Various species of Trypanosoma parasites are known to infect several wild and domestic animals worldwide. A 7-year-old Holstein cow from Baneh, Kurdistan province, was examined by a private veterinarian due to anorexia and depression. Physical examination revealed fever, enlarged subscapular lymph node, and pale mucosa. Blood samples were taken for hemato-logical, parasitological, and PCR examination. The large Trypanosoma spp. was microscopically observed in a stained blood smear. Decreased red blood cells (RBCs) count, packed cell volume and hemoglobin concentration were observed through complete blood cell count. Nucleated RBCs were also found in this case. Species-specific PCR assay confirmed T. theileri infection. Treatment was performed subcutaneously with diminazene aceturate. The clinical signs were improved after two days. Two-month follow-up showed no recurrence. In conclusion, T. theileri is characterized by anemia and pyrexia in a cow. To our knowledge, the present case report describes the first molecular evidence of T. theileri in Kurdistan, West of Iran.
