RESUMO
Samples of raw sewage, primary effluent, and secondary effluent from a large activated-sludge purification plant near Melbourne (Victoria, Australia) were collected every second week for 1 year. Viruses were detected in all secondary effluent samples and in six of seven samples obtained after final chlorination. Adenoviruses (85% reduction) and reoviruses (28% reduction) were removed less efficiently by this treatment process than were enteroviruses (93% reduction). In addition, 57 of 171 samples of effluent tested were positive for either adenoviruses or reoviruses, or both, when enteroviruses were not isolated. This clearly shows that the use of enteroviruses as sole indicators of viruses in water may miss up to one-third of instances of viral contamination. Enteroviruses and adenoviruses were isolated most frequently in HeLa-R cell cultures, whereas reoviruses were most often isolated in primary monkey kidney cells.
