Biomarker signatures of M. africanum tensor sublineages Spoligotype and MIRU signatures of tensor sublineages of M. africanum strains. White indicates probability of 0 and black indicates probability of 1. Intermediate colors represent probabilities in the range (0,1). MA1 and MA4 are similar in their MIRU signatures, and MA4 strains lack spacers 22 through 24, in addition to the deletions of MA1 strains. MIRU signatures of MA2 and MA3 strains are also similar, and MA2 has an extra deletion, 21 through 24, in addition to the deletions of MA3 strains.
