Type IV pili: Type IV pili are thin, hair-like appendages found in many bacteria. They are involved in various functions, including attachment to surfaces, twitching motility, and DNA transfer. Type IV pili are composed of pilin proteins that assemble into flexible filaments.Bacterial...

Certain functional elements are common to all prokaryotes: the cell wall, the plasma membrane, cytoplasm, ribosomes, and DNA. Additionally, many have sticky polysaccharide capsules, which help them attach to surfaces. 'Fimbriae' and 'pili' are additional prokaryotic structures that aid in adhesion ...

Based on the type of cell wall, they are divided into Gram-negative, Gram-positive, and acid-fast bacteria. Some bacteria also have architectural components such as flagella or pili for movement, cell surface appendages for host interactions, and capsules. Some bacteria form endospores or cysts...
8. Pili Pili are tiny hairlike projections with a tiny hollow-core present over the surface of the bacteria. The common pili are used for adherence and hence, they are important structures of virulence. Some authors describe the common pilus as fimbriae. For example, Neisseria gonorrhoeae uses...
