Locomotion. Trypanosomes move actively and progress by movement of the undulating membrane and the free flagellum (when present), which acts as a kind of propeller, thus drawing themselves through the blood plasma or tissue fluid. (The free flagellum, when present, arises from the anterior [front] end of the parasite.)

Are Trypanosoma capable of locomotion?
The unusual spiral motility of trypanosomes, also observed in treponemes and other spirochetes with attached flagella (7), is an extremely efficient means of cell locomotion and is thought to facilitate movement through very viscous environments (34), such as the bloodstream and connective tissues of the mammalian host ...
Do Trypanosoma have flagella?
Trypanosomes are flagellated protozoa, responsible for various tropical diseases such as sleeping sickness and Chagas disease. ... The most striking phenomenon is the involvement of the flagellum in several aspects of the trypanosome cell cycle, including cell morphogenesis, basal body migration, and cytokinesis.
How does Trypanosoma cruzi move?
After reproducing through binary fission, the epimastigotes move onto the rectal cell wall, where they become infectious. Infectious T. cruzi are called metacyclic trypomastigotes. When the triatomine bug subsequently takes a blood meal from a host, it defecates - its waste containing T.
What is the structure of Trypanosoma?
T. brucei is a typical unicellular eukaryotic cell, and measures 8 to 50 μm in length. It has an elongated body having a streamlined and tapered shape. Its cell membrane (called pellicle) encloses the cell organelles, including the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes.
How many flagella Trypanosoma have?
Each T. brucei cell contains one flagellum that moves the cell body in an alternating right and left-handed twist resulting in bihelical motion (11) (Movie S1).
What is the flagella function?
Flagellum is primarily a motility organelle that enables movement and chemotaxis. ... In addition to motility, flagella possess several other functions that differ between bacteria and during the bacterial life cycle: a flagellum can, for example, participate in biofilm formation, protein export, and adhesion.
How would a flagellum help Trypanosoma?
A central feature of trypanosome biology is the single flagellum of the parasite, which is an essential and multifunctional organelle that facilitates cell propulsion, controls cell morphogenesis and directs cytokinesis.
Does the Amastigote have a flagellum?
In contrast to promastigotes, which contain a long and motile flagellum, the amastigote form of Leishmania displays a short flagellum without a PFR that is limited to the flagellar pocket domain.
Is Trypanosoma cruzi motile?
Trypanosoma cruzi trypomastigotes and epimastigotes are propelled by a single flagellum, via mechanochemical oscillations that generate motile forces.
What is the infective stage of Trypanosoma?
The infective stage happens in salivary glands. There they undergo the transformation and the product formed is a somewhat short and stumpy infective stage. Then after becoming infected, they are passed onto humans through biting and infection occurs.
What is the infective stage of Trypanosoma cruzi?
The parasites multiply and differentiate in the midgut and differentiate into infective metacyclic trypomastigotes in the hindgut . Trypanosoma cruzi can also be transmitted through blood transfusions, organ transplantation, transplacentally (from mother to unborn baby), and in laboratory accidents.
What are the adaptive features of Trypanosoma?
Trypanosomes are highly adapted for life in the hostile environment of the mammalian bloodstream, and have various adaptations to their cell biology that facilitate immune evasion. These include a specialized morphology, with most nutrient uptake occurring in the privileged location of the flagellar pocket.
What are the stages of Trypanosoma?
Infection occurs in two stages, an initial haemolymphatic stage followed by a meningoencephalitic stage after the trypanosomes invade the central nervous system (CNS). However, many of the signs and symptoms are common to both stages, making it difficult to distinguish between the two stages by clinical features alone.
What features of Trypanosoma make it fall under the kingdom Protista?
Trypanosoma is classified under the Kingdom Protista because it is unicellular eukaryotes. It has well defined nucleus with nuclear envelope, membrane bound organelles, 80S ribosomes and flagella with 9 + 2 organisation.
