Detection of antibody in Aleutian disease of mink: comparison of enzyme-linked immunosorbent assay and counterimmunoelectrophoresis.
Experiments were undertaken to investigate the potential of the enzyme-linked immunosorbent assay (ELISA) as a screening test for the diagnosis of the 2 known naturally occurring forms of Aleutian disease of mink. Anti-Aleutian disease virus (ADV) antibody activity was not detectable in the sera of mink with nonprogressive Aleutian disease despite the demonstration of antibody by counterimmunoelectrophoresis (CIEP)  in the same sera. Anti-ADV antibody was detectable in 93% of sera from mink at various stages of experimentally induced progressive Aleutian disease. False-negative reactions occurred in sera which demonstrated high anti-ADV antibody titers by CIEP. As a consequence of the high prevalence of false-negative reactions, the ELISA was not considered to be an effective screening test. However, using CIEP as an indicator of ADV infection, the ELISA may be useful in differentiating mink with nonprogressive Aleutian disease from mink with progressive Aleutian disease.
