ABSTRACT
BACKGROUND:
The prevalence of intestinal parasitosis is very different according to countries. Therefore, it is always interesting to update the data in Tunisia to better direct control measures.AIM:
The objectives of this survey were to estimate the prevalence of intestinal parasitosis in the region of Tunis, to study their evolution and to establish various combinations of intestinal protozoa.METHODS:
This is a retrospective study carried out over a period of 17 years from 1996 at 2012 and which involved 20033 individuals. Each subject had one or more stool examination which included a direct microscopic examination and a concentration by modified Ritchie technique.RESULTS:
The prevalence of intestinal parasitosis was 12.55%. Entamoeba histolytica/dispar and Giardia intestinalis accounted respectively a prevalence of 0.51% and 1.48%. Hymenolepis nana was the most predominant helminth with a prevalence rate of 0.53%, followed by Enterobius vermicularis (0.21%). Two cases of Hookworms and seven cases of Strongyloides stercoralis were diagnosed. Polyparasitism concerned 16.59% of infected individuals. Significant combinations occured mainly for amoeba in particular Entamoeba histolytica/dispar and Entamoeba coli (r=0.232).CONCLUSION:
Our study confirms the decrease of the prevalence of giardiasis and amebiasis, whereas helminthiases with direct transmission remain frequent.
