[Human larva migrans visceralis infections with toxocara in the German Federal Republic. Serological investigations (author's transl)].

The microprecipitation test on second generation larvae of Toxocara canis has proved to be highly specific for the diagnosis of human larva migrans visceralis infection caused by Toxocara species. Out of a total of 2864 samples examined from 1969 to 1976, 248 were found to be positive. Besides a very frequently occurring eosinophilia eye affections, lung changes and involvement of the CNS are prominent clinical symptoms. The investigations show that larva migrans visceralis infections also occur in West Germany, even if more rarely than in other countries. The diagnosis is only seldom made because of the lack of uniformity of the clinical symptomatology.
