BACKGROUND: Within the past few decades, there has been an increase in the number of water-borne disease outbreaks and emergence of newly recognized waterborne parasites. Several factors which contribute to the spread of these diseases include: water, heavy rains and agricultural residues which transfer the parasites to water surface from the soil. The aim of this study was to detect the presence of parasites in the river and drinking water of Al-Wahdaa and Al-Rasheed Drinking Project and household water tanks from some regions of Baghdad. METHOD: Forty samples were collected from river and drinking water of Drinking Project. Fifty four samples of household water tanks were collected from some regions of Baghdad. RESULTS: Cryptosporidium oocyst, which was founded in river water samples are more than those in drinking water. Furthermore, it was existed in Diyala Bridge &Taha Mosque from April - August and oocyst was diagnosed by using of Zheil-Neelson. Wet mount slide method was applied to detect cysts of free-living amoeba Acanthomoeba, Naegleria. The number of cysts in July and August were higher than other months for Drinking Project and the water tanks for all regions. CONCLUSION: These results emphasize the importance screening of the water to prevent possible of the spread of parasitic protozoan and that the cracks occurrence in drinking water pipes between the stations and houses led to contamination of water with the infective stage of parasites, especially in the areas that are near agricultural fields which polluted with the cows' waste.
