Abstract: 

Objective: Study on the Prevalence and Pathology of Fasciola in camel of Iran.
Project: Cross-Sectional study.
Animals: Four hundred and study camels slaughtered at industrial abattoir of Mashhad, north west of Iran.
Procedure: The liver of490 native camels slaughtered at Mashhad industrial abattoir were examined for Fasciola between April 20002001. Age and sex of animals were recorded. Pieces as big as 5×5 mm were taken from infected livers and fixed in 10% formalin. After processing, sectioning and staining, pathological changes induced by parasite were studied in the section taken. Then the whole of any infected liver was sliced into 1-3 Cm. The pieces were firmely squized in warm water for removing any parasite from the bile ducts into water. The Fasciola were collected and fixed in 10% formalin. According to morphological features of stained worms and the dimension of 20 unstained adults Fasciola and 20 eggs the species of trematode was identified as F hepatica.
Statistical analysis: Chi-square test.
Results: Our findings revealed that 5.3% of the examined livers harboured Fasciola hepatica. The average number of Fasciola was 10.5 although 75 and 92 Fasciola were collected from two camels. No significant relation was found between age, sex and infection to Fasciola. The main pathological changes induced by liver flukes were: necrosis, fibrosis, infiltration of inflammatory cells, cholangitis and arteriolosclerosis.
Conclusion: This is the first report on the prevalence and pathology of Fasciola of camel in Iran. It was concluded that camel as new host for Fasciola can play a role on the dessimination of liver fluke infection to other herbivoures as well as human beings. Although the mean number of worms per infected animals was low (10.5) but considering the pathogenicity and the pathology of Fasciola and low standard nutrition of local camels, even low infection can be harmfull to the health of animal production.
