Hemolytic uremic syndrome caused by verotoxin-producing Escherichia coli O26. Case report.

Verotoxin-producing Escherichia coli (VTEC) are nowadays among the most important emerging group of food-borne pathogens (VTEC strains cause gastroenteritis that can be complicated by the hemorrhagic colitis or hemolytic uremic syndrome, HUS). Escherichia coli 026 producing verotoxin 2 was isolated and its identity confirmed by examination of phenotype and genotype; the strain was first described in Slovakia in association with the development of HUS in a 4-year-old girl.
