title: Detection of antibodies against porcine parvovirus in swine sera by enzyme-linked immunosorbent assay.
abstract: An enzyme-linked immunosorbent assay (ELISA) was developed for detection of antibody against porcine parvovirus in swine sera. The antigen used for the assay was partially-purified virus treated with fluorocarbon and shown to contain 7 proteins by sodium dodecylsulfate-polyacrylamide gel electrophoresis. Of these proteins 83-, 64- and 60-K proteins reacted in Western immunoblotting with swine serum after infection with porcine parvovirus. Antibody responses were demonstrated by ELISA in pigs subcutaneously-infected with porcine parvovirus as by hemagglutination-inhibition (HI) test and Western immunoblotting reaction with the 83-, 64- and 60-K viral proteins. The results of ELISA on random swine-serum samples were well-correlated with those of the HI test. These findings indicate the usefulness of the ELISA as a serological tool for porcine parvovirus infection.
