BACKGROUND: Trypanosomosis is a blood parasitic disease with veterinary and cosmopolitan importance due to Trypanosoma evansi (Kinetoplastida: Trypanosomatidae) type A in camels, cattle, buffaloes, and equine and type B in camels. OBJECTIVES: We conducted the present study to discriminate Trypanosoma evansi type A and B infection in one-humped camels (Camelus dromedarius) in Sistan-va-Baluchestan Province, south eastern Iran. METHODS: A total number of 369 blood samples were randomly taken from jugular vein of the examined one-humped camels from different parts of the region. Genomic DNA was extracted and polymerase chain reaction (PCR) was performed to amplify 205bp-fragment-length and 436bp-fragment-length of RoTat 1.2 VSG gene (T. evansi type A) and Minicircle gene (T. evansi type B), respectively. RESULTS: Molecular findings revealed that all the infected camels were affected by T. evansi type A. CONCLUSIONS: Based on the results of the current study, we could conclude that the cause of infection in the examined camels of the region, like other parts of the world, was T. evansi type A.
