Abstract
Three viruses (poliovirus type 1, rotavirus SA-11, and bacteriophage f2) adsorbed on electropositive microporous filters survived at least 5 weeks at 4 degrees C. Poliovirus type 1 and bacteriophage f2 also survived at least 6 weeks at -20 degrees C. Rotavirus SA-11 was not recovered after 1 week at -20 degrees C. The stability of viruses adsorbed on electropositive filters may enable extensive monitoring of viruses in water.
