Number of specific SNP referred to SNP with M.tb mostly appearing in 3 lineages and 11 sublineages. Common SNP indicated the same specific SNP reported by Coll et al. [4]
The evolutionary tree shows that the lineage marked with “*” belongs to the branch of Beijing lineage 2.2.1, but it has not been marked in previous studies (such as 2.2.1.1, 2.2.1.2, 2.2.1.3)
