How does Trypanosoma brucei reproduce?

The haploid trypomastigote-like gametes can interact with each other via their flagella and undergo cell fusion (the process is called syngamy). Thus, in addition to binary fission, T. brucei can multiply by sexual reproduction.

How does African trypanosomiasis reproduce?

From the bite, parasites first enter the lymphatic system and then pass into the bloodstream. Inside the mammalian host, they transform into bloodstream trypomastigotes, and are carried to other sites throughout the body, reach other body fluids (e.g., lymph, spinal fluid), and continue to replicate by binary fission.

How does Trypanosoma brucei spread?

brucei. Both forms of sleeping sickness are transmitted by the bite of the tsetse fly (Glossina species). Tsetse flies inhabit rural areas, living in the woodlands and thickets that dot the East African savannah. In central and West Africa, they live in the forests and vegetation along streams.

How does Trypanosoma replicate?

Life Cycle: Inside the host, the trypomastigotes invade cells near the site of inoculation, where they differentiate into intracellular amastigotes . The amastigotes multiply by binary fission and differentiate into trypomastigotes, and then are released into the circulation as bloodstream trypomastigotes .

Where does Trypanosoma brucei come from?

African trypanosomiasis, or sleeping sickness, is caused by Trypanosoma brucei parasites in sub-Saharan Africa and is transmitted by the tsetse fly? (Glossina). American trypanosomiasis, or Chagas disease, is caused by Trypanosoma cruzi parasites in Latin America and is transmitted by the triatomine or ‘kissing’ bug.

What is the life cycle of trypanosomes?

The life cycle of Trypanosoma cruzi involves two intermediate hosts: the invertebrate vector (triatomine insects) and the vertebrate host (humans) and has three developmental stages namely, trypomastigotes, amastigotes and epimastigotes [8].

What is life cycle of trypanosomiasis?

How does Trypanosoma brucei obtain food?

Trypanosomes feed by absorbing nutrients, through their outer membrane, from the body fluids of the host. The proteins, carbohydrates and fats are digested by enzyme systems within their protoplasm.

How does the tsetse fly spread disease?

Sleeping sickness is caused by two types of parasites Trypanosoma brucei rhodesiense and Trypanosomoa brucei gambiense. T b rhodesiense causes the more severe form of the illness. Tsetse flies carry the infection. When an infected fly bites you, the infection spreads through your bloodstream.

What is the life cycle of trypanosomiasis?

How does Trypanosoma cruzi enter the cell?

cruzi can enter the host cell, mainly in macrophages, by phagocytosis. The recognition of Toll-like receptors 2 by trypomastigotes is also capable of inducing a phagocytic process (39) and initiating an inflammatory pathway.
