The number of endoparasite eggs in different parts of the sheep intestinal tracte

Abstract

The presence of different parasites (Nematodes) in domestic and wild animals may leads to health and economic issues. The nematode control in animals represents the first step in the fight against their unwanted impact. The choice of appropriate anthelmintic will depend on the type of pre-used preparations and time applications as well as the development of resistance to anthelmintic. The question that arises is whether an equal number of parasites can be found in each part of the intestinal tract and is it possible to determine the number of adult’s parasites in the host according to the number of the established nematode eggs? In our research we determinate the number of endoparasite eggs in the caecum and the colon in died sheep. We examined the samples of feces taken from the caecum and colon of three dead sheep by the method of flotation and sedimentation, and the total number of eggs was determined by the McMaster egg counting technique. The goal of our work was to determine whether there are differences in the number of eggs in different parts (caecum and colon), as well as whether there is difference in the presence of the found species of parasites? The nematode eggs of Nematodirus filicolis, Chabertia ovina, Trichotrongylus sp. were found in the caecum samples. The mean value of eggs was 800/grams of the feces. In the colonic samples, Chabertia Ovine, Trichotrongylus sp. were found and the mean value of the number of eggs was 300/grams.
