The first step of the plant pterin branch is catalyzed by GTP cyclohydrolase Ⅰ and the first step in the conversion of chorismate to pABA is mediated in plants by aminodeoxychorismate synthase.

叶酸分子是由喋呤和对氨基苯甲酸从头合成的，二者合成的关键酶腺苷三磷酸环化水解酶和氨基脱氧分支酸合成酶已得到克隆鉴定。

The additional supplements including glucose,ascorbic acid and insulin had the enhancement effects on C.andersoni development,while folic acid had no significantly effect on C. andersoni development and calcium pantothenate had inhibited effect.When added 50 mmol/L glucose,50μg/ml ascorbic acid,0.3 U/ml insulin into 10%FCS RPMI-1640 medium,the proliferation of C.andersoni had a great significantly increase,and the gene copies of C.andersoni were 8-fold compared with that in 10%FCS RPMI-1640 medium.

冻融法+蛋白酶K法+声裂法提纯隐孢子虫卵囊DNA效果最佳，其次为冻融法+声裂法和蛋白酶K法+声裂法，冻融法+蛋白酶K法效果最差。10%FCS是培养安氏隐孢子虫的最佳FCS浓度，葡萄糖、维生素C和胰岛素都具有促安氏隐孢子虫增殖作用，泛酸钙无促虫体增殖效果，而叶酸则抑制虫体增殖。10%FCS RPMI-1640培养液中加入50 mmol/L葡萄糖，50μg/ml维生素C和0.3 U/ml胰岛素促安氏隐孢子虫增殖效果最显著，虫体增殖8倍。
