ABSTRACT
A method was developed for concentrating infectious pancreatic necrosis virus from hatchery water using positively charged 1-MDS filters. The method consists of passing large volumes (Ca. 1001) of hatchery water through 1-MDS microporous filter followed by the elution of the adsorbed virus using a high pH buffer. The virus adsorbed efficiently to 1-MDS filters when the pH of the water was 5.5 and was eluted optimally with 3% beef extract solution (pH 10). This procedure permitted the processing of 100 1 of hatchery water which resulted in a 300-fold reduction in the volume of water and greater than 90% recovery of the seeded virus.
