title: Adhesive properties of P-like fimbriae in Klebsiella-species.
abstract: Clinical isolates of three encapsulated Klebsiella strains with type 1 (mannose-sensitive, MS+MR-), type 3 (mannose-resistant, MS-MR+), type 1.3 (MS+MR+) fimbriae and facultatively coexpressing P-like fimbria were investigated for their ability to adhere to uroepithelial cells (UECs) and tracheal epithelial cells (TECs). Irrespective of the type of epithelial cells, adhesion of the MS+MR+ (type 1.3) fimbriated Klebsiella strain was significantly stronger than adhesion of strains carrying only type 1 (MS+MR-) or type 3 (MS-MR+) fimbriae. The coexpression of P-like fimbriae increased the adhesive properties of Klebsiella strains to UECs but not to TECs. Adhesion of P-like fimbriated Klebsiella strains to UECs was significantly inhibited in the presence of the P+ fimbriae-specific Gal alpha-4-Gal beta (galabiose). Such adhesion was unrelated to the coexpression of type 1, type 3 or type 1.3 fimbriae. However, adhesion to TECs was only moderately inhibited.
