Answer

The diagnosis of toxoplasmosis is confirmed with the demonstration of T gondii organisms in blood, body fluids, or tissue. T gondii may be isolated from the blood via either inoculation of human cell lines or mouse inoculation. Mouse inoculation may require a longer time to yield results and also is likely to be more expensive. Isolation of T gondii from amniotic fluid is diagnostic of congenital infection by mouse inoculation.
