The Mycobacterium tuberculosis Mtb-fpg1 region contains variable numbers of repeat units. (a) Organization of the repetitive elements in M. tuberculosis H37Rv. The start of the repetitive structure is located 40 bp after the stop codon of rnc and ends at the start codon of Mtb-fpg1. Arrows indicate length of the repeats. In direct repeat 18 bp, 16 out of 18 consecutive base pairs are identical to direct repeat 16 bp. (b) Variation in the rnc-Mtb-fpg1 intergenic region in M. tuberculosis isolates monitored by PCR amplification. Number indicates PCR product size/repeat type according to (c). (c) The organization of the different types of M. tuberculosis Mtb-fpg1 tandem repeat regions found in 32 M. tuberculosis strains. Arrows as in (a).
