Asses Risk Factors Associated with Ovine Fasciolosis, Identification Fasciola and Snail Species in Debre Birhan District, North Shawo Zone, and Amhara Region Central Ethiopia - Abstract
A cross-sectional study design was conducted; starting from December to April 2013 for five months in Debre Birhan districts, North Showa zone, Amhara Region Central Ethiopia, to assess the risk factors associated with infestation of the disease and Prevalence of ovine Fasciolosis.

Prevalence of ovine Fasciolosis was 51.2% and 63.4% found by faecal and postmortem examination respectively. The overall prevalence of snail species in different habitats was that 42.7% in swamp grazing area, 36.4% in water bodies and 20.9% in muddy area. Lymnaea truncatula species were widespread than Lymnaea natalensis species in Debre Birhan districts because of Lymnaea truncatula species prefers highland agro-ecological.
