This study was conducted to investigate the hematological effect of hard ticks Hyalommma  anatolicum, feeding on rabbit blood by measuring some hematological tests (Hemoglobin concentration Hb, Packed cell volume PCV, Red and White blood cell counts). 20 local rabbits were used housing in special cages under slandered environmental conditions, rabbits were divided into 2 groups each one containing 10, first group was infected with an adult hard tick Hyalommma anatolicum, the second is control, 3 months after infection, blood was withdrawn from the groups and some tests were performed (as mentioned above).T-test analysis was use in this experiment . Results showed that Hemoglobin, packed cell volume, and red blood cells were significantly decreased (6.1930, 2.4510 and 22.2200) respectively at (p˃0.05) in the tick-infected group, the decrease was evident when comparing with control group (12.9910, 6.9310 and 42.1090) respectively. On the other hand, the number of leukocytes was significantly higher (17.4590) at (p˃0.05) of infected animals when compared with healthy animals (10.5390). This indicate that ticks, which feed on the animals for a long time cause a defect in the functions of the body, especially blood, where there was a clear anemia in the infected rabbits due to (blood absorption and toxin excreted to the blood stream), this acute decrease of blood led to the occurrence of large infections in the body and which was clear through the increasing of WBC counts values, this confirms that there is a negative effect on the blood of ticks parasitize on animals.
