A proteinaceous hair-like appendage on the surface of bacteria ranging from 2-8 nm in diameter.
1The transformants subsequently exhibited the ability to form pili and social motility.
2Specific antibody to type 1 pili prevented colonization by the piliated organisms.
3Even the erector pili muscle and the sudoriparous gland are often found.
4Type 1 pili are also critical for colonization and infection in the bladder.
5Other studies have provided the molecular basis of host recognition by CU pili.
6S-motility is mediated by extension and retraction of type IV pili.
7They exchanged information through their pili, passed on bits of memory, and compared notes.
8It is associated with type IV pili, and specialized competence pili mediate DNA uptake.
9Bacterial exposure to the inhibitor led to an almost instantaneous loss of type 1 pili.
10This behavior has been observed in several contexts, including sugar metabolism and pili phase variation.
11The coordinated production of type IV pili and antifungal antibiotics has not been observed previously.
12Mutants lacking cell surface structures, namely type IV pili and the S-layer, do not form biofilms.
13The phenotypes of the strain were also in line with the successful production of TCP pili.
14Our hypothesis is that pili mediate interactions between cells and may thereby directly affect biofilm formation.
15P pili are extracellular appendages responsible for the targeting of uropathogenic Escherichia coli to the kidney.
16Type IV pili are responsible for a diverse range of functions, including twitching motility and cell adhesion.
