Attachment of Escherichia coli to urinary sediment epithelial cells from urinary tract infection-prone and healthy children

Abstract

Escherichia coli isolated from patients with recurrent urinary tract infections were tested for ability to attach to human urinary sediment epithelial cells in vitro. Higher mean capacity to bind bacteria was found for epithelial cells of the patient from whom the E. coli strain had been isolated than for epithelial cells from subjects without a history of urinary tract infection. The 2 populations were age matched. No relation was found between the age of the cell donor (0 to 15 yr) and the capacity for E. coli attachment.
