Fimbriae and pili are hair-like appendages present on the bacterial cell wall similar to flagella. Microvilli on the surface of white blood cells allow them to migrate. These structures are motile and can beat toward one direction so that they can move the entangle particles from the surface. Cilia are made up of microtubules, which are arranged in (9+2) ultrastructure. Pili or fimbriae are protein structures that extend from the bacterial cell envelope for a distance up to 2 m (Figure 3). These components have specific functions and most of them are found on the apical surface of epithelial cells. Pili are more rigid than fimbriae. The external ends of the pili adhere to a solid substrate, either the surface to which the bacterium is attached or to other bacteria. Hence, they lack (9+2) ultrastructure.

Viruses, on the other hand, do not have flagella or pili. Unlike microvilli, cilia extend slightly into the cell and are anchored via a special structure called basal body, which is made of microtubules. The main difference between fimbriae and pili is that fimbriae are responsible for the attachment of the cell to its substrate whereas pili are responsible for the attachment and horizontal gene transfer during bacterial conjugation.

However, you may visit "Cookie Settings" to provide a controlled consent. Fimbriae facilitate adherence and thus enhance the capacity of the organism to produce disease. Common pili or fimbriae are often involved in adherence (attachment) of bacterial cells to surfaces in nature. Cilia (singular: cilium) are one of the organelles found in eukaryotic cells. Normally, the length of a cilium is around 5 to 10 m and the diameter is about 0.2 m. Type IV pili (T4P) are surface-exposed fibers that mediate many functions in bacteria, including locomotion, adherence to host cells, DNA uptake (competence), and protein secretion and that can act as nanowires carrying electric current.
