Bacterial identification using 16S metagenomics approach. Eighty-eight bacterial strains were identified from dog feces. Molecular phylogenetic analysis showing their relationship, including CACC517, CACC537, CACC558, and CACC566, is displayed using the maximum-likelihood method (Ding and Shah, 2007; Guo et al., 2016). Bootstrap values of 500 replicates are shown at the tree nodes, as generated using MEGA 7. The scale bar corresponds to 0.02 units of the number of base substitutions per site (A). Venn diagram plot represents three parts (core, accessory, and strain-specific) of the pan-genome. The center (422), overlapped (2∼4 times) and outer (non-overlapped) indicate the number of core, accessory and strain-specific genes respectively (B).
