Group information of HMA-SD rat models. After 5 days of adaptation, human fecal suspension was intragastrically administered every 2 days three times to build the HMA-rats model. Then, the 16 HMA-SD rats were randomly divided into 3 groups for a 8-week trial. The normal chow (NC) group, 8 weeks of NC and daily administration of sterile water gavage, as negative control; the high-fat diet (HFD) group, 8 weeks of HFD and sterile water gavage; the BB-12 group, 8 weeks of HFD and BB-12 gavage. HMA-SD, human microbiota-associated-Sprague-Dawley; SW, sterile water; TKM, Tibet kefir milk; 16S rRNA, 16S ribosomal RNA. Yellow triangle up solid, sampling sites for 16S rRNA sequencing; red triangle up solid, sampling sites for serum lipid profile.
