Twenty seven blood samples were received at the Clinical pathology Laboratory of Veterinary Teaching Hospital, University of Mosul, from fifteen cows (2-5 years old) and twelve calves (10-12 months old) of different farms located around Mosul city. Clinical signs of the infected animals revealed fever, progressive weight loss, anemia, and frequent recumbent position. Identification of trypanosome species were based on their motility using morphological differentiation on Giemsa or Leishman stained that showed trypomastigot which can be classified according to the biometrical data into T. brucei and T. congolense.
