Porównanie antygenów produkcji praskiej i lubelskiej w próbie śródskórnej z toksoplazminą

The authors compared the reaction in 114 women caused by toxoplasmine produced by the Parasitological Department of the "Universita Karlova'' in Prague and that one produced by the Parasitological Department of the Institute of Labour Medicine and Rural Hygiene in Lublin. At an equal dilution of antigens (1 : 1000) the first toxoplasmine induces more frequent and violent skin reactions. Some differences, which could not be nearer explained, were also observed when applying various dilutions. An exact standardization of the antigens aind diagnostic methods for toxoplasmosis should be introduced in order to be able to compare different results.
