The aim of the study was to determine the prevalence and evolution of intestinalis parasites in hospital area. For the present investigation, ۲۴۰۱ samples, including ۴۰۳ urines and ۱۹۹۸ stool, were collected. The age of patients ranged from ۲ months to ۸۷ years with a mean of ۲۴.۲۴ ± ۱۸.۵۸ years. Females predominated (۵۱.۱%) with a sex ratio of ۱.۰۴. The average prevalence of parasitic infection was ۱۵.۵۸ %. Throughout the years, it was found that the infectivity rates varied significantly, Chi۲ = ۸۷.۵۲۲ p = ۰.۰۰۰۰. There was no significant variation between sex and parasitic infection, p> ۰.۰۵. Fourteen species of parasites were identified, including ۱۱ in the feces and urine ۳. In stool (n=۱۹۹۸), the prevalence of parasites were as followings: Entamoeba histolytica ۴.۸۰% (۹۶/۱۹۹۸) , followed by Ascaris lumbricoides ۴.۲۰% (۸۴/۱۹۹۸) , Trichomonas intestinalis ۳.۳۵ % (۶۷/۱۹۹۸), Giardia lamblia ۱.۶۵% (۳۳/ ۱۹۹۸), Hymenolepis nana ۰.۷۰% (۱۴/ ۱۹۹۸) Schistosoma mansoni ۰.۶۰% (۱۲/ ۱۹۹۸), ۰.۵۵% Taenia saginata ( ۱۱/۱۹۹۸ ), Strongyloides stercoralis ۰.۲۰% (۴/ ۱۹۹۸), Ancylostoma duodenal , ۰.۱۵ % (۳/۱۹۹۸) and Taenia solium ۰.۰۵ % (۱/ ۱۹۹۸). In urine, the prevalences of parasites were: Schistosoma haematobium was ۱۰.۴۲% (۴۲/ ۴۰۳), followed by Trichomonas vaginalis ۲.۲۳% (۹/۴۰۳), Candida albicans ۰.۷۴ % (۳/۴۰۳). The prevalence evolution of parasitic infections following the years from ۲۰۰۵ to ۲۰۱۰ were respectively ۱۱.۶۱% , ۱۲.۲۶% , ۱۵.۶۲% , ۸.۳۳ %, ۲۰.۰۵ % and ۳۳.۴۵% . In ۲۰۱۰, prevalence of A. lumbricoides was ۷۶.۹۰ % among children aged less than ۱۰ years. Protozoa were the most frequent, but showed no infection mixed together in the same patient. The distribution of these parasitic infections (for patients of Luxembourg Hospital) was increasingly growing in the district of Bamako, despite efforts in the fight against these diseases. This study showed that intestinal parasites are weakly present in hospital in Bamako. The latter could be explained by the effect of mass treatment in the population. But urinary schistosomiasis was still important. Although, endemicity risk of Ascaris lumbricoides and Entamoeba histolytica was considerable.
