Schematic representation of the six additional esat-6/lhp operon duplications and the regions that surround them in the genome of M. tuberculosis H37Rv. ORFs are represented by blocked arrows indicating direction of transcription, with the different colors reflecting the specific gene family and the length of the arrow reflecting the relative lengths of the genes as in Figure 1. The esat-6 and lhp genes deleted in M. bovis RD07 and RD09 deletion regions [7] are indicated.
