[Concentration of the poliomyelitis virus from water on FP-brand material].
A method of filtration through FP cloth (Petryanov's cloth) has been suggested for concentration of small virus quantities from large volumes of water. The effectiveness of virus removal from water of different degrees of contamination at virus concentrations of 0.05--0.1--0.5--2.5--12.5 PFU/ml was studied. About 88--100% of the initial virus content was removed from sewage, 80--90% from river water, 10--90% from tap water. When the effect of the eluting solutions for the removal of the virus retained on the filter was compared, 1 M NaCl solution in glycocol buffer, pH 11.5, was found to be the most effective. The procedure is characterized by a high rate of filtration, low labour consumption, and simple equipment for filtration.
