Figure 2From: DNA fingerprinting of Shiga-toxin producing Escherichia coli O157 based on Multiple-Locus Variable-Number Tandem-Repeats Analysis (MLVA)Sequence alignment of the Vhec4 VNTR loci from isolates G5300 and IHE5344. The results from the sequencing show that the electrophoretic mobility shift between isolates IHE5344 (upper strand) and G5300 (lower strand) is caused by different numbers of AAATAG repeat units alone.Back to article page
