Metagenomic sequencing of Mus musculus: oral swab sample
Oral swab samples were collected from Mus musculus under sterile conditions. Microbial DNA was extracted using the QIAamp DNA Microbiome Kit (Qiagen) according to the manufacturer's protocol. Sequencing libraries were constructed with the Illumina Nextera XT DNA Library Preparation Kit and sequenced on the Illumina NovaSeq 6000 platform, producing paired-end reads (2  150 bp).
