Blocking adherence of uropathogenic Escherichia coli isolate to HEP-2 cells and bladder of mice in the presence of antibody against p-fimbriae

Biologicals. 2007 Apr;35(2):99-105. doi: 10.1016/j.biologicals.2006.03.012. Epub 2006 Jul 31.

Abstract

Presence of fimbriae on Escherichia coli isolated from the urine of patients with urinary tract infection was related to the ability of the bacteria to attach to human uroepithelial cells. One of the 50 isolates that expresses high MRHA p-fimbriae, selected and antibody against p-fimbriae from it, showed blocking of attachment of bacteria to HEP-2 cell in 1:1024 titer. Also, 1:512 titer of this antiserum to blocking of attachment in bladder tissue of mice is significant.
