[Demonstration of antibodies during experimental toxocarosis using antigenic extract prepared from the adult parasit].

The detection of antibodies in subjects with visceral larva migrans syndrome caused by Toxocara canis is usually carried out with antigenic larvae, whose preparation presents some difficulties. Results obtained using extracts prepared from adult parasites show that such antigens are quite suitable for the detection of antibodies present in visceral larva migrans syndrome. This phenomenon is easily understood when one considers that there are numerous antigenic points in common between the different stages of the evolution of this parasite.
