title: 16s rDNA of Rattus norvegicustolDC+anti
design: DNA was extracted from cecal content of rats, the concentration and purity of DNA were assessed, and DNA integrity was analyzed through 2 % agarose gel electrophoresis. The sequencing library was constructed using TruSeqTM DNA Sample Prep Kit (Illumina), followed by sequencing using Illumina NovaSeq sequencing platform, which was performed by Majorbio Bio-Pharm Technology Co. Ltd. (Shanghai, China).
