Effects of Theileria lestoquardi Infection on Haematological and Biochemical Parameters in Experimentally Infected Desert Ewes

Studied in ten Sudanese desert ewes together with 10 clinically healthy ewes. The obtained results showed a significant (P < 0.05) decrease in haemoglobin, packed cell volume and white blood cells counts compared to the control group. The decrease in Hb concentrations and PCV % was observed 7-10 weeks after tick application whereas ; the decrease in WBCs occurred at week 5 and week 6 after tick application. There was also a significant decrease (P < 0.05) in serum total proteins, and serum globulins values of the infected group at week 3- week7 after tick application. A significant increase (P < 0.05) in serum urea and serum creatinine values in the infected group was noticed during the first 7-8 weeks in the infected group compared to the control one’s.
