With the intention to verify the frequency of intestinal parasites, we have taken the inside digestive system material from three different parts of the intestinal tract while we were doing 135 complete necropsies. The stools were kept in MIF (Formol, iodine and merthiolate mixture) being studied in slides by the direct method. We have found intestinal parasites in 40 cases (29.6%), 11 (27.5%) with two or more kinds of parasites and 29 cases (72.5%) with only one kind of parasite. The most frequent parasites were: S. stercoralis (31,9%), E. hystolytica (23.4%), hook worm (19.1%) and A. lumbricoides (17%). The results are in according with epidemiological research made in this area. Thus, they prove that the parasitological exam made in feces taken during the necroscopy provides further evidence to enrich the anatomo-pathological diagnosis.
