Trypanosoma is an extracellular blood parasite with a corkscrew-like motion due to its flagellum. It has a complex life cycle involving mammalian hosts and insect vectors. The life cycle begins when an infected tsetse fly or reduviid bug takes a blood meal and transmits the trypomastigote form to mammals. Inside mammals, the parasites multiply and spread through the bloodstream as trypomastigotes before differentiating into epimastigotes inside the insect vector, completing the life cycle.

3.  Introduction
• The name is derived from the Greek. trypano- (borer)
soma (body) because of their corkscrew-like motion.
• Trypanosoma is an extracellular blood parasite.
• Nutrition is by absorption.

4.  Scientific classification
Domain: Eukarya
Kingdom: Protista
Group: Animal-like protista
Phylum: Sarcomastigophora
Subphylum: Zoomastigophora
Class: Zoomastigophorea
Order: Kinetoplastida

Species : brucei, Gambiense,
Rhodesiense, Cruzi

5.  Species
• There are two distinct species of trypanosoma which
cause diseases:
• Trypanosoma Brucei causes sleeping sickness.
• Trypanosoma cruzi causes change disease.

6.  Vectore of trypanosoma
Tsetse fly Rhodnius prolixus

7.  Life Cycle

8.  Locomotion
• Undulating membrane and flagellum both are
used for locomotion.

9.  Distribution
• T. brucei is found where its tsetse fly vectors are
prevalent in continental Africa.
