A survey of trypanosomosis in Zambian goats using haematocrit centrifuge technique and polymerase chain reaction.

The incidence of trypanosomosis was determined using the haematocrit centrifuge technique (HCT) as well as polymerase chain reaction (PCR) on 120 goat blood spots on filter paper. Both techniques failed to detect a positive reaction, implying that factors such as age, healthy appearance and small sample size notwithstanding, trypanosomosis does not seem to pose a serious threat to goat health in the districts from where the animals originated.
