What is the mode of transmission of trypanosomiasis?
The disease is mostly transmitted through the bite of an infected tsetse fly but there are other ways in which people are infected: Mother-to-child infection: the trypanosome can cross the placenta and infect the fetus.
What is trypanosomiasis and what is it vector?
African trypanosomiasis is one of a diverse range of neglected tropical diseases. The tsetse fly, Glossina sp. is the main vector for trypanosomes, the parasites that cause trypanosomiasis. This disease affects both humans and livestock.
What are the two species of tsetse flies that are responsible for the transmission of TB Gambiense?
The tsetse flies are separated into three groups, of which two groups are mainly responsible for the transmission of sleeping sickness: the palpalis group transmitting T.b. gambiense, which is responsible for the chronic form of the disease; and the morsitans group transmitting T.b. rhodesiense, which causes a more …
Which disease is spread by tsetse flies?
There are two types of African trypanosomiasis (also called sleeping sickness); each is named for the region of Africa in which they were found historically. East African trypanosomiasis is caused by the parasite Trypanosoma brucei rhodesiense, which is carried by the tsetse fly.
How do you control animals with trypanosomiasis?
Trypanosomiasis can be controlled by treating livestock with trypanocides or insecticide – killing parasites or vectors, respectively. Mathematical modeling of trypanosomiasis was used to compare the impact of drug- and insecticide-based interventions on R 0 with varying densities of cattle, humans and wild hosts.
What are the prevention of trypanosomiasis?
There is no vaccine or drug for prophylaxis against African trypanosomiasis. Preventive measures are aimed at minimizing contact with tsetse flies. Local residents in endemic countries are usually aware of the areas that are heavily infested and may be able to provide advice about places to avoid.
What are the Control of trypanosomiasis?
What is the epidemiology of trypanosomiasis?
The epidemiology of the disease is mediated by the interaction of the parasite (trypanosome) with the vectors (tsetse flies), as well as with the human and animal hosts within a particular environment.
Is there a sleeping sickness?
Parasites – African Trypanosomiasis (also known as Sleeping Sickness) African Trypanosomiasis, also known as “sleeping sickness”, is caused by microscopic parasites of the species Trypanosoma brucei. It is transmitted by the tsetse fly (Glossina species), which is found only in sub-Saharan Africa.
Is Trypanosoma a protozoa?
Trypanosoma is a genus of kinetoplastids (class Trypanosomatidae), a monophyletic group of unicellular parasitic flagellate protozoa.
