[The agglutination test of coracidia of pseudophyllidean cestodes and its use in cestodological research]

Ability of coracidia to agglutination in homologous antiserum was established. The method of reaction of a direct agglutination of coracidia (RDAC) in the culture of alive larvae was described. When comparing the RDAC results in homologous and heterologous variants a dependence of the agglutination pattern on the degree of antiserum homology was established. On the example of RDAC of the cestodes Diphyllobothrium dendriticum and D. ditremum in polyvalent and species-specific antisera to D. dendriticum possibility was shown of RDAC usage in the studies on specific taxonomy of pseudophyllid cestodes.
