刚地弓形虫感染对于正常人危害不大,而当免疫耐受患者发生脑内感染和胎儿宫内感染则后果严重,甚至致命。有关弓形虫感染研究的进展较快,但许多病理生理现象仍然解释不清。通过体外感染模型可研究弓形虫和宿主间的许多复杂关系。这类研究需要准确检测细胞内是否有弓形虫感染和/或增殖。常用光学显微镜或氚标记尿嘧啶检测。 Toxoplasma gondii infection is not harmful to normal people, but when the immune tolerance of patients with intrauterine infection and intrauterine infection, the consequences are serious and even fatal. Progress on Toxoplasma infection is fast, but many pathophysiological phenomena are still unclear. Many intricate relationships between Toxoplasma gondii and hosts can be studied by in vitro infection models. Such studies require accurate testing of cells for Toxoplasma infection and / or proliferation. Commonly used optical microscopy or tritiated uracil detection.
