Table 2. Repeat expansion or reduction in Y. pestis KIM D27.

Type	KIM 10+ coordinates	Size in KIM 10+ (bp)	KIM D27 coordinates	Size in KIM D27 (bp)	Coding	Comment
VNTR	125066–125542	476†	125066–125429	363	N	Tandem repeat. Five copies in KIM 10+; four in KIM D27.
VNTR	704203–704423	220†	704091–704433	342	N	Repeat area expanded in D27.
Expansion*	3346556–3346654	98	3245775–3245890	115	N	17 bp insertion (TTTCTATCTATGTTGTTA) extends N-term of modE(y3040)
IS Element	4232115–4232834	719†	4131351–4132781	1430	Y	Tandem repeat of IS154. One copy in reference, two copies in PCR.
VNTR*	4328042–4329222	1180	4227881–4233335	5454	Y	Multiple copies of a 289 bp motif; PCR results in ladder effect in y3884

^†Based on published sequence. PCR reactions showed these sites were the same length in KIM 10+ DNA as was observed for KIM D27.

^*These sequences were different between KIM 10+ and KIM D27.
