Intestinal parasites are important enteric pathogens. Poverty, low quality of food and water supply and poor sanitation systems are the important factors associated with intestinal parasitic infections. These kinds of infections can be a good index for hygienic and sanitation status of the society. This study aimed to determine the prevalence of intestinal parasitic infections among humans referred to Dr. Sharifi Clinical Laboratory, Isfahan, Iran, 2014. In this cross sectional study, 652 fecal samples (286 males and 366 females) from humans who had stool examination test from January to August 2014 were chosen. Microscopic examination for parasitic infections has been carried out using wet mount method. Indistinguishable samples underwent trichrome staining method for accurate identification of protozoa. Intestinal parasitic infections were observed in 68 (10.42 %) out of 652 studied humans. Forty eight Blastocystis hominis (7.36 %), thirteen Endolimax nana (1.99 %), nine Giardia lamblia (1.38 %), five Entamoeba coli (0.76 %), four Chilomastix mesnili (0.61 %) and two Iodamoeba butschlii (0.15 %) were the observed protozoa in the studied population. B. hominis, E. nana and C. mesnili were found to be significantly more prevalent in people with loose stool specimen. Considering the helminthic infections, only one case (0.15 %) that was excreted Taenia saginata proglottids has been documented among 652 studied humans. Based on the findings of the present study intestinal parasitic infections in Isfahan city has been dramatically decreased over the past years and shows a good hygienic and sanitation status of the city.
