Methods: four exiperment was conducted on mice, use human serum and camel serum as control and inoculated into experimental mice and determine the parasitemia on each group. Results: In mice which injected with human serum with parasite; the parsitemia reduced and death occurs in last days, contrast to control group in which the parasitemia raised. Conclusion: the human serum can be as inhibitor factor which that destructed the parasite.enTrypanosoma evansiThesis
