[Mannose-resistant hemagglutination (MRHA), type 1 fimbriae and hemolysin production of urinary and fecal Escherichia coli strains].
The prevalence E.coli bearing Mannose-Resistant Hemagglutinating (MRHA) adhesin, Type 1 fimbriae and hemolytic activity was assessed in 103 E.coli strains isolated from 43 male and 60 female adult patients with urinary tract infection. For comparison 83 faecal E.coli strains were also examined for the same properties. MRHA adhesins were present in 58% (60/103) of the urinary strains, and 31% (26/83) of the faecal strains of E.coli. All faecal and 95% (98/103) of the urinary strains of E.coli expressed Type 1 fimbriae. Hemolytic activity was more frequent among urinary strains than among faecal strains (21%, 12%, respectively). The presence of MRHA adhesin and hemolytic activity was found correlated in 13.5% (14/103) of urinary strains whereas only one (1.2%) strain showed these properties together among the faecal isolates.
