Two Cases of Human Urinary Tract Infection Complicated by Hemolytic Uremic Syndrome Caused by Verotoxin-Producing Escherichia coli

Abstract
In 1993, 2 cases of urinary tract infection (UTI) caused by verotoxin-producing Escherichia coli were diagnosed at Rigshospitalet in Copenhagen, Denmark. Neither of the patients had any previous history of diarrhea. We suggest that E. coli strains isolated from UTI be examined for the production of verotoxin when hemolytic uremic syndrome is clinically suspected.
