The frequency of these two genes in our E. coli collection was also high in strains isolated from patients with UTI symptoms (fimH-98.0% and papC-74.0%), food-derived isolates (fimH-89.5% and papC-73.7%) and from poultry farms (fimH-95.5% and papC-52.3%), which confirms the high adhesive potential of these strains. The gene discussed is PCDH8; the disease is bacterial urinary tract infection.
