The composition of mammalian intestinal microflora is related to many environmental and geographical factors, and it plays an important role in many aspects such as growth and development. Sequencing data of the bacterial 16S rRNA gene from sable (Martes zibellina) samples using next-generation sequencing technology are limited. In our research, 84,116 reads obtained by high-throughput sequencing were analyzed to characterize and compare the intestinal microflora of wild sables and housed sables. Firmicutes (31.1 %), Bacteroidetes (26.0 %) and Proteobacteria (21.5 %) were the three most abundant phyla present in wild sables, whereas Firmicutes (55.6 %), Proteobacteria (29.1 %) and Actinobacteria (6.0 %) were the three predominant phyla present in housed sables. At the phylum level, wild sables exhibited a significant difference in the relative abundances of Bacteroidetes and Actinobacteria, whereas housed sables only exhibited significant changes in TM7 at the phylum level, and Clostridia, at the class level. The predominance of Bacteroidetes in wild sables warrants further research. These results indicate that a sudden change in diet may be a key factor that influences fecal bacterial diversity in mammals.
