[Comparative studies of the standardization of erysipeloid immune sera "Dessau" from swine using the mouse-protection test and ELISA].

Different serological methods were used in determining the valence of red murrain immune sera. By using a grow test it is possible to accomplish an immunological differentiation of the immune sera. The used ELISA was tested in comparison to the conventional mouse protective test (PRIGGE, 1950) with regard to its valuation of immune sera. Both procedures have been tested on a possible correlation. In almost all cases a correlation between high titres in ELISA and a mouse protective value over 100 I.E. could be proven. The statistical processing of the test results proved an assumed correlation of both procedures. But it is necessary to carry out further research in order to be able to recommend this procedure as an alternative for the mouse protection test.
