Prevalence of Intestinal Parasitic Infection Among Inhabitants and Tribes of Chelgerd, Iran, 2008-2009.

INTRODUCTION

Although a notable development in treating and controlling of parasitic infections in recent years has occurred but, these infections are still counted as important problems in many countries.

AIM: The aim of this study is to determine the prevalence of intestinal parasitic infections in the inhabitant and tribe populations who were referred to central health care of Chelgerd, Iran.

MATERIALS AND

METHODS

This descriptive cross-sectional study was carried out from April 2008 to October 2009 in Chelgerd, Iran. A total of 655 samples of feces from inhabitants and tribes were collected and each sample was examined by Direct smear, formol- ethyl acetate concentration and Trichorom staining.

RESULTS

Out of 655 stool samples, 367(56%) patients revealed at least one intestinal parasite (pathogenic /non-pathogenic protozoa/helminth), 233(67.7%) in tribes and 134(43%) in inhabitants. There was significant difference between infected inhabitants and infected tribes (p=0.001). Although the intestinal parasitic infections were more in female than male it was not statistically significant (p=0.52). There was no significant difference in various age groups. Common intestinal parasitic infections which were detected in both the populations were Giardia intestinalis (28.2%) and Blastocystis hominis (27.5%).

CONCLUSIONS

We found that the prevalence of intestinal parasitic infections was higher in the tribe than inhabitant populations. Prevalence of intestinal protozoa infections was much higher than the helminthic infections. These findings reflect poor sanitary conditions in this region. They should be educated and provided better facilities to get rid of intestinal parasitic infections.
