SUMMARY Non-sporing strictly anaerobic bacteria were isolated from human faecal samples from England, Scotland, USA, India, Uganda and Japan. Strains were assigned to genera on the basis of the Gram reaction and on the type of fatty acid produced from glucose. Analysis of these acids was by gas-liquid chromatography. The isolates were further classified on the basis of various biochemical reactions. Bacteroides fragilis was the non-sporing anaerobe most frequently isolated from human faeces. Bifidobacterium adolescentis and Eubacterium aerofaciens were also frequently isolated. Stool samples from India, Uganda and Japan contained a larger proportion of eubacteria and fewer Bacteroides spp. than did the samples from England, Scotland and the USA.
