(4) P pili mediate the binding of uropathogenic E. coli to a digalactoside receptor determinant present in the urinary tract epithelium.
(5) Uropathogenic Escherichia coli adhere to uroepithelial cells by their digalactoside alpha-D-galactopyranosyl-(1----4)-beta-D-galactopyranose [alpha-D-Galp-(1----4)-beta-D-Galp or Gal alpha (1----4)Gal]-binding pili, which are composed of repeating identical subunits.
(6) Type I pili increased in length much more slowly than did F pili, although the fraction of cells having visible type I pili increased very rapidly after blending because of the large number of type I pili per cell.
(7) A gonococcal pili antigen preparation was used to detect antibody activity sera obtained from 322 culture-positive asymptomatic females and 150 negative controls.
(8) The antigenic surface-associated colonization factor of E. coli strain H-10407 has been further characterized: this pilus-like antigen is produced under conditions of growth that repress the production of common pili of E. coli.
(9) Antigenic variation of gonococcal pili results from the unidirectional transfer of genetic information from variant-encoding partial pilin genes to an active expression locus.
(10) Both motility and the production of pili are transient when initiated in this way.
(11) We also found that the antigens distributed in arrector pili muscles and the walls of muscular vessels were obviously related to the unmyelinated nerve fibers innervating the smooth muscle cells.
(12) The pili of S7 were morphologically, electrophoretically, and immunologically (as far as polyclonal antibody was used) indistinguishable from the 16-kilodalton pili of V. cholerae O1 strain 82P7.
(13) Although pili can form without PapF and PapG, such pili are unable to bind to the digalactoside.
(14) The ability of Typhimurium to adhere to and invade epithelial cells has been associated with flagella, pili of type I and mannose-resistant haemagglutinating activity.
(15) Electron microscopy of negatively stained bacteria was carried out to visualize pili.
(16) Sodium cyanide, azide, and iodoacetate also apparently inhibit f2 adsorption to cells but not to detached F pili.
(17) In course of in vitro passages up to 10. subculture morphological changes of the pili have been observed.
(18) Subunit (pilin) of the purified pili has a molecular weight of about 16,000.
(19) K99+, 987P+, and type 1 pilus+ bacteria could be prevented from adhering to epithelial cells by Fab fragments specific for K99, 987P, or type 1 pili, respectively.
(20) The use of low accelerating voltages and conductive staining procedures allowed us to obtain images of colonization factor antigen I pili and other structural details which were obscured by conventional gold-coating techniques.
