Resumen:
The aim of this work was to adapt described MLVA protocols to the molecular typing and
characterization of VTEC O157:H7 isolates from Argentina. Nine VNTR loci were amplified by PCR
showing diversity values from 0.49 to 0.73. Nine MLVA profiles were observed and the cluster analysis
indicated both unrelated and closely related VTEC O157:H7 strains. In spite of the limited number of
isolates studied, the panel of VNTR used made it possible to perform a first approach of the high genetic
diversity of native strains of O157:H7 by MLVA.
