Ocorrência de parasitas intestinais na população residente no distrito de Jangamo, Inhambane

Abstract

The internship was carried out in the Department of Microbiology of the Faculty of Medicine, in Parasitology laboratory, and aimed to learn the techniques used in the laboratory for the identification of intestinal parasites, estimate the frequency of intestinal parasites and identify the most common etiological agents. The internship was carried out in four phases. The first phase was biosafety training laboratory, technical adaptation to the laboratory that occurred in a period from June to August 2022. The second phase involved processing, analyzing, recording and interpreting results of the fecal samples made available by the Parasitology laboratory from September to November 2022. The third phase involved presenting the results at the internship site, and data processing in the period from November to February 2023. And the fourth phase was preparation and delivery of the final report between February and June 2024. The motivation for the internship lies in the desire to consolidate theoretical and practical knowledge about the microbiological processes involved in diagnosis, as well as acquiring technical skills in diagnosis. During the internship, in the parasitology sector, fecal samples (n=259) were processed for identification of intestinal parasites, using the Ritchie method, and associations were observed between results obtained with demographic variables: sex, age, and occupation. The study revealed that part of the samples presented intestinal parasites (n = 99) 38.22%. With a frequency of 38.22% and were identified, in descending order: Ancylostoma duodenale (8.5%), Entamoeba coli (6.2%), Entamoeba histolytica (4.2%), Ascaris lumbricoides (1.2%), Giardia lamblia (0.8%), Schistosoma mansoni (0.4%). At the end of the internship, it was concluded that the identification of intestinal parasites using the Ritchie method is of great importance, as it allows assistance to the clinician in their decision-making, in order to improve the health of the population.
