pilus Bacteriol.|ˈpaɪləs|
Pl. pili.
[L. pilus hair.]
Any of the several types of filamentous appendages, other than flagella, that are facultatively produced by some bacterial cells.
1959C. C. Brinton in Nature 21 Mar. 782/2 Pili have been called by several different names: ‘fine threads’, ‘bristles’, ‘fimbriæ’, and ‘filaments’. It is felt that the word ‘pilus’ is the most descriptive term, since the pili usually cover most of the bacterial surface and are continually growing out in a manner quite analogous to hair or fur. 1969A. M. Campbell Episomes iii. 36 Of the various types of pili formed by enteric bacteria, F-pili are distinguishable by the specific adsorption of male-specific bacteriophages to their surfaces. 1975Ann. Rev. Microbiol. XXIX. 104 Once mating pairs were formed, phage f1 failed to interfere with the conjugation event, suggesting the involvement of the pilus..in the transfer of bacterial DNA. 1976P. Collard Devel. Microbiol. viii. 108 A number of pilus-specific phages have been discovered. |
