HOT designations were defined according to the Human Oral Microbiome Database (HOMD) classification scheme. (), Total numbers of HOT, including singletons, are presented inside brackets. aUncultivated phylotypes were identified based on the HOMD classification. The numbers of phylotypes representing HOT designations with >200 16S gene counts (corresponding to >0.3% of total 16S counts) are presented in these columns. bAll HOT designations (including those that were represented by 1 to 200 copies of16S gene reads). ND, no uncultivated HOMD representative was detected.
