BALs are similar to scope and catheter pre-washes, but different from paired mouth and throat samples.
A. Relative abundance of non-conventional taxa detected in all 102 BALs (top); and 22 catheter and scope pre-washes, mouth and throat samples (bottom) after CF pathogens (see Table 2) were computationally removed. B. Morisita-Horn dissimilarity of non-conventional organisms in all 102 BALs (after pathogens were removed) as compared to non-conventional organisms in subject-paired scope pre-wash, mouth rinse, and throat aspirate samples. C. Principal coordinates analysis of Morisita-Horn dissimilarities of non-conventional organisms (after pathogens removed) in BAL, mouth rinse, throat aspirate, and instrument control samples described in A. The scope and catheter pre-wash control samples separate into two groups along principle coordinate 1 according to the batch in which they were sequenced.
