Abstract:
A cross sectional study was conducted from July to
September 2015 in El-Dueim slaughterhouse, the White
Nile state, the Sudan, to estimate the prevalence of
Fasciola species and their eggs in the livers and feces of
cattle and to investigate potential risk factors associated
with them. The liver inspection during post-mortem
examination and sedimentation technique were used. The
overall prevalence's of Fasciola species and their eggs were
43.4% (n= 92; 95% CI from 36.73 to 50.07) and 72.6% (n=
92; 95% CI from 66.6 to 78.6), while prevalence by risk
factor category, ranged from 23.6% to 78.0% and from
60.0% to 90.0% respectively. Body condition (x2=45.0, pvalue=
0.001), grazing (x2=5.49, p-value=0.019), and
presence of snail (x2=36.3, p-value=0.001) were associated
with detection of Fasciola in the livers of slaughtered cattle
in the univariate analysis. The same risk factors, excluding
grazing, were also associated with the detection of the eggs
of Fasciola in the feces. Cattle with poor body condition
and in presence of snails were at higher risk of finding the
worm and eggs in their livers and feces in comparison to
the reference category of the same risk factor in the
multivariate analysis. It can be concluded that the liver
flukes and their eggs are prevalent in the White Nile state.
Therefore, the use of and the limnetic by cattle farmers
from is recommended as a prophylactic measure.
