The faecal microflora of breast-fed infants, weaned children and adults has been examined in rural Nigeria and urban U.K. Breast-fed infants had a similar anaerobic flora dominated by bifidobacteria but bacteroides were isolated in less than a quarter of either community. Weaned children in both communities had greater numbers of bacteroides and clostridia than breast-fed infants. Even higher numbers of bacteroides and clostridia were present in U.K. adults but not in Nigerian adults. Numbers of bacteroides and clostridia were greater in a group of Nigerian infants drinking cow's milk than those receiving breast milk alone and lower in a group of weaned children with diarrhoea compared with uninfected subjects.
在尼日利亚农村和英国城市对母乳喂养的婴儿、断奶儿童及成年人的粪便微生物群进行了检测。母乳喂养的婴儿具有相似的以双歧杆菌为主导的厌氧菌群，但在这两个群体中，类杆菌的分离率均不到四分之一。两个地区断奶儿童的类杆菌和梭状芽孢杆菌数量均多于母乳喂养的婴儿。英国成年人中类杆菌和梭状芽孢杆菌的数量更高，但尼日利亚成年人中并非如此。一组饮用牛奶的尼日利亚婴儿的类杆菌和梭状芽孢杆菌数量多于仅接受母乳喂养的婴儿，而一组患有腹泻的断奶儿童的类杆菌和梭状芽孢杆菌数量低于未感染的受试者。
