| OBJECTIVE: There are many microorganisms transmitted by drinking water and causing epidemic diseases in humans. One of these, Cryptosporidium spp is a protozoon causing enteritis transmitted with contaminated waters. Oocysts of the parasite thrown with human and animal feces cause contamination of drinking water sources in environments with poor sanitation. Oocysts are resistant to the environmental conditions and disinfectants concentrations which are effective on bacteria. Oocysts rise to important problems in water treatment due to remaining alive for a long time in water and the resistance to disinfectants. This study aimed to determine the prevalence of this parasite in the drinking water of the Van region.METHODS: Drinking water samples were taken from 440 sources totally. Water samples were brought to laboratory in five liter clean plastic bins and filtrated from filtration device with vacuum pump which has 0.45 μm cellulose acetate membranes. Particles on the filter were centrifuged by washing in 20 ml of the same water sample, and the sediment was left on the slide. Prepared slides were examined by staining with modified acid fast method after filtering through filtration devices. Three stained slides were prepared for each sample.RESULTS: Cryptosporidium oocysts were detected in 1.13% of the total 440 water samples. Oocysts were determined in 1.57% of 191 surface water sources and 0.82% of 241 drinking water of city and town networks. Cryptosporidium oocysts were positive in 1.55% of 193 water samples from drinking water in rural areas and in |
