Cilia (singular - Cilium) are narrow and long hair like protuberances from the apical surface of some epithelial cells. In endospore formation, the bacterium divides within its cell wall. The fimbriae are a shorter version of pili. The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called capsomeres. A small, fringe of finger-like cellular projections and it is located at the end of the fallopian tube is known as fimbria. cilia and pili do provide some common benefits to the bacterial cell like to adhere to a surface, help in movement and gather food. Two types of cilia are found: motile cilia and non-motile cilia. . (9+2) pattern while the core of microvili is made up of microfilament, hence it microvillus. the small intestine and kidney tubule.

Cilia are 5to10 m long and 0.2 m wide. membrane. Cilia are present only in eukaryotic cells and cannot be found on prokaryotes like bacteria. In medical situations, they are major determinants of bacterial virulence because they allow pathogens to attach to (colonize) tissues and, sometimes, to resist attack by phagocytic white blood cells. They are found in gram negative bacteria. Instead of peripherally arranged nice microtubules in a cilium core, the basal body has nine microtubule triplets and has no central microtubules.
