Abstract
Fasciola spp is one of the liver bile ducts and gallbladder Trematodes in Ruminants. In the life cycle of the worm, snails are intermediate hosts and parasitic infection is happened by eating aquatic vegetables contaminated with Metacercaria. Humans also can be infected with this worm. Thus, Finding the contaminated villages where high infection in animals is reported, can help to control diseases. The aim of this study is to investigate the prevalence of Fascioliasis in Ruminants in 2013 in Dasht Room area, a rural district in Yasuj prevalence. This cross - sectional study, a total of 600 stool samples from Ruminants, including sheep, goat and cattle were collected from six villages in Dasht Room region. The stool samples were transported to the Parasitology laboratory and tested by standard Acid - Ether precipitation method (Thelman method). Sediments were studied with an optical microscope at magnifications of ×10. 174 out of 600 stool samples (29%) were positive for Fasciola spp eggs, including 63 sheep (26/03%), 40 goats (23/3%) and 71 cattle (37/9%), respectively. Significant differences between the infection rates of live stocks were not observed in spring and summer season. The most contamination was observed in cattle and the least in goat. Statistically significant difference was observed between them in summer season (P <0/05). Considering to high contamination in the present study (29%), Dasht Room County is a high risk area for Fasciolosis in Ruminants.

Liver flukes (Fasciola hepatica and Fasciola gigantica; Trematoda: Fasciolidae) are flatworm helminths which cause the disease Fasciolosis in Ruminants and humans [1]
The aim of this study is to investigate the prevalence of Fasciola hepatica and Fasciola gigantica infection in ruminants in 2013 in Dasht Room area, a rural district in Yasuj
Previous studies and this study in Iran and other country it appears that the peak of infection is in the spring and summer growing season and abundance of aquatic plants and associated spring cattle and pasture, there is the issue of the season with this parasite struggle It is important [21]
Summary
Liver flukes (Fasciola hepatica and Fasciola gigantica; Trematoda: Fasciolidae) are flatworm helminths which cause the disease Fasciolosis in Ruminants and humans [1]. Fasciola spp completed its entire life cycle in two host cattle, a definitive host, and the snail, an intermediate host, while the human is an accidental host, which causes disease mostly in ruminants, especially in cattle, buffaloes, sheep and goats.
