FIGURE 2.

Phylogenetic tree for the 354 Mycobacterium tuberculosis isolates from Shanghai, China, 2009–2018. The purple triangles represent isolates from relapsed cases (n = 9). The pink five-pointed stars indicate the clustered isolates, whose genetic distance is ≤12 single-nucleotide polymorphisms (SNPs). The outer ring shows the census register of patients, of which the green represents resident and the orange represents migrant. From inside to outside, the solid colorful circles represent drug resistance mutations for isoniazid, rifampicin, streptomycin, pyrazinamide, amikacin, kanamycin, capreomycin, ethionamide, para-aminosalicylic acid, and linezolid.
