Figure 1From: DNA fingerprinting of Shiga-toxin producing Escherichia coli O157 based on Multiple-Locus Variable-Number Tandem-Repeats Analysis (MLVA)Escherichia coli O157 MLVA Fragment patterns generated from seven VNTR loci showing two identical and one different profile. Comparison of the MLVA profiles of three O157:H7 STEC cattle isolates. These isolates were all identical by previous Xba I PFGE and AFLP typing. The MLVA assay confirmed that isolates 126/97 (upper panel) and 131/97 (middle panel) were identical, but displayed a clearly distinct profile for isolate 127/97 (lower panel).Back to article page
