The results of the study and a significant effect for the lifetime of sheep on the incidence of the parasite at a level (P < 0.05) as the highest infection rate at the age group (7 months and below) and by (66.67 %) than it is in the age group (greater than 7 months) as it was (33.33 %).

The results also show there is no significant difference at the level of probability (P < 0.05) between the incidence of males, which amounted to (48.16 %) and females that were (48.14 %), although there are differences calculation.
