Comparison of 3 Methods of Concentration of Poliovirus in Water Samples and Establishment of an Improved Method
Abstract: This paper described the quantative eomprison of 3 methods concentrating poliovirus type 1 artificially added into the water samples, The preliminary results showed that the recovery rate of the virus in the water samples was similar (47—49%)among the 3 methods, It was discovered that the addition of 1% NaCl into virus contaminted distilled water sample increased significantly the virus-recovery rate with milliporous membrane filtrating method and we established an improved process of virus concentration of...
