Abstract

The aim of this study to mentioned the effect of pregnancy on blood parasitemia of some protozoal
infections and total, differential of white blood cells counts from 22 Awassi ewes 3-3.5 years age
naturally infected by Theileria hirci and Anaplasma marginale.
Our results showed that there was a positive relationship between the development of pregnancy stages
and the blood parasitemia till reach the highest levels during the last months (fourth and fifth) of
pregnancy 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±0.54×10³
cell/mm³), while increased during the others which reach the highest level in the fourth month of
pregnancy (10.000±0.46×10³ cell/mm³) and then decreased to the lowest level during the lactation
month (4.920±0.82×10³ cell/mm³) comparison to control group (6.550±0.71×10³ cell/mm³). Neutrophils
were 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 the
first three months to reach the lowest level in the first month (46.8±8.42%) and then return to increased
during 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 and
reach 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.
