Detection and enumeration of Cryptosporidium oocysts in environmental water samples by Real-time PCR assay
Introduction: The protozoan parasite, Cryptosporidium Spp., widely spreads in both raw and drinking waters. It is the causative agents of waterborne diarrhea and gastroenteritis in the world. In the present study, a molecular assay was used for the detection and quantification of Cryptosporidium oocysts in environmental water samples. Materials and methods: Thirty surface water samples wer...
متن کاملEvaluation of an alternative IMS dissociation procedure for use with Method 1622: detection of Cryptosporidium in water.
U.S. EPA Methods 1622 and 1623 are used to detect and quantify Cryptosporidium oocysts in water. The protocol consists of filtration, immunomagnetic separation (IMS), staining with a fluorescent antibody, and microscopic analysis. Microscopic analysis includes detection by fluorescent antibody and confirmation by the demonstration of 1-4 sporozoites or nuclei after staining with 4',6-diamidino-...

متن کاملOccurrence of Giardia and Cryptosporidium spp. in surface water supplies.
Giardia and Cryptosporidium levels were determined by using a combined immunofluorescence test for source waters of 66 surface water treatment plants in 14 states and 1 Canadian province. The results showed that cysts and oocysts were widely dispersed in the aquatic environment. Giardia spp. were detected in 81% of the raw water samples. Cryptosporidium spp. were found in 87% of the raw water l...
متن کاملGiardia and Cryptosporidium spp. in filtered drinking water supplies.
Giardia and Cryptosporidium levels were determined by using a combined immunofluorescence test for filtered drinking water samples collected from 66 surface water treatment plants in 14 states and 1 Canadian province. Giardia cysts were detected in 17% of the 83 filtered water effluents. Cryptosporidium oocysts, were observed in 27% of the drinking water samples. Overall, cysts or oocysts were ...
