—The aim of this study was to assess the presence of Cryptosporidium
in the water of school swimming pools located in Dubai, UAE
. The swimming pool water samples from five schools were tested for Cryptosporidium
oocysts and Giardia
cysts using direct immunofluorescence assay. Sa
mples were also examined for the total coliform, fecal coliform and heterotrophic bacteria using the membrane filtration technique. The majority of the tested swimming pool water samples were found contaminated with either Cryptosporidium
oocysts or Giardia
cysts or both. Cryptosporidium
oocysts were found to be in the higher range (1-15 oocysts per liter) than that of Gi ardia
cysts (1-4 cysts per liter). All of the swimming pool water samples were found negati
ve for the presence of traditional bacterial indicators. Howe
, direct DAPI staining detected several types of viable but nonculturable (VBNC) bacteria on the membrane filter. In conclusion, based on the preliminary data obtained, Cryptosporidium
were found to be present in the tested schools’ swimming pool water. Future work on a long term monitoring of both parasites is highly recommended to enhance the swimming pool water quality and ensure the public health safety which will help in maintaining a hygienic and healthy recreational water environment.
