[Structural aspects at the individual level in the epidemiological process in human toxoplasmosis].

Intradermoreaction with toxoplasmin in apparently healthy subjects gave positive reactions in 13% of the cases. The mothers of children with neuropsychical diseases and congenital malformations were positive to toxoplasmin in 62-63% of the cases and with the Sabin-Feldman reaction in 9.6-13.8%. High proportions of positive results. (29.1-30%) were obtained with both tests in the children with neuropsychical diseases and congenital malformations. Host-parasite relationships in the early period of embryonic development deeply affects the normal evolution of the embryo and foetus. The individual structural level of the epidemiologic human toxoplasmosis process is conditioned by the moment at which the host-parasite relationships are established.
