(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.

(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.
