The investigation of intestinal parasites in two primary schools in different social-economic districts of the city of Yozgat, Turkey

The aim of this study was to determine the incidence of intestinal parasites among children in two primary schools in different social-economic districts in the central region of Yozgat and to educate the children about parasitic diseases. During the study, cellophane tape preparations and stool samples that had been prepared using direct mounting methods were examined. In addition the students were informed about intestinal parasites. Parasitic infection was observed in 128 (34.9%) out of 367 students and the highest rate of 16.1% was that of Entamoeba coli. The rate of Giardia intestinalis, Enterobius vermicularis, Hymenolepis nana, Entamoeba histolytica/dispar, Taenia saginata, Ascaris lumbricoides and Trichuris trichiura were found to be 15.5%, 8.4%, 2.2%, 1.6%, 1.6%, 1.6% and 0.5%, respectively. In cases with parasitosis, one species of parasite was found in 68.0%, 2 species in 27.3% and 3 species in 4.7%. Thus, intestinal parasites are important among primary school children in Yozgat and it seems that there is a relationship between socio-economic conditions and the rate of intestinal parasites.
