Objective: This investigation was undertaken to evaluate the prevalence of intestinal parasitosis in patient addressed to the hospital of Oran and to identify parasites causing this infection.
Design: The survey was made on 1042 individuals, external and hospitalized, having between one month and 80 years old, addressed te H.U.C. of Oran. For every patient, an analysis of stool sample was done including direct and complementary methods.
Results: The prevalence is about 19,96%. Adultes (71,15%) are more parasited than children (28,84%). The sex ratio is equal to 1. It is essentially Protozoa parasitism with 95,7% and Helminth represent only 4,3%. The intestinal parasites founded are : Blastocystis hominis 47,17% Entamoeba coli 18,95%, Giardia intestinalis 15,32%, Endolimax nana 5,24%, Entamoeba histolytica 4 ,83%, Pseudolimax butschlii 4,43%, Enterobius vermicularis 2,82%, Cryptosporidium sp 0,4%, Ascaris lumbricoides 0,4% and Taenia saginata 0,4%. Statistically, it was no significant to the distribution of parasites species by sex. But according to age, it was significant for Giardia intestinalis which infects more children than adults, for Endolimax nana and Blastocystis hominis with the most infection of adults.
Conclusion: The majority of parasites listed are not pathological. Their epidemiology is linked to faulty hygiene; this is why developing countries are the most concerned.

Abstract: (french)
Objectifs: Cette enquête a été entreprise pour évaluer la prévalence des parasitoses intestinales chez les malades adressés au centre hospitalo-universitaire d'Oran (C.H.U.O.) et pour identifier les parasites à l'origine de ces affections.
Patients et méthodes: L'étude a concerné 1042 sujets, externes et hospitalisés, âgés de quelques jours à 80 ans, adressés au laboratoire de Parasitologie et Mycologie du C.H.U.O. Chaque patient a bénéficié d'une analyse parasitologique complète des selles comprenant un examen direct macroscopique et microscopique ainsi qu'une technique d'enrichissement.
Résultats: La prévalence des parasitoses intestinales est de 19,96%. Selon les groupes d'âges, les adultes parasités représentent 71,15% et les enfants 28,84%. Le sex-ratio des sujets parasités est égal à 1. C'est essentiellement un parasitisme à Protozoaires avec 95,7% alors que les Helminthes ne représentent que 4,3%. Les parasites intestinaux recensés sont : Blastocystis hominis 47,17%, Entamoeba coli 18,95%, Giardia intestinalis 15,32%, Endolimax nana 5,24%, Entamoeba histolytica 4,83%, Pseudolimax butschlii 4,43%, Enterobius vermicularis 2,82%, Cryptosporidium sp 0,4%, Ascaris lumbricoides 0,4% et Taenia saginata 0,4%. Statistiquement, il n'a été observé aucune variation notable des parasites en fonction du sexe des patients tandis qu'en fonction de l'âge l'espèce Giardia intestinalis est plus retrouvée chez les enfants. Par contre, Endolimax nana et Blastocyctis hominis sont plus fréquentes chez les adultes.
Conclusion: La majorité des espèces parasites répertoriées sont peu pathogènes. Leur épidémiologie est très liée à un défaut d'hygiène, ce qui expliquerait que les pays en développement soient les plus concernés.
