What is the Difference Between Trypanosoma Cruzi and Brucei?

🆚 Go to Comparative Table 🆚

Trypanosoma cruzi and Trypanosoma brucei are two different species of parasitic protozoa that cause trypanosomiasis, a disease found in vertebrates due to parasitic protozoan trypanosomes. The main differences between Trypanosoma cruzi and Trypanosoma brucei are:

  1. Diseases they cause: Trypanosoma cruzi is the causative agent of South American trypanosomiasis or Chagas' disease, while Trypanosoma brucei is the causative agent of African trypanosomiasis or sleeping sickness.
  2. Geographical distribution: Chagas' disease is more common in areas such as South America, Central America, and Mexico, which are the primary homes for triatomine bugs. In contrast, African trypanosomiasis is mainly found in western and central Africa, with T. brucei gambiense causing a chronic form of sleeping sickness, and T. brucei rhodesiense causing an acute form of the disease.
  3. Transmission: Both species are transmitted by arthropod vectors, such as Glossina and Triatomine, but they differ in the means of transmission. While T. brucei is transmitted through the saliva of the tsetse fly, T. cruzi is transmitted primarily through the feces of the triatomine bug.
  4. Invasion of host cells: T. brucei is an extracellular parasite during its life cycle, whereas T. cruzi can invade nucleated cells.
  5. DNA mismatch repair proteins: The DNA mismatch repair proteins of T. brucei and T. cruzi act differently in response to DNA damage caused by oxidative stress.

Comparative Table: Trypanosoma Cruzi vs Brucei

Trypanosoma cruzi and Trypanosoma brucei are both parasitic protozoans that cause serious diseases in humans and animals. They have some differences in their life cycles, host preferences, and affect various aspects of their hosts' cells. Here is a table highlighting the differences between the two:

Feature Trypanosoma cruzi Trypanosoma brucei
Life Cycle Digenetic life cycle involving an invertebrate host (triatomine bug) and a vertebrate host (mammals) Digenetic life cycle involving an invertebrate host (tsetse fly) and a vertebrate host (mammals)
Location in Host T. cruzi proliferates inside macrophages and in the cytoplasm of other nucleated cells T. brucei is an extracellular parasite
Symbiont Unknown T. brucei is associated with a bacterial symbiont, Wigglesworthia, which resides in a specialized organelle called the kinetoplast

Both parasites have similarities in their DNA mismatch repair proteins' response to DNA damage caused by oxidative stress. However, their differences in life cycles, host preferences, and location within the host contribute to their distinct pathogenic properties and disease manifestations.
