对九名农村健康日本人和八名城市健康加拿大人的粪便微生物群进行了检查。这两个人群分别吃典型的日本和西方饮食。日本人的真细菌（P < 0.01）、双歧杆菌（P < 0.05）、杆菌（P < 0.01）、乳酸杆菌和韦荣球菌的数量以及双歧杆菌的出现频率高于加拿大人。在加拿大人中发现了更多数量的拟杆菌和卵磷脂酶阴性梭菌。 从日本人的粪便中分离出 23 属、超过 75 个物种或生物变型，从加拿大人的粪便中分离出 18 属、超过 66 个物种或生物变型。普通拟杆菌数量（P < 0.05）。日本人中球状梭菌 (P < 0.001) 和 C. tertium (P < 0.05) 以及 B.uniformis (P < 0.01)、(P < 0.05) 和 Bacillus spp. (P < 0.01) 的发病率显着低于加拿大人。相反，产气真杆菌 (P < 0.01) 的数量显着低于加拿大人。日本人的青春双歧杆菌生物变种 b (P < 0.01) 和枯草芽孢杆菌 (P < 0.01) 的发病率显着高于加拿大人。这些结果表明，摄入西方饮食可导致粪便中厌氧革兰氏阳性杆菌显着减少，以及粪便中拟杆菌和梭状芽胞杆菌数量增加。
The fecal microflora of nine rural healthy Japanese and eight urban healthy Canadians was examined. The two populations ate typical Japanese and western diets, respectively. The numbers of eubacteria (P < 0.01), bifidobacteria (P < 0.05), bacilli (P < 0.01), lactobacilli and veillonellae and the frequency of occurrence of bifidobacteria were higher in the Japanese than in the Canadians. Higher numbers of bacteroides and lecithinase-negative clostridia were found in the Canadians. Twenty-three genera and over 75 species or biovars were isolated from the feces of Japanese and 18 genera and over 66 species or biovars from the Canadians. The numbers of Bacteroides vulgatus (P < 0.05). Clostridium coccoides (P < 0.001), and C. tertium (P < 0.05) and the incidence of B. uniformis (P < 0.01), (C. innocuum (P < 0.05), and Bacillus spp. (P < 0.01) were significantly lower in the Japanese than in the Canadians. In contrast, the numbers of Eubacterium aerofaciens (P < 0.001), and the incidence of Bifidobacterium adolescentis biovar b (P < 0.01) and Bacillus subtilis (P < 0.01) were significantly higher in the Japanese than in the Canadians. These findings suggest that significant reductions in anaerobic gram-positive bacilli and increased numbers of bacteroides and clostridia in the feces were induced by the intake of a western diet.
