  30. Identification of 16S rRNA sequences • HOMD provides a BLAST search tool for identifying unknown 16S rRNA sequences • The BLAST database contain reference sequences for all categorized human oral taxa • The entire set of reference sequences can be downloaded 2009 IADR, MIAMI, FL, USA

  31. Current Statistics of HOMD 16S rRNA Database • Total number of human oral taxa: 619 • Total number of 16S rRNA reference sequences: 715 • Total number of extended human oral taxa: >1,200* • Total number of extended version of 16S rRNA reference sequence: 1,726 • Classified from a total of >34,000 16S rRNA clonal sequences * In progress 2009 IADR, MIAMI, FL, USA
