This study examined the faecal flora on days 4, 14, and 28 of 17 breast fed babies and 26 bottle fed babies receiving a modern infant formula based on demineralized whey. Generally among breast fed babies bifidobacteria and staphylococci were the predominant organisms, whereas in the formula fed babies the predominant organisms were enterococci, coliforms, and clostridia. Despite the extensive modification of cows' milk to make an infant formula resemble human breast milk, the results are very similar to those previously reported with unmodified cows' milk baby feeds. The exact dietary factor responsible for these microbiological differences is unclear and in succeeding papers we have looked at the effects of protein quality, in particular the content of whey proteins, casein, and lactoferrin.
本研究检测了17名母乳喂养婴儿和26名接受以脱矿质乳清为基础的现代婴儿配方奶粉喂养的人工喂养婴儿在第4天、第14天和第28天的粪便菌群。一般来说，母乳喂养婴儿中双歧杆菌和葡萄球菌是主要菌群，而人工喂养婴儿中主要菌群是肠球菌、大肠菌群和梭菌。尽管对牛奶进行了广泛改性以使婴儿配方奶粉类似母乳，但结果与先前报道的未改性牛奶婴儿喂养的结果非常相似。造成这些微生物差异的确切饮食因素尚不清楚，在后续论文中我们研究了蛋白质质量的影响，特别是乳清蛋白、酪蛋白和乳铁蛋白的含量。
