*The V1/V2 hypervariable region of the 16S rRNA bacterial gene was amplified by PCR and BLAST ( was used to align the patient’s sequences with reference sequences in GenBank. †Percentage identity with the 16S rRNA bacterial sequence from patient blood. ‡Confidence refers to level of curation for each reference sequence identified by using BLAST. Published indicates sequence record associated with peer-reviewed manuscript; RefSeq indicates records from curated GenBank RefSeq database (; Type indicates sequence from type material; unpublished indicates minimally curated direct submission to GenBank not associated with a peer-reviewed manuscript.
