Characterization of O157:H7 strains from beef and environment from butcher shops PFGE analysis showed high genetic diversity than SNP. SNP analysis separated the strains in two distinct lineages 8 and 6. The almost exclusive circulation of clade 8 strains in the type of samples analyzed. Not suitable to reduce the pathogenic potential of strains only to the clade type
