Abstract: The aim of the present study was to evaluate the impact of Trypanosoma evansi infection on the blood profile of Tunisian dromedary camels. Serological, haematological and biochemical analysis were performed on blood samples collected from 220 dromedary camels (Camelus dromedarius). Giemsa-stained blood smears were used to establish a differential leucocyte count. Others haematological parameters were measured on whole blood collected in EDTA tubes. Sera were used both to perform CATT and to measure some biochemical parameters. More than half of samples (62.7%) were seropositive for trypanosomiasis infection. The comparison of haematological profiles between infected and non-infected camels revealed the presence of a microcytic hypochromic anaemia, neutrophilia, monocytosis and eosinophilia. The biochemical profile of the infected animals showed liver dysfunction (decreased urea and total proteins) and hypoferremia, the last abnormality may lead to microcytic anaemia. Results of the present study revealed that T. evansi was highly prevalent in Tunisian dromedary camels and may induce severe biological disorders. Haemato-biochemical parameters, markedly affected by T. evansi, may be used as biomarkers for the control of this infection in camels.

Key words: Biochemical parameters, Haematological parameters, Trypanosoma evansi, dromedary camel, blood profile, Tunisia
