Clinical and cytological characteristics and prognostic implications on sheep and goat Theileria infection in north of Iran.

ABSTRACT

The present research was carried out during 3 months from early June through late August, in northern zones of Iran. In addition, the present study was performed on 300 sheep and goats, in which 50 specimens were isolated based on clinical signs, blood smears and lymph node puncture. The results indicated clinical signs of theileriosis in sheep (with more prominent signs) and goats were diagnosable. The reliable clinical signs in sheep and goats included fever, tachycardia, cough, increased respiratory rate, mucosal pallor, anorexia, ruminal hypomotility and lymph node enlargement. Furthermore, the frequency of cough, abnormal pulmonary sounds, anorexia and ruminal hypomotility were significantly more in sheep than goats (P < 0.05).
