Inactivation of aggregated poliovirus by bromine is characterized by a continuously decreasing reaction rate. Poliovirus released from infected cells in these experiments by alternate freezing and thawing in water without electrolytes has always been aggregated. The aggregates persist even on 7,000-fold dilution in ion-free water. Virus similarly released into phosphate-buffered saline solution may be well dispersed, but it aggregates when sedimented into a salt-free sucrose gradient or when it is diluted as little as 10-fold in water. Large one-step dilutions of dispersed virus in water remain dispersed. Aggregated virus was not dispersed by one-step dilution (7,000-fold) in distilled or untreated lake water but was dispersed if phosphate-buffered saline or clarified secondary sewage plant effluent was used as diluent. Dispersed virus aggregates at all dilutions in alum-treated, finished water from the city filter plant. This may be the result of complex formation with insoluble material rather than virion-virion aggregation. A simple procedure is described for rendering a very dilute suspension of mixed virion aggregates into a three-part spectrum of sizes.
