[Kinetics of the serological response in the experimental primary hydatid disease of mice infected with Echinococcus granulosus embryophores (author's transl)].

A serological response kinetics study was carried out in CF-1 mice orally infected with Echinococcus granulosus embryophores using immuno-electrophoresis, double diffusion, latex agglutination and passive hemagglutination. Starting from the 76th day after the infection, serum antibodies reach the minimum detectable level by immunoelectrophoresis test. Band number 5, now considered as specific for E. granulosus, was proved to be the first precipitating system exhibited in this test. Double diffusion, latex agglutination and passive hemagglutination tests developed positive results later (125--144 days after infection). Correlation between serologic and anatomo-pathologic findings suggest that hydatid cyst fluid presence in the cysts is necessary for circulating antibodies production.
