Bacteroides forsythus sp. nov., a Slow-Growing, Fusiform Bacteroides sp. from the Human Oral Cavity

Abstract
The characteristics of a group of slow-growing, fusiform, fastidious anaerobes isolated from advanced periodontal lesions in human oral cavities were examined. Our results indicated that 12 fusiform Bacteroides strains belong to a new species in the genus Bacteroides. The name Bacteroides forsythus is proposed for these isolates. The type strain is strain ATCC 43037.
