Distribution of Parasites Detected in Stool Samples of Patients in Le Dantec University Hospital of Dakar, Senegal, from 2011 to 2015

To identify the parasites responsible for intestinal parasitic infections diagnosed at Le Dantec University Hospital of Dakar, distribution of parasites detected in stool samples of patients was studied. From 2011 to 2015, 2578 patients were included in the study. A direct examination and Ritchie technique were performed as parasite search techniques. In total, 408 samples were positive showing 440 intestinal parasites; this corresponds to prevalence of 15.8%. Parasites were detected in monoparasitism (85.7%) and multiparasitism (14.3%). The most common species found in monoparasitism were Entamoeba coli (38.9%), E. histolytica/dispar (12.7%), Giardia intestinalis (8%), and Ascaris lumbricoides (7.3%). The most common associations were A. lumbricoides-Trichuris trichiura (3.6%) and E. coli-G. intestinalis (2.7%). Nonhospitalized patients were significantly more affected with 65.4% compared to hospitalized counterparts; and also there were more men (50.7%) than women. With 67.4%, adults were the most affected age group, while the elderly were less affected with only 7% (). This study shows increasing prevalence of intestinal parasitic infections over the years. So health education should be promoted in addition to the already begun mass treatment program. This would help to limit or even halt the spread of these diseases.
