WebDespite their differences in length and number, flagella and cilia share a common structural arrangement of microtubules called a “9 + 2 array.” This is an appropriate name because a single flagellum or cilium is made of a ring of nine microtubule doublets, surrounding a single microtubule doublet in the center ( Figure 4.26 ). WebApr 2, 2024 · The flagella-mediated motility and chemotaxis-mediated motility are also considered as virulence factors and the extent as well as the degree of motility differ among different bacterial species. Furthermore, the location of spirochetal flagella varies, e.g. T. denticola is in the periplasmic space, while other bacteria exhibit exposed flagella ...
