文摘

Most genetic markers occur at equal relative frequencies among clinical and bovine VTEC O157:H7 Argentinean isolates. nle-profiling discriminated 43 O157:H7 isolates into 11 genotypes. Results reaffirm the circulation almost exclusive in Argentina of strains belonging to hypervirulent clade 8- lineage I/II.
