title: sequences of bacteria
design: DNA was sequenced and primers (pre-primer sequence 5, -ACTCCTACGGGAGGCAGCA-3, post-primer sequence 5, -GGACTACHVGGGTWTCTAAT-3) were used to amplify the V3 and V4 regions of the 16S rRNA gene. After sequencing library preparation, the MiSeq Reagent Kit V3 (Illumina, USA) was used to perform paired-end sequencing on a MiSeqPE344 sequencer (Illumina, USA).
