New insights in the interactions between African trypanosomes and tsetse flies

✯ Tsetse fly Glossina sp., a blood- sucking parasitic fly of tropical Africa. The fly pierces the skin of its host with the sharp probo- scis at lower right. The tsetse fly transmits Trypanosoma protozoa, of which T. gambiense & T. rhodesiense cause sleeping sickness in humans. Both male & female flies are bloodsuckers. Their habitat is varied, ranging from forest to river banks to savanna.✯

Tsetse flies are biological vectors of trypanosomes meaning that tsetse, in the process of feeding, acquire and then transmit small, single-celled organisms called trypanosomes from infected vertebrate hosts to uninfected animals. Some tsetse transmitted trypanosome species cause trypanosomiasis, an infectious disease. In humans, tsetse transmitted trypanosomiasis is called sleeping sickness.

A close-up of a Tsetse fly Though roughly similar to a housefly in appearance, tsetse flies come equipped with a large proboscis, which they use to feed on the blood of large vertebrates. (Yes, that includes humans).

The tsetse fly

Tse Tse flies infect people and animals with the deadly Sleeping sickness (African trypanosomiasis). About people die annually of the disease, according to WHO estimates from

TseTse Fly  Another carrier of the deadly sleeping sickness, the TseTse fly feeds on the blood of vertebrates. The spread the disease, trypanosomiases in humans, by biting their victim and passing it through their mouth parts. Living in Africa, the death toll is that much more immense killing 250-300 thousand victims per year.

African trypanosomiasis or sleeping sickness is a parasitic disease caused by the protozoa Trypanosoma brucei, transmitted by the bite of a tsetse fly.

Scientists believe they have found a way to beat sleeping sickness using a bacterium against the tsetse fly host that spreads the disease to humans.    In the same way that we have friendly bacteria in our intestines, the tsetse fly harbours bacteria in its midgut, muscle and salivary glands.

Which disease does tsetse fly transmit? Sleeping sickness! There are 23 species of tsetse flies, that inhabit much of mid-continental Africa between the Sahara and the Kalahari deserts. The tsetse fly serves as both a host and vector for the trypanosome parasites

Researchers have sequenced the tsetse fly genome, which could lead to ways to reduce or end the scourge of African sleeping sickness in sub-Saharan Africa.
