Fig. 2
Median network of 144 Mycobacterium tuberculosis isolates. The size of the circles is proportional to the number of cases of each genotype. A) Clades representing determined lineages from the global M. tuberculosis tree are indicated in the figure (Lineage 1: EAI, Lineage 2: Beijing, Lineage 4: LAM, X and Haarlem). The 27 hypothetical clusters of transmission are also indicated and numbered in dashed lines (I-XXVII). B) Vulnerable populations in the dataset (homeless, HIV infected and immigrants). The 27 hypothetical clusters of transmission are indicated in dashed lines. Countries of origin of immigrants are indicated as CPV (Cape-Verde), ROU (Romania), AGO (Angola), VEN (Venezuela), UKR (Ukraine), BRA (Brasil), BGD (Bangladesh) and CHN (China)
