The immune response of the definitive hosts to diphyllobothriid antigens.

It was established that antigens of diphyllobothriids entered the organisms of nestlings of gulls (Larus fuscus) and terns (Sterna hirundo) through the intestine. In terns, the most intensive neutralization of parasite antigens was found in the intestine inducing a weak response of the immune system. In gulls, there was no complete neutralization of the parasite antigens in the intestines. The antigens penetrated into the blood stimulating a response of the immune system. The intensity of the local immunity of terns seems to result from the absence of invasion in adult birds.

On the methods of obtaining diphyllobothriid surface antigens.

A new method of obtaining the diphyllobothriid surface antigens has been developed. It allows to obtain antigens with the increased content of the surface components of worm strobila. It was found that the antigens from extracts I are relatively more active than the antigens from extracts II and III.

Coracidia agglutination reaction of pseudophyllid cestodes and its application in cestode studies.

The ability of cestode coracidia to agglutinate in homologous antiserum was established. The method of direct agglutination of coracidia (RDAC) in a culture of living larvae is described. The comparison of RDAC results in homologous and heterologous variants shows a dependence of the agglutination pattern on the degree of antiserum homology. By the example of RDAC of the cestodes Diphyllobothrium dentriticum and D. ditremum in polyvalent antisera and in antisera species-specific to D. dendriticum a possibility is shown of using RDAC in studies on species taxonomy of pseudophyllid cestodes.
