Abstract
A cross sectional study was conducted to determine prevalence, assess risk factors associated
with fasciolosis and evaluate economic los'>e'> in f()ur selected areas or Tigray Regional State.
during September 2007 to May 2()()~ A total of 1736 domestic ruminants comprising of 1015
cattle, 526 sheep, 167 goats and 28 camel were subjected to coprological investigation and 236
slaugrltered animals were included for post mortem survey. Based on coprological investigation
the ovt-;-ull prevalence uf fasciolo~is was 25.3%" 35.7%, II A'Yo an':l 3.6% in cattle, sheep, goats
and camels, respectively. In the slaughterhouses survey the prevalence of fasciolosis was 33.1 %.
37.2%, and 17.6% in cattle, sheep and goats. respectively. I ligh prevalence was recorded in sheep
(37.2%) and lowest in goats (17.6%). Statistical significant differences was observed in
prevalence among the species (p<0.05) using coproscopy. Fasciola hepatica was dominant in the
highlands while the dominant species in the midland and lowland was F gigantica Differences
in agroecology, season, body condition and age \vere shown to have associations with prevalence
while no significant association was obse[\·ed between sexes of animals. Species of animals.
season, age and agro-ecology were knov.n to be among important risk factors associated with
fasciolosis. The direct and indirect economic loss incurred due to fasciolosis in the study area \\as
estimated to be 268,536.21 Ethiopian Birr. Out of the total incurred losses, 86.3% \vas in cattle.
The present study revealed that infection of domestic ruminants by Fasciola species 'Aas
attributed by the presence of favorable em·ironment for the abundance of intermediate host and
the parasite, hence requiring immediate strategic intervention against the disease.
