Objective: To evaluate the situation regarding gastrointestinal helminth parasites in ruminants
(cattle, sheep and goats) slaughtered in the abattoir of Shendi, River Nile State, Sudan.
Methods: From September 2015 to October 2016, a total of 687 fecal samples were collected
and analyzed by flotation and sedimentation techniques.
Results: A total of 411 ruminants examined were positive with one or more helminths,
giving 59.8% overall prevalence with intensity of 548.23 eggs per gram feces. A total of 12
gastrointestinal helminth parasite genera were identified, including 2 trematodes (Fasciola
spp. and Paramphistomum spp.); 7 nematodes (Haemonchus spp., Strongyloides spp.,
Trichostrongylus sp., Ostertagia sp., Ascaris spp., Nematodirus spp., and Dictyocaulus sp.);
and 3 cestodes (Moniezia sp., Taenia spp., and Dipylidium sp.). Prevalence of Taenia spp.
infection was the highest, whereas Trichostrongylus sp. and Dictyocaulus sp. infections had the
lowest prevalences. Adult ruminants had higher infection prevalence than the younger ones, but
this difference was not statistically significant (P > 0.05). On the other hand, male ruminants
had significantly higher infection prevalence than the females (P < 0.05). Helminth prevalence
was significantly higher during the rainy season than the dry season. The highest mean egg
outputs were recorded for the young and the female ruminants. Likewise, the mean egg output
of helminth was higher during the dry than the rainy season, with a significant difference (P <
0.05).
Conclusions: These results encourage implementation of effective preventive and control
measures directed against the parasites of ruminants throughout the country.
