Changes in the levels of some serum enzymes in dromedary camels infected with Trypanosoma evansi

The serum levels of sorbitol dehydrogenase, alkaline phosphatase, glutamic pyruvic transaminase and glutamic oxaloacetic transaminase in healthy male dromedary camels were determined. The camels were then infected with Trypanosoma evansi and the same enzymes determined at intervals, both during the period of infection and after treatment with the trypanocidal drugs suramin and quinapyramine sulphate. Increases in the serum levels of sorbitol dehydrogenase, glutamic pyruvic transaminase and glutamic oxaloacetic transaminase were recorded, together with a decrease in the serum level of alkaline phosphatase during the period of patent parasitaemia. The levels of the enzymes returned to normal after drug treatment.
