Abstract
Twenty-four treated municipal wastewater samples were collected during one-year study period and examined for the presence of helminthes eggs, Cryptosporidium oocysts, and Giardia cysts to compare between their occurrences. Modified Bailenger method was used in this study to detect and enumerate nematode eggs in the treated wastewater samples, while polymerase chain reaction (PCR) technique was used to detect Cryptosporidium and Giardia in the same treated wastewater samples. Results revealed that Ascaris eggs were detected in only 8.33% out of 24 treated wastewater samples, while Cryptosporidium oocysts and Giardia cysts were detected in 20.83 and 12.5% out of the same 24 treated wastewater samples, respectively. The public's health is at risk since treated wastewater used for agriculture still contains Giardia cysts and Cryptosporidium oocysts, even if it satisfies the nematode criteria.
