Cultures of E. coli are capable of inhibiting the absorption of vitamin B(12) in the rat. Their inhibitory effect is totally abolished when the organisms are killed by heat and partially abolished when test doses of labelled B(12) are previously bound by intrinsic factor.
大肠杆菌培养物能够抑制大鼠对维生素B12的吸收。当这些微生物被加热杀死时,它们的抑制作用完全消失;而当标记的B12试验剂量预先与内因子结合时,其抑制作用部分消失。
