The Kinetoplastea ( Syn .: Kinetoplastida) form a class of flagellated unicellular organisms ( flagellates ); they belong to the Euglenozoa . Many kinetoplasts are parasites .
description
The kinetoplastea have a single large mitochondrion in which the so-called kinetoplast is located: a large amount of fibrillary DNA (kDNA), which is often closely related to the base of the flagellum .
ecology
Many kinetoplastea are parasitic, such as the species Trypanosoma brucei , a parasite in humans that causes sleeping sickness . The carrier here is the tsetse fly . Another type of kinetoplastidea that is dangerous to humans is Trypanosoma cruzi , which causes Chagas disease (see also: Trypanosomes ).
Systematics
Traditionally, the Kinetoplastea were divided into the two suborders Bodonida and Trypanosomida. Adl et al. divide the group based on new findings as follows:
- Prokinetoplastina with Ichthyobodo and Perkinsellia
- Metakinetoplastina
