弓型体(Toxoplasma)是弓型体病的病原体。早在1908年 Nicolle 及其同事 Mance-aux 首先从动物发现弓型体。我国1955年于恩庶氏等从猫和兔分离到弓型体,1959年以来,福建、上海、江苏等地相继发现猪群弓型体病的流行。弓型体病是人畜共患的寄生虫病。人类弓型体病,是1914年 Castellani 氏最初从人的脾脏分离到虫体,1939年 Wolf 和 Cowen 氏等从初生儿的脑水肿患者分离出虫体。1964年谢天华氏在江西报告了我国首次发现的人类弓型体病一例。现在,证实世界各大洲都 Toxoplasma is the cause of bow-shaped disease. As early as 1908 Nicolle and his colleague Mance-aux first discovered the bow form from animals. Since 1959, the arch body has been isolated from cats and rabbits in 1955 in our country, such as Fujian, Shanghai and Jiangsu. Bow-shaped body disease is a zoonotic parasitic disease. Human bowopathies were originally isolated from human spleens by Castellani’s in 1914 and isolated from worms of neonatal brain edema in 1939 by Wolf and Cowen et al. In 1964, Xie Tianhua reported a case of human bowel disease found in China for the first time in Jiangxi Province. Now, confirm all the continents of the world
