Figure 3. Selecting helpers to isolate the uncultivable organism Tannerella sp. OT286.

Figure 3

Red edges in the networks show yellow nodes connecting directly to Tannerella sp. OT286. The length of the edges is proportional to the strength of the association between species. Oral taxon (OT) for each species/phylotype followed the designation provided in Human Oral Microbiome Database (HOMD) www.homd.org. a) Connections in module turquoise from HOMIM results healthy cluster 1 (51 samples). b) Connections in module red from HOMIM results healthy cluster 2 (37 samples). c) Connections in module grey from HOMIM results from diseased cluster 1 (467 samples). d) Connections in module grey from HOMIM results from diseased cluster 2 (49 samples). In red we show the strains that were tested as helpers in our experiments. Additionally, as negative controls, we tested 2 strains not present in those networks: Propionibacterium acnes OT530 and Lactobacillus casei OT568.
