Abstract
Fascioliasis is the disease caused by liver fluke (F. hepatica and F. gigantic) - Sheep and cattle are the most commonly affected, and sheep are more susceptible to the disease than cattle. Horses, deer, goats and even camels may also be infected by liver fluke; humans are also occasionally infected. The present study was devoted to throw some lights on epidemiology of fascioliasis in some governorate in the Arab Republic of Egypt. To achieve this goal, coprological examination were carried out to compare between the prevalence of fascioliasis during the four seasons in Cairo, Sharkia, Monofia, Garbia and Sowhag governorates.The present study approach fasciola problem from the aspect of field contamination by eggs that were shed from infected sheep, as the basic point in continuation of the parasitic life cycle in the field. Coprological examination was carried out on faecal samples collected from more than 1000 sheep for detection of Fasciola egg. More over for detection of fasciola worms the post mortem examination were carried out in Cairo, Monofia and Al-Garbia abattoirs and calculate the condemnation liver which selected mainly duo to fasciola infection. In the post mortem examination, the present study revealed, the prevalence rate of sheep’s liver condemnation in different abattoir. The absence of fasciolicidal drug; able to clear the treated animals completely from infection resulted from the fact that the infected animals shed Fasciola spp.
