    Abstract:
    BACKGROUND: In order to fight digestive parasitism in Tunisia, a national program of surveillance of non-permanent resident students in Tunisia has been found to detect these parasitosis in this target population. OBJECTIVE: To determine the prevalence of intestinal parasitosis among non-permanent resident students in Tunisia, to identify the different parasitic species founded and to show the interest of this screening. METHODS: During a period of 23 years (1990-2012), 7386 parasitological examinations of stools has been made among students essentially from or had visited tropical Africa, Maghreb and Middle-East, at the laboratory of Parasitology-Mycology at the Rabta Hospital of Tunis. RESULTS: The prevalence of intestinal parasitism found was 34.45% (i.e. 2545 infested students). Among the protozoa that have been isolated in the majority of cases (78.75%), amoebae were most frequently found (86.4%) represented mainly by Entamoeba coli and Endolimax nanus in respectively, 25.62 and 23.33% of parasites isolated; while Entamoeba histolytica/dispar, only pathogenic Amoeba was found in 8.05% of the total of parasites isolated. Regarding helminths, found in 21.25% of parasites isolated, Ankylostome was predominant (34.5%) represented by the species of Necator americanus. A single case of Ancylostom duodenale has been isolated. Among the identified parasite species, 38.7% were known parasitic pathogens for humans. CONCLUSIONS: These results note the interest of the control of the non-permanent resident students in Tunisia. The precocious tracking and treatment of affected subjects permits to avoid the introduction and the dissemination of parasites already rare and virulent strains in our country.
