[Organ reaction and antibody response in experimental bovine cysticercosis]

Antibody response in the course of experimental invasion of calves with the eggs of tapeworm (Taenia saginata) was studied with the use of indirect haemagglutination reaction and microprecipitation in relation to tissue reaction. Indirect haemagglutination was positive for the first time the 21st day, microprecipitation between the 16th and 21st day, at the time of acute pathological changes induced by the developing larvae. In the period of the morphological rest of cysts, beginning about the 50th day p.i., the level of titres stabilized in the haemagglutination reaction which remained positive throughout the time of serological study (250 days p.i.). Precipitation was detectable in our set the 70th and 85th day after invasion at the latest.
