摘要: 以细胞培养的方法传代弓形虫,建立微孔板弓形虫染色试验。血清与弓形虫虫体经孵育后,用碱性美蓝染色,计数100个虫体,记录染色与未染色虫体的比例,标本中50%虫体着色的稀释度为终点稀释度。弓形虫悬液浓度为109/ml,辅助因子中含1%枸橼酸钠时,弓形虫染色效果最好,微孔板染色试验的稳定性良好。

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.
