[The Bacteriodaceae flora in the faeces of pigs (author's transl)[].

A total of 180 Bacteroidaceae strains from the fecal specimens of 31 clinically healthy pigs aged 120 to 180 days from 4 farms were isolated in numbers of 10(8)-10(10) per gram feces and differentiated for their morphological, cultural and biochemical properties. 161 of these strains belonged to Bacteroides ruminicola and related species, 10 to B. fragilis ss. fragilis, 3 to B. fragilis ss. vulgatus, 4 to Fusobacterium necrogenes, 1 to F. mortiferum and 1 to a non-motile variant of F. novum. The taxonomic relationships between B. ruminicola and B. oralis are discussed.
