Fig. 1From: New epidemic cluster of pre-extensively drug resistant isolates of Mycobacterium tuberculosis Ural family emerging in Eastern EuropeML consensus phylogenetic tree of 149 M. tuberculosis Ural family strains (CAS family strain was used as outgroup) based on 6002 genome-wide variable amino acid positions. Strain designation includes consecutive number (Additional file 1: Table S1), country of origin, drug resistance. Abbreviations: RU – Russia, MD – Moldova, BY – Belarus, MDR – multidrug resistance, H – isoniazid resistant, E – ethambutol resistant, S – streptomycin resistant, P - pyrazinamide resistant, sus – susceptible, # - pre-XDR, ## - XDR. *- genotypic resistance profile confirmed by phenotypic data (when available at GMTV database http://mtb.dobzhanskycenter.org/). The CAS strain was used as outgroup under phylogenetic analysis; it did not have any drug resistance mutationBack to article page
