Incidence of blood parasites of sheep at Alexandria province [electronic reource].

Includes references.

This study was conducted in Alexandria province in Rural areas on 381 sheep of different ages distributed in four different regions (Amryia, Borg EI-Arab, Bangar EISokkar and Abis). In addition to the routine parasitological examination of Gimsa stained blood film which revealed 20.9% of B. ovis infection, two serological techniques were applied. The first was the indirect fluorescent antibody test (IFA) which revealed an incidence of 82.1% positive cases throughout the total screened sheep confirming the above mentioned routine parasitological Giemsa stained blood films. The second seriological test was the enzyme linked immunosorbent assay (ELISA) which revealed 86.8% positive cases. The study revealed that the peak of incidence of B.ovis in sheep was achieved in summer (87.5 and 90.6) by using IFAT and ELISA tests. From the obtained data, it was clear that the ELISA was more sensitive than both IFA and blood film examination.
