Answer 1

Correct Answer - Option 3 : Tsetse fly

The correct answer is Tsetse fly.

• The trypanosomes are transmitted by tsetse flies.
  • An interesting feature is a remarkable tolerance to nagana pathology shown by some breeds of cattle, notably the N'Dama – a West African Bos taurus breed.

•  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.
  • These microbes are squirted into the skin of the animal as the fly feeds and invades the bloodstream, causing the severe and sometimes fatal disease Nagana or African Animal Trypanosomiasis.
  • Most livestock is susceptible to this disease including cattle, sheep, goats, pigs, and horses.
