Fig. 1From: In vivo evolution of drug-resistant Mycobacterium tuberculosis in patients during long-term treatmentMedian-joining networks based on SNPs in Mycobacterium tuberculosis isolates showing microevolution events. The nodes of the networks correspond to the different MTB isolates. The color inside each circle represents the host. Each short line along the lines, linking the nodes corresponds to a single-nucleotide polymorphism (SNP) detected between the variants in the connected nodesBack to article page
