Bottom Line: The results clearly showed the presence of B. (Theileria) equi DNA in 30 of 31 blood samples (96.77%), but the microscopic examination revealed the 3 of 31 positive Babesia like organisms in the red blood cells (9.67%).The obtained results demonstrated the presence of hidden B. (Theileria) equi infection in horses with previous habitance in Kurdistan Province of Iran.Therefore, hidden infection might be considered as a health threatening and limiting factor in animals used in therapeutic antisera research and production centers.

ABSTRACT

Background: Equine piroplasmosis (EP) is the cause of persistent tick-borne infection with no symptoms, but the most important problem of EP is due to the persistent carrier state. Carrier animals to Babesia (Theileria) equi (Laveran 1901) and B. caballi (Nuttall, 1910) infestation could be identified by extremely sensitive PCR-based method. The purpose of this study was to identify the causative agents of equine piroplasmosis based on molecular and microscopic assays in equids from Kurdistan Province, Iran.

Methods: Thirty one horse and mule blood samples were used with history of living in Kurdistan Province of Iran. The blood specimens were utilized for T. equi and B. caballi DNA identification by PCR and Giemsa stained smears for microscopic observation.

Results: The results clearly showed the presence of B. (Theileria) equi DNA in 30 of 31 blood samples (96.77%), but the microscopic examination revealed the 3 of 31 positive Babesia like organisms in the red blood cells (9.67%).

Conclusion: The obtained results demonstrated the presence of hidden B. (Theileria) equi infection in horses with previous habitance in Kurdistan Province of Iran. The carrier animals became a main source of infection and can transmit the disease. Therefore, hidden infection might be considered as a health threatening and limiting factor in animals used in therapeutic antisera research and production centers.

Mentions: The microscopic examination for 31 Giemsa-stained blood smears revealed the three positive samples (red blood cells that are infected with Babesia / Theileria parasites) out of 31 samples (9.67%) (Fig. 1).
