Abstract
A total of 180 Bacteroidaceae strains from the fecal specimens of 31 clinically healthy pigs aged 120-180 days from 4 farms were isolated in numbers of 108-1010/g feces and differentiated for their morphological, cultural and biochemical properties. Of these strains, 161 belonged to Bacteroides ruminicola and related species, 10 to B. fragilis ssp. fragilis, 3 to B. fragilis ssp. 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.
