Enzyme-linked immunosorbent assay for the detection of antibodies to Leptospira interrogans serovars hardjo and pomona in cattle. 1983

A B Thiermann, and L A Garrett

An enzyme-linked immunosorbent assay (ELISA), which used the phenol phase of a hot phenol-water extraction as antigen, and the microscopic agglutination test were compared for the detection of antibodies to Leptospira interrogans serovars hardjo and pomona in cattle. Among serum samples from vaccinated cattle, the ELISA (using antiglobulin) was positive to 64% with hardjo antigen and to 78% with pomona antigen, whereas the microscopic agglutination test was positive to only 18% with hardjo and 23% with pomona. There were no ELISA reactions observed among known negative-control samples. The ELISA, using antiglobulin conjugate, was overall a more sensitive technique for the detection of leptospiral antibodies in cattle.

D003429	Cross Reactions	Serological reactions in which an antiserum against one antigen reacts with a non-identical but closely related antigen.	Cross Reaction,Reaction, Cross,Reactions, Cross
D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
