Histopathological studies of acute, chronic and congenital infections of toxoplasmosis in mice.

The histopathological picture of Toxoplasma gondü RH strain (virulent) and Beverley strain (a virulent) was experimentally studied in mice. Nearly all the internal organs and tissues showed pathological changes ranging between the mild congestion to the severe degeneration. However, the changes were more serious in mice infected with RH strain than those infected with Beverley strain.

Comparative study of the Sabin-Feldman dye test and the indirect haemagglutination test in serodiagnosis of toxoplasmosis.

200 women with history of abortion and 100 women with history of uneventful pregnancies were investigated serologically for anti-Toxoplasma antibodies using both the indirect haemagglutination test and the Sabin-Feldman dye test. Our results indicated a role for the first test in seroepidemiological surveys and for routine work. The second test may be reserved for cases with negative haemagglutination test in the presence of strong suspicion of toxoplasmosis.
