Scientists have sequenced and annotated
the genome of sleeping sickness disease vectors. The study which has
been published this month in Science, describes the genetic code for a representative Savannah species of tsetse fly (Glossina morsitans),
vectors of protozoan parasites, trypanosomes that cause sleeping
sickness in humans and nagana in animals mainly in sub-Saharan Africa.
It is estimated that 70 million people are at risk of infection and
