Abstract: A modified dye test with microplate was to be established to detect Toxoplasma antibodies with cell-cultured Toxoplasma gondii. Numbers of stained and unstained tachyzoites were estimated in every 100 tachyzoites in each well after dyeing with methylene blue. The dilution with 50% tachyzoites stained was used as final dilution. Better results of the microplate dye test has been received when the concentration of tachyzoites in suspension reaches 109/ml with 1% sodium citrate as accessory factor.

Key words: Toxoplasma gondii, Dye test, Microplate
