| TRYPANOSOMIASIS
|
Cattle, Sheep and Goat | Spread by the blood sucking Tse-tse fly which sucks blood from an infected animal and transmit the pathogen to healthy animal. | Rise in body temperature, dullness in appearance, constant sleeping. | Clearing of bush around farm in order to remove the fly’s habitat, spraying with insecticides to kill vector, treatment with drugs such as trypanosomide and antimosan. |
