WebJul 22, 2024 · Gliding motility: This form of motility is independent of the involvement of the external appendages, i.e. flagellum, pili, or fimbriae. In this kind of translocation, the bacteria propel on a solid surface, without involving cell-to-cell contact as is seen in sliding motility. The exact mechanism of gliding motility is not clearly known. WebFeb 17, 2014 · For these bacteria, two radically different modes of locomotion have evolved: ‘twitching motility’, which involves intermittent, ‘jerky’ cell movements; and ‘gliding motility,’ where the cell motion is smooth.
