Abstract:
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.
Insights
Necropsies revealed intestinal parasites in 29.6% of cases, with Strongyloides stercoralis and Entamoeba hystolytica being most common. Fecal exams during necropsy aid anatomical pathology diagnoses.
Area of Science:
- Veterinary Pathology
- Parasitology
- Public Health
Context:
- Intestinal parasite prevalence impacts animal health and can pose zoonotic risks.
- Necropsy provides a unique opportunity for in-situ sampling of the digestive tract.
- Accurate diagnosis of parasitic infections is crucial for effective treatment and control.
Purpose:
- To determine the frequency of intestinal parasites in a necropsy cohort.
- To identify the most prevalent intestinal parasite species.
- To evaluate the utility of necropsy-derived fecal samples for parasitological diagnosis.
Summary:
- A study involving 135 necropsies examined intestinal contents from three distinct tract regions.
- Fecal samples were preserved using MIF (Formol, iodine, merthiolate mixture) and analyzed via direct microscopy.
- Intestinal parasites were detected in 40 cases (29.6%), with single infections in 72.5% and multiple in 27.5%.
Impact:
- Strongyloides stercoralis (31.9%), Entamoeba hystolytica (23.4%), hookworm (19.1%), and Ascaris lumbricoides (17%) were the most frequent findings.
- Results align with existing epidemiological data for the region.
- Parasitological examination of feces collected during necropsy enhances anatomo-pathological diagnostic capabilities.
