title: Enzyme-linked immunosorbent assay for detecting antibodies in swine infected with Mycobacterium avium.
abstract: Enzyme-linked immunosorbent assay (ELISA) was used for detecting the antibodies in sera from swine experimentally infected with Mycobacterium avium. Positive ELISA reactions were observed in the sera of each of six swine at postinoculation weeks 2, 4, 6, 8, and 10; no reaction was observed in noninoculated controls. The ELISA reactions were observed in each of two swine at 4, 6, 8, 10 weeks following exposure to M avium-infected swine. Mycobacterium avium-purified protein derivative and killed cells of M avium serotype 4/8 and serotype 8 provided suitable ELISA reactions in M avium-infected swine.
