Sorbitol-fermenting shiga toxin-producing E. coli O157:H- strains have emerged as a cause of human disease in many European and non-European countries. The role of SF VTEC O157:H- in the etiology of pediatric HUS and diarrhea is significant. We characterized the first SF VTEC O157:H- strain isolated from 9 year old patient in Poland. Strain possessed many traits characteristics for SF VTEC O157:H-. It fermented sorbitol after overnight incubation and produced beta-glucuronidase. It possessed the stx2, eae-gamma, EhlyA and sfpA genes and did not harbour plasmid-encoded katP and espP genes. Motility was not expressed but the strain possessed the chromosomal fliC locus for H7 antigen. The spread of SF VTEC O157:H- strains demonstrates the need for appropriate procedures for their microbiological diagnosis in Poland.
