Enteric viruses in renovated water in Manitoba

Abstract

Using various concentration procedures (including the gauze pad method, ultrafiltration, and adsorption-elution), enteric viruses, mainly vaccine strains of polioviruses, were isolated from 61.8% of sewage, 20.5% of effluents, 3.0% of river water, and 6.7% of drinking water samples collected from a waterway system in Manitoba. The presence of polioviruses in the drinking water of the town utilizing this waterway was not correlated with an increase in the number of infectious diseases reported.
