Bovine serum Cohn fractions were substituted for whole bovine serum in TYI-S-33 medium. Only fraction IV-1 supported attachment, cysteine uptake, and growth of Giardia lamblia. Among the mammalian sources tested, only goat and horse fractions showed activities comparable to that of the bovine fraction. Agglutinating immunoglobulins were identified as deleterious agents in human, rat, rabbit, and dog fractions.
在TYI-S-33培养基中，用牛血清科恩组分替代全牛血清。只有组分IV-1支持蓝氏贾第鞭毛虫的附着、半胱氨酸摄取和生长。在所测试的哺乳动物来源中，只有山羊和马的组分表现出与牛组分相当的活性。在人、大鼠、兔和狗的组分中，凝集免疫球蛋白被鉴定为有害因子。
