FIG. 3.

Sequence indicating a portion of the direct repeat region and the IS6110 insertion site of the 2.5-kb PCR fragment from patient no. 2's isolate. Primers used are indicated by bold type, with the name in bold on the 5′ end. Direct repeats are indicated by a single underline, with the spacer number indicated 3′ of the direct repeat just before that number's spacer. The three duplicated nucleotides are indicated by a double underline. The boxed numbers indicate the IS6110 sequences that were deleted.
