Structure of the flagellar apparatus of heterotrophic flagellate Klosteria bodomorphis Nikolaev et al., 2003 (Kinetoplastea Excavata)

Abstract

The structure of the flagellar apparatus of excavate flagellate Klosteria bodomorphis was considered. Two naked heterodynamic flagella covered with a dense layer of glycocalyx emerge from a single flagellar pocket. The kinetosomes are parallel or at an acute angle to each other. The dorsal and ventral rootlets run from the kinetosomes and produce dorsal and ventral bands which are not connected to each other. The MTR band begins in the wall of the flagellar pocket. The long cytopharynx is reinforced with an MTR band and additional microtubules. A small fibril and a horseshoe-shaped structure lie in the anterior part of the cytopharynx. The vesicular nucleus and Golgi apparatus have the typical structure. The mitochondrion has discoid cristae. The kinetoplast as a compact formation was not found. The similarity between K. bodomorphis and other free-living kinetoplastids is discussed.
