Life Cycle of Trypanosoma
The life cycle of Trypanosoma brucei is discussed below:
- The life cycle of Trypanosoma brucei begins when an infected tsetse fly feeds on the blood of a mammalian host, such as a human or animal and introduces infective metacyclic trypomastigotes.
- Once inside the bloodstream, the metacyclic trypomastigotes differentiate into trypomastigotes, which multiply and spread throughout the host’s blood. Trypomastigotes undergo repeated antigen variation and evades the immune system of the host.
- When an uninfected tsetse fly feeds on the blood of an infected mammalian host, it ingests bloodstream trypomastigotes along with the blood meal.
- These trypomastigotes converts into procyclic trypomastigotes in the mid gut of the tse tse fly and differentiate to form epimastigotes that migrate to the salivary gland of the Trypanosoma brucei.
- When this infected tse tse fly bites a healthy human they transmit the pathogent to his blood stream, and complete the life cycle.
Trypanosomes – Diagram, Morphology and Life Cycle
Trypanosoma is a genus of unicellular parasites responsible for diseases like African trypanosomiasis and Chagas disease. These parasites exhibit a distinctive morphology, featuring a long, undulating membrane and a flagellum for motility.
The cell body is elongated with a single nucleus and a kinetoplast containing mitochondrial DNA. Trypanosoma’s life cycle involves transmission through insect vectors, which affect human and animal health in various regions. In this article, we will learn about the morphology and life cycle of the Trypanosoma in detail.
