Despite being the number one cause of death from an infectious disease, little is known of the 7 phylogenetic lineages of (Mtb). These lineages are thought to have adapted differently to their human hosts, as they are geographically localised. As a result, they show variation at the phenotype level, such as virulence and the ability to develop antibiotic resistance, and at a genomic level, such as in single nucleotide polymorphisms (SNPs). We have linked the differences in SNPs between lineages to differences in metabolites (i.e. what is ultimately produced by a cell). Through multi-omic integration of these datasets we have discovered lineage-specific metabolomic changes, potentially as a result of genomic adaptation. The differences between lineages will provide insight into new biological pathways to target and manipulate in future research.
