Abstract

Objective: The aim of the study was to evaluate the changes which have occurred in the prevalence of intestinal parasites in Syria between 2006 -2011.

Methods: This study was carried on in seven cities in Syria on primary school students in the years 2006-2011.

The number of student’s fecal samples examined was 4152 from seven Syrian areas included: Damascus and its countryside, Idlib and countryside, countryside of Daraa, Kalamoon, Hama and countryside, Countryside of Alraqa and countryside of Tartous.

Results: The results showed that there were 1290 stool samples with positive parasites (31.07%), 481 samples of them have pathogenic human’s parasites (37.28%). The pathogenic parasites which have been seen in this study according to their prevalence rate were as follows: Protozoa: Giardia lamblia 8.48%, Chilmastix mesnili 1.06%, Entamoeba histolytica 0.14%. Helminthes: Hymenolepis nana 1.20%, Enterobius vermicularis 0.43%, Strongyloides stercoralis 0.17%, Trichuris trichuria 0.05%, and Ascaris 0.05%. Where the nonpathogenic parasite which have been seen in this study according to their prevalence rate were as follows: Blastocystis hominis 13.15%, Entamoeba coli 5.73% and Iodamoeba butschili 0.60%.

Conclusions: It was observed that Giardia lamblia and Hymenolepis nana which regarded as pathogenic parasites were the most prevalent in Syria, but the other types of parasites were very rare.
