The prevalence of intestinal protozoa in wild and domestic pigs.
We examined faecal samples from 842 domestic and 91 wild pigs in order to record the prevalence of intestinal protozoa. We used staining of faecal smears by Noller-Westphal-Gönnert method, cultivation in modified LES broth and microscopical examination of native preparations using small magnification (for detection of Balantidium coli). Moreover, the faeces from wild pigs were examined by flotation in Sheather's sugar solution for detection of coccidia. We found 8 coccidian species in the wild pigs. Except sucking piglets, high prevalence of B. coli, Entamoeba polecki, lodamoeba sp. and Tritrichomonas suis was noticed in all categories of animals. On the other hand, only sporadic occurrence of Chilomastix sp. was recorded. The intensity of infections by different protozoa was variable in all categories of animals. It is not sure whether Chilomastix sp. and Iodamoeba sp. are identical with the species known from the intestine of humans and that is why their epidemiological importance is not clear.
