| detection of poliovirus, hepatitis a virus and rotavirus from sewage and water samples. | a modified adsorption-elution technique for concentration of enteric viruses from sewage and water samples was developed. the viruses in water were concentrated by negatively charged membrane filtration, eluted with 2.9% tryptose phosphate broth containing 6% glycine ph 9.0, and reconcentrated using centrifugation by a speedvac concentrator. the presence of poliovirus, hepatitis a virus (hav) rna, and rotavirus antigen was determined by cell culture isolation, nested polymerase chain reaction (n ... | 2000 | 11023063 |
