Abstract

Quantitative bacterial counts, concentrations of bile acids and bacterial enzyme profiles were measured in faecal samples from three tribal groups with distinctive dietary patterns in a rural area of northern Nigeria. Samples were obtained from Maguzawa (with a predominantly cereal diet), Hausa (cereal with regular meat consumption) and Fulani (cereal with frequent consumption of cows' milk). Numbers of bacteroides, clostridia and concentrations of bile acids were lower in the Maguzawa than the other dietary groups but these differences were not statistically significant. Bacterial enzyme profiles in each group were similar. The results are discussed with respect to possible influences of diet on the human intestinal microflora.

摘要

在尼日利亚北部农村地区,对三个有着不同饮食模式的部落群体的粪便样本进行了细菌定量计数、胆汁酸浓度测定以及细菌酶谱分析。样本取自马古扎瓦人(主要以谷物为食)、豪萨人(谷物饮食且经常食用肉类)和富拉尼人(谷物饮食且经常饮用牛奶)。马古扎瓦人的拟杆菌、梭菌数量以及胆汁酸浓度低于其他饮食群体,但这些差异无统计学意义。每组的细菌酶谱相似。就饮食对人类肠道微生物群可能产生的影响对结果进行了讨论。
