Does Trypanosoma cruzi have nuclei and/or flagella?

cruzi. The transition of trypomastigote to amastigote in T. cruzi takes place without nuclear division and progresses through an intermediate stage (2K1N) with duplicate flagella, basal body and kinetoplast, but only a single nucleus.

What is the morphology of Trypanosoma Gambiense?

gambiense and T. b. rhodesiense, are indistinguishable morphologically. A typical trypomastigote has a small kinetoplast located at the posterior end, a centrally located nucleus, an undulating membrane, and a flagellum running along the undulating membrane, leaving the body at the anterior end.

Is Trypanosoma cruzi flagellated?

During invasion of host cells by Trypanosoma cruzi, the parasite that causes Chagas disease, the elongated, flagellated trypomastigotes remodel into oval amastigotes with no external flagellum. The underlying mechanism of this remodeling and the fate of the flagellum are obscure.

What is the morphology of Trypanosoma brucei?

T. brucei is polymorphic, with three main forms, all of which have a small kinetoplast and a conspicuous undulating membrane: Long slender forms (23–30 μm in length) with a free flagellum, which may be up to one half of the length of the organism. The posterior end is pointed and the nucleus is central.

Does Trypanosoma cruzi have nuclei?

Transcription and replication decrease during transformation in trypomastigotes implicating large alterations in the nuclear structure. Recent evidences also suggest that T. cruzi nucleus respond to oxidative and nutritional stresses.

What are the forms of Trypanosoma?

Two different types of trypanosomes exist, and their life cycles are different, the salivarian species and the stercorarian species.

How many flagella do Trypanosoma have?

one flagellum
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).

How does Trypanosoma cruzi move?

Trypanosoma cruzi trypomastigotes and epimastigotes are propelled by a single flagellum, via mechanochemical oscillations that generate motile forces.

Is Trypanosoma cruzi a bacteria?

Summary: Chagas’ disease is caused by the protozoan parasite Trypanosoma cruzi and causes potentially life-threatening disease of the heart and gastrointestinal tract.
