Abstract
Two microimmunodiffusion tests (MIDT) for detection and measurement of ovine progressive pneumonia antibody are described. Substrates of various salt concentrations and pH were used to determine the optimal conditions for the tests. In comparisons between 2 MIDT and 1 macroimmunodiffusion test, sera from cull ewes were used. The MIDT require less reagents and were more responsive than the macroimmunodiffusion test. After extended incubation of the test materials, results in all 3 tests were comparable.
