    abstract = {Cross sectional study was conducted on indigenous sheep and goats slaughtered 
  at Addis Ababa Abattoir. A total of 427 animals were sampled to determine the 
  prevalence of helminthes parasites by coprology and postmortem examination of 
  the same animals with emphasis on liver lesion and fasciolosis. Simple direct 
  smear and sedimentation technique were used to examine the eggs of gastrointestinal 
  parasites and Fasciola. The liver of the target animal was thoroughly inspected 
  by visualization, palpation and incision for the identification and exposing 
  of pathological lesion and parasites. The overall prevalence of helminthes parasites 
  of small ruminants was 21.1% (goats) and 39.5% (sheep). There was statistically 
  significant (p<0.05) difference in the overall prevalence of the parasites 
  where higher prevalence was recorded in sheep than in goats. Of a total of 427 
  animals sampled, 163 (38.2%) livers were condemned due to sever pathological 
  lesions. In general 8.8% of liver from goats and 29.3% of liver of sheep had 
  one or more different types of lesion. The major lesions of liver on both animal 
  species encountered during postmartem examination were white spot (4.4%), calcification 
  (3.5%), discoloration (2.6%) and narcotization (2.3%). The study has indicated 
  that helminthes parasites are highly prevalent in the study area which insists 
  further epidemiological study to assess the significant effect of risk factor 
  on the prevalence of gastrointestinal parasites.}
