[Researches on possible applications of mycoserological methods of diagnosis in phytopathology. III. Information: about relations between the number of reacting epitops and the specificity of the reactions (author's transl)].

Several immunsera of rabbit were developed against 8 Fusarium ssp. on the basis of 10 intravenous injections with an increasing dose of the antigen. By means of these it was possible to differentiate several antigen-epitops by using the method of multidimensional double-diffusion. The number and the specificity of these epitops allows to get an insight as well into the reaction-behaviour of the Fusarium-species on test as in there serological relationship. Finally the serological result were discussed in comparison with the classification of the species within the present classification systems of Fusarium.
