Isolation of TM7. (A) Workflow of TM7 isolation procedure that resulted in low- and high-enrichment groups (LE and HE). TM7 strains were isolated from saliva using a high-throughput 96-well plate host baiting technique. (B) Neighbor-joining tree of TM7 isolates in the HE group (highlighted in red). The tree was produced from aligned full-length 16S rRNA sequences of representative strains using MEGA X. Designations G1 to G6 are the TM7 class-level groups, as previously described. HMT numbers are shown according to the eHOMD.
