- ‘Tsetse flies that infect cattle with nagana (animal trypanosomosis) have been ‘all but eradicated from Zimbabwe's farming areas’ he says.’
- ‘Further north the scourge of tsetse fly, vector of the disease nagana, limited the use of cattle as draught.’
- ‘Trypanosomiasis, also locally known as nagana, threatens some 50 million cattle in Africa, according to a recent report by FAO.’
- ‘Here's an interesting strategy to control and eradicate sleeping sickness and nagana.’
