PROTOZOAN DISEASE | ANIMAL AFFECTED | MODE OF TRANSMISSION | SYMPTOMS | CONTROL/PREVENTION |
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. |
COCCIDIOSIS Eimera sp | Domestic fowl, duck, goose, turkey, guinea fowl and rabbit | It is spread through faeces, litter, feed, water and contaminated soils. | Dropping wings, loss of appetite, blood stained diarrhoea, emaciation, high mortality, loss of hair/ acopecia (in rabbit) | Proper sanitation, avoid wet litters and feed, change of litter used and general disinfection, use suitable drugs such as amprolium and nitrofurazone in water, treat with coccidiostats. |
RED WATER FEVER (PIROPLASMOSIS) Babesia sp | Cattle, Sheep, Goat and Pig | It is transmitted through the bite of vector called Blue tick. | Rise in body temperature, loss of appetite, diarrhoea, pale red colour of urine, emaciation and death. | Spray with insecticides to kill vector of disease (blue tick), injection of drugs such as Trypan Blue, Babesan or Phenamidine. |
