P_mHT_0034S1
cterial genomic DNA was extracted from host buccal or supragingival tissues. PCR amplification of the hypervariable region of the 16S ribosomal RNA (rRNA) genes was performed using the universal bacterial primer pairs. Pairedend metagenomic sequencing was performed on the amplicon libraries using an Illumina MiSeq or HiSeq 2500 systems.
