| Abstract | ||||
| In this study, the prevalence of astrovirus (AstV), norovirus (NoV), and group C rotaviruses (RVC) were described in urban sewage, sewage sludge, river water, and sediment samples from Egypt. AstV, NoV, and RVC were detected in 58.3%, 33.3%, and 25% of the raw sewage samples; in 33.3%, 25%, and 16.6% of the treated sewage samples; and in 66.6%, 16.6%, and 8.3% of the sludge samples, respectively. On the other hand, AstV, NoV, and RVC were detected in 25%, 16.6%, and 8.3% of the river water samples and in 16.6%, 8.3%, and 0% of the river sediment samples, respectively. The study revealed that AstV genogroup B and NoV genogroup I are the most frequent genotypes in the Egyptian environment. Furthermore, the peak prevalence of AstV and RVC in river water and raw sewage samples was found in winter months however there was no clear seasonality for NoV spread. This study support the importance of considering viral markers to ensure the quality of water and the utilization of these markers as additional tests for the characterization of water contamination. | ||||
