Abstract :Objective: Cryptosporidium sp. is a protozoan which is highly resistant to external environmental conditions and chlorination and can lead to severe diarrhea in immunosuppressed persons. Oocysts of this parasite, is excreted by human and animal feces, lead to contamination of potable insert ignore into journalissuearticles values(drinking); water supplies in environments with poor sanitation. Our aim is to investigate the presence of oocysts in some potable water samples taken from different points of Erzurum city center and around on different months. Methods: Totally 120 water samples were collected from 40 random different points of Erzurum city center and around on April, May and July. Of the 120 samples, 45 were from city water system and 75 from fountain and wells water. Water samples collected within 5 liter tanks were filtered by using membrane filter. From each sample preparation were done by using modified acid fast staining method and then examined under microscope. Results: Cryptosporidium sp. oocysts were detected on 18 insert ignore into journalissuearticles values(15.0%); of total 120 water samples. 6 insert ignore into journalissuearticles values(13.3%); of these positive samples were from city water system and the other 12 insert ignore into journalissuearticles values(16.0%); were from fountains and wells. According to the seasonal distribution of positive samples 9 insert ignore into journalissuearticles values(22.5%); have been taken on April, 7 insert ignore into journalissuearticles values(17.5%); on May and 2 insert ignore into journalissuearticles values(5.0%); on July. Conclusion: Results of this study have shown that source of water supplies in our region are notably contaminated with Cryptosporidium sp. oocysts, and the rate of contamination is higher on April and May when compared with July.
