Comparative StudyAssociation between hemolytic uremic syndrome and verotoxin-producing strains of E. coli.
One of the most frequent etiologic agents of Hemolytic Uremic Syndrome (HUS) is Escherichia coli O157H7, a microorganism that possesses virulence factors (Shiga-like Toxins I and II and adhesion fimbriae). The present study was set up to determine the relationship between HUS and the presence of Verotoxin in patients of "Niño Jesús" Children's Hospital. Tucumán, Argentina. 19 Children between 0 and 4 years old suffering from HUS (typical and atypical symptoms) and 15 control children of similar sex and age were selected. ⋯ The 15 control children did not hybridize to the probes assayed. From the results obtained we may conclude that there exists a relationship between HUS and the presence of Verotoxin in the children suffering from HUS studied. The predominant serotype in our cases was O157H7 and Shiga-like Toxin II was found with highest frequency.
