How Nagana or Animal Trypanosomiasis is carried by tsetse flies .

How Nagana or Animal Trypanosomiasis is carried by tsetse flies . Researchers at the University of Bristol have revealed new details on how the animal disease Nagana is spread by tsetse flies in Africa. When animals are bitten by bloodsucking tsetse flies, they don't just get a painful bite, as the flies may be carrying a cargo of deadly microbes, trypanosomes. These microbes are squirted into the skin of the animal as the fly feeds and invade the bloodstream, causing the severe and sometimes fatal disease Nagana or African Animal Trypanosomiasis. Most livestock are susceptible to this disease including cattle, sheep, goats, pigs and horses. Tsetse flies pick up the microbes when they take blood from an infected animal. The blood is digested inside the gut of the fly, but the trypanosomes need to find their way back to the mouthparts so that they can be passed on to the next animal the fly bites.
