The aim of this study to mentioned the effect of pregnancy on blood parasitemia of some protozoalinfections and total, differential of white blood cells counts from 22 Awassi ewes 3-3.5 years agenaturally infected by Theileria hirci and Anaplasma marginale.Our results showed that there was a positive relationship between the development of pregnancy stagesand the blood parasitemia till reach the highest levels during the last months (fourth and fifth) ofpregnancy of Theileria hirci and Anaplasma marginale 3±0.06%, 2.29±1% and 0.77±0.15%,1.09±0.87% respectively.The total white blood cells count decrease in the first month of pregnancy (5.780±0.54×10³cell/mm³), while increased during the others which reach the highest level in the fourth month ofpregnancy (10.000±0.46×10³ cell/mm³) and then decreased to the lowest level during the lactationmonth (4.920±0.82×10³ cell/mm³) comparison to control group (6.550±0.71×10³ cell/mm³). Neutrophilswere increased during the three months which reach the maximum level during the third month(40±1.98%) and then decreased to the lowest level during the lactation month (25.36±3.46%)comparison to control group (31.46±3.26%). On the other hand, lymphocytes were decreased during thefirst three months to reach the lowest level in the first month (46.8±8.42%) and then return to increasedduring the last tow months of pregnancy to reach to high level in the lactation period (70.79±4.13%)comparison to control group (62.76±3.64%). Monocytes were increased during all pregnancy stages andreach the maximum level in second month (7.4±0.75%) comparison to control group (3.98±0.44%).Same results showed eosinophils except they decreased sharply during the second month (0.8±0.72%)from maximum level in the first month (14.4±4.96%) and slightly decreased during lactation period(1.93±0.56%). Our results showed that the pregnancy stages have a direct effect on blood parasitemia,total and differential counts of white blood cell.
