Detection of rotavirus in sewage and creek water: efficiency of the concentration method.

ABSTRACT

Simian rotavirus SA-11 experimentally seeded, was recovered from raw domestic sewage by a two-step concentration procedure, using filtration through a positively charged microporous filter (Zeta Plus 60 S) followed by ultracentrifugation, effecting an 8,000-fold concentration. By this method, a mean recovery of 81% +/- 7.5 of the SA-11 virus, was achieved.
