作者在非洲一个以牛奶为主食的游牧部落进行观察,该部落饮食几乎全为牛奶,而这族人极不易受阿米巴的感染。这种现象表明牛奶饮食和溶组织内阿米巴之间可能存在着生态协调的一致性的。然而牛奶的这种作用必须在低铁的情况下才能发挥,并能为铁的补充所逆转。作者随机抽取81例该部落成人为研究 The authors looked at a nomadic tribe predominantly based in Africa where the diet of the tribe is almost exclusively milk and the tribe is extremely vulnerable to amoebic infection. This phenomenon suggests that there may be ecological coordination between the milk diet and Entamoeba histolytica. However, this effect of milk must be exercised in the case of low iron and reversed for iron supplementation. The authors randomly selected 81 tribal adults for the study
