Littman Oxgall Agar was modified by adding an extract of Guizotia abyssinica seeds with a water diluent for rehydration. In this medium, colonies of Cryptococcus neoformans became brown, but the color failed to develop in eight other yeasts and yeast phases of diphasic organisms. The depression of saprophytic fungi noted on Littman Oxgall Agar was not lost in the modification.
通过添加用水稀释剂复水的埃塞俄比亚芥种子提取物对利特曼牛胆汁琼脂进行了改良。在这种培养基中,新型隐球菌的菌落变成褐色,但在其他八种酵母和双相生物体的酵母阶段中颜色并未显现。在改良后的培养基中,利特曼牛胆汁琼脂上观察到的腐生真菌抑制现象并未消失。
