A new method for rapidly removing contaminating micro-organisms from porcine parvovirus or pseudorabies virus master-seed suspensions.
Virus-contaminated cell cultures are a major problem in the bio-industry. Methods employed to date to remove contaminating micro-organisms are slow and costly, and a new method is proposed here which is simple and rapid. The method uses polyacrylamide beads coated with specific antibodies which yielded bead-antibody-virus complexes when suspended in the virus solution to be cleared. The purified virus was propagated in cells which show phagocytic activity. Vaccine master-seed virus is shown to be rapidly cleaned and propagated using this method.
