The cells are surrounded by a polysaccharide glycocalyx (slime) through which fimbriae sometimes protrude at the cell poles. The slime forms a common matrix for the cell population when growth occurs in swarms on solid surfaces. Underneath the slime layer is a cell envelope consisting of an ...
Chemotaxis in bacterial cells is also discussed. The nature of motility in spirochetes and the mechanism of gliding motility are also discussed. A description of the structure and function of pili (fimbriae) are followed by a role for these structures in twitching motility.Albert G. Moat...
In biology, the terms hair cell types generally constitute sensitive terminals of such cochlear and neurological processes that have been prevalent inside the ears among every mammal. It uses signal transduction pathways to monitor mobility inside the surroundings. They can be detected inside...
(fimbriae) rigid appendages that are more abundant and shorter than flagella, used for attachment and motility cilia short, hair-like structures that are shorter than flagella and used for movement on the cell surface microvilli membrane extensions on the surface of eukaryotic cells that increase ...
[1,60,61]. Another extracellular structure which is crucial in the process of colonization of the intestinal mucosa is represented by appendices called fimbriae or pili, found in both enteric and oral bifidobacteria [21,62–64]. They can be involved in the establishment of host cell contact ...

Pili (or fimbriae) are long filamen- tous structures that extend from the surfaces of various Gram-negative and Gram-positive bacteria. Most studies on pili in Gram-positive bacteria have been conducted on pathogenic species, including streptococci, entero- cocci, corynebacteria, and bacilli [160...
The cell wall of Gram-positive bacteria is a complex assemblage of glycopolymers and proteins. It consists of a thick peptidoglycan sacculus that surrounds the cytoplasmic membrane and that is decorated with teichoic acids, polysaccharides, and proteins.
