| pubmed-article:6322477 | pubmed:abstractText | Five reservoirs were investigated for the presence of enteroviruses by using simultaneously two methods for concentration (PE60 and yeast cells) and two techniques for isolation (inoculation into suckling mice and into cell cultures). The average rate of virus positive samples was lower in reservoir water than in the water of the adjoined rivers. The paper discusses the possibilities of viral self-purification in reservoir water and the advantages of its use for drinking purposes after adequate treatment. | lld:pubmed |
