Abstract

Haematological changes associated with Trypanosoma congolense on experimentally infected
donkeys were investigated. Four donkeys were infected intravenously with 1 x 106 trypanosomes
per ml of blood obtained from donor mice and monitored for changes in the blood picture over a
period of 28 days. There was a rapid significant (P<0.05) decrease in the Pack Cell Volume
(PCV) value of the infected donkeys from initial mean of (27.29±0.73 %) pre-infection to
(25.39±0.46 %) post-infection. Also, a significant (P<0.05) decrease in the mean value of the
haemoglobin concentration from (9.08±0.24 g/dl) pre infection to (8.43±0.16 g/dl) post infection
was observed. No significant difference (P<0.05) were observed in the Mean Corpuscular
Volume (MCV) and Mean Corpuscular haemoglobin concentration (MCHC). A significant
(P<0.05) increase in white blood cell count was observed with mean values ranging from
(9.16±0.26 ?l) pre infection to (12.33±0.39 ?l) post infection. It can be concluded that
T.congolense produces significant changes in the haematological parameters in infected donkeys.
