The slide was examined under 1000r magnification, and the number of flagella counted for each exflagellating gametocyte. Lateral flagella were not clearly visible, but 2-5 polar flagella (2-3 times the length of the cell) were observed. It is known that the flagella perform a propeller-like movement with a specific handedness resulting from the gear-like structure of their molecular motors. Zoospores narrowed down toward the forward end and had two flagella. Specific targeting of proteins to the flagella of trichomonads thus may be modulated by an alternative mechanism. Monoclonal antibodies specific for an acetylated form of a-tubulin recognise the antigen in cilia and flagella from a variety of organisms. Metacyclic promastigotes were readily distinguished in fresh preparations by their small cell bodies, long flagella and vigorous motility.

An approach to digital image analysis of bending shapes of eukaryotic flagella and cilia. Interestingly, the spirochetes and not the relatively small flagella propel the cells. We estimated c=5 from observations of the modal number of flagella emerging from male gametocytes. Transition of bacterial flagella from helical to straight forms with different subunit arrangements. Proximodistal fusion of these flagella with a median cytoplasmic extension gives rise to the spermatozoon. Thus, flagella are normally incorporated into the egg but may be lost during processing.
