Fig:-Peritrichous flagellum seen under light microscope . flagella are very delicate and tend to break off the cells easily when manipulated. Some species of bacteria (such as Spirochetes) have a specialized type of flagellum called an "axial filament" that is located in the periplasmic space, the rotation of which causes the entire bacterium to move forward in a corkscrew-like motion. e.g. Lateral flagella, the third kind of flagella, are often confused with peritrichous flagella, because both flagella grow from the side of the cell body. Well-studied examples include Escherichia coli ( E. coli , Fig. It may begin to rotate clockwise instead. Medical Definition of Peritrichous.
