Fig. 1From: Genetic variation in Mycobacterium tuberculosis isolates from a London outbreak associated with isoniazid resistancePhylogenetic reconstruction of the outbreak and control strains. All clinical outbreak strains, with the exception of 04.194, cluster together as part of RFL15. All outbreak isolates are of the Euro American (Cameroon) lineage, except sample 04.194, which is of the Euro American (Uganda) lineage. The control strains (05.177, 05:094, and 04.011) diverge as separate and independent strains: Euro American (Uganda) for the former two and East African Indian (Delhi) for the latterBack to article page
