Serologic differentiation of adult Toxocara and Ascaris.
The antigenic analysis of Toxocara canis a causative agent of visceral larva migrans and Ascaris suum has been carried out. Agar gel double diffusion techniques and its modifications were employed to determine whether or not crude antigens, obtained from the adult parasites: (a) contained components unique for each, (b) could be used to differentiate the parasites serologically. Adult Toxocara canis and Ascanis suum antigens used in this study were found to contain several unique antigenic components. It was shown that antisera produced in rabbits artificially immunized against adult Ascaris and Toxocara could be specifically differentiated from each other by using intragel absorption test.
