Translations
pilus
pilus[′pī·ləs] (anatomy) A hair. (biology) A fine, slender, hairlike body. (microbiology) Any filamentous appendage other than flagella on certain gram-negative bacteria. Also known as fimbria. pilus
pilus [pi´lus] (L.) 1. hair. adj., adj pi´lial.2. one of the minute filamentous appendages of certain bacteria associated with antigenic properties and sex functions of the cell. Called also fimbria. adj., adj pi´liate.pi´li cunicula´ti a condition characterized by hairs" >burrowing hairs.F pilus in bacterial genetics, a hollow tubular pilus possessed by (male) F+ cells, the carrier of the F plasmid (fertility plasmid). It forms a connection with a (female) F− cell in bacterial conjugation to allow the transfer of genetic material.pi´li incarna´ti a condition characterized by hairs" >ingrown hairs.pi´li tor´ti a condition characterized by hairs" >twisted hairs.pi·lus, pl. pi·li (pī'lŭs, pī'lī), [TA] 1.
See also: conjugative plasmid. Synonym(s): hair (1) 2. A fine filamentous appendage, somewhat analogous in function to the flagellum, which occurs on some bacteria. Although they can be chemically similar to flagella, pili consist only of protein and are shorter, straighter, and more numerous. Specialized pili (F pili, I pili, and other conjugative pili) seem to mediate bacterial conjugation and bacterial attachment to host cells during the infective process.

Synonym(s): fimbria (2) [L.] pilus (pī′ləs)n. pl. pi·li (-lī′) A hair or hairlike structure, especially a proteinaceous structure projecting from the surface of a bacterium that is smaller than a flagellum and functions in DNA transfer during conjugation and, usually with other such structures, in adhesion.pi·lus, pl. pili (pī'lŭs, -lī) [TA] 1. One of the fine, keratinized, filamentous epidermal growths arising from the skin of the body of mammals except the palms, soles, and flexor surfaces of the joints; the full length and texture of the hair varies markedly in different body sites. 2. A fine filamentous appendage, somewhat analogous to the flagellum, that occurs on some bacteria.
Synonym(s): fimbria (2) .
See also: conjugative plasmid[L.]pilus a hair-like structure on the surface of bacteria which may be associated with bacterial CONJUGATION (the sex pilus) or with adhering bacteria to surfaces. See also FIMBRIA.PILUS
