| Abstract: | The therapeutic activity of a combination of difluoromethylornithine (DFMO) with diminazene aceturate was investigated in mongrel dogs experimentally infected with Trypanosoma congolense. The criteria used in the assessment of the trypanocidal effect of the therapy include the examination of the blood for parasites, as well as clinical and haematological changes at intervals following treatment. Diminazene aceturate and DFMO alone and in combination produced intermittent aparasitaemia in the dogs. Although relapse infection occurred with all three treatment regimes, the drug combination gave the best result. The packed red cell volume, haemoglobin concentrations and red blood cell values decreased significantly following parasite inoculation but increased after treatment. The total leucocyte counts decreased in all the infected dogs but improved with treatment, and the differential leucocyte counts indicated neutropenia in all the infected animals prior to treatment. |
