A Motile Strain of Fusobacterium Polymorphum

Genome Sequence of Fusobacterium nucleatum Subspecies Polymorphum — a Genetically Tractable Fusobacterium

Fusobacterium nucleatum is a prominent member of the oral microbiota and is a common cause of human infection. F. nucleatum includes five subspecies: polymorphum, nucleatum, vincentii, fusiforme, and animalis. F. nucleatum subsp. polymorphum ATCC 10953 has been well characterized phenotypically and, in contrast to previously sequenced strains, is amenable to gene transfer. We sequenced and anno...

Genetic and biochemical characterization of FUS-1 (OXA-85), a narrow-spectrum class D beta-lactamase from Fusobacterium nucleatum subsp. polymorphum.

Previous studies have reported beta-lactamase-mediated penicillin resistance in Fusobacterium nucleatum, but no beta-lactamase gene has yet been identified in this species. An F. nucleatum subsp. polymorphum strain resistant to penicillin and amoxicillin was isolated from a human periodontitis sample. DNA cloning and sequencing revealed a 765-bp open reading frame encoding a new class D beta-la...

Oral Fusobacteria.

The genus Fusobacterium was proposed by Knorr (1922) for the pointed, nonsporulating, gram-negative, anaerobic bacilli found in the oral cavity. On the basis of morphology, three species were named, Fusobacterium nucleatum, Fusobacterium polymorphum, and Fusobacterium plauti-vincentii. Similarly, Hine and Berry (1937) described three species, based primarily on morphological and cultural charac...
