Abstract
The present study was attempted to determine the prevalence rates of fascioliasis
among farm animals and man, by using coprological and serological techniques
as well as to compare between the excretory / secretory (E/S) and crude Fascioliasis, caused by Fasciola hepatica and Fasciola
gigantica ,commonly known, as liver flukes, is a disease of herbivorous
animals. It has a worldwide distribution in a large variety of grass-grazing
animals as sheep, goats, cattle, buffaloes, horses and rabbits. In Egypt,
donkeys and camels as well, are hosts for Fasciola gigantica. Fascioliasis
may occasionally affect man (Haseeb et al., 2002; Sanad and Al-
Megrin, 2005).antigens
in the serological diagnosis by using ELISA technique. Fasciola ova were
demonstrated in fecal samples of farm animals with prevalence rates amounting,
to 18.0% buffalo, 14.0% cattle, 12.0% sheep, 9.0% goat and 0.0% equine. On
the other hand, 5.0% of the examined human were proved to harbour Fasciola
ova. While, in the serological examination, the results by using E/S antigen
amounted to 20.0% buffaloes, 16.0% cattle, 15% sheep, 10% goat and 3.2%
equine, while in human the results was 5%. On the other hand, the results
obtained by using crude antigen amounted to 24% in buffaloes, 21% cattle, 17%
sheep, 12% goat and 5% equine while in human the result was 8%. Also, about
1050 samples from different plants were collected to detect the percentage of
infection of these pknts by encysted metacercariae. The results of examination
were 1% in lettuce end 2% in watercress in Giza Governorate while in El-
Fayoum the result was 3% in watercress. Also, the laboratory examination of the
snails collected from Abu-Rawash indicated that L. cailliaudi is domestic snail
and play a great rok in the transmission cycle of fascioliasis and none of B.
alexandrina and P. acrta plays a role in transmission cycleIn Egypt, Fasciola gigantica used to be the only species
prevailing in domestic animals with considerable veterinary
importance. Recently, it appears that Fasciola hepatica has been
introduced to Egypt, possibly with living cattle and sheep
imported from endemic countries (Allam, 1992).Fascioliasis give rise to important economic losses such as great
expenses with anthelmentics, liver condemnation, production
loss due to mortality, lower production of meat, milk and wool;
reduced weight gain, and impaired fertility (Parr and Gray,
2000; Marques and Scroferneker, 2003). Fascioliasis becomes
a public health disease that markedly affects human welfare in
Egypt (Motawea et al., 2001).Two clinical stages are recognized in fascioliasis. An acute stage
coincides with the larval migration and worm maturation in the
hepatic tissues, and a chronic stage coincides with the
persistence of Fasciola worms in the bile ducts (Haseeb et al., 2002)
Fascioliasis is controlled by a combination of anthelmintic therapy and management measures. These methods are costly
and may lead not only to anthelmintic resistance, but also to un
desirable residues in food or the envfironment (Perez et al.,
2002). Consequently, the control o is one of
important aims in our work.Aim of the work:
The present work is planned to study
(1) The prevalence of fascioliasis in slaughtered animals in sohag
abattoirs.
(2) Histopathological changes due to fascioliasis.
(3) Parasitological examination to fasciola.
