Leptotrichia buccalisRANK: SpeciesTAXONOMY: Bacteria -> Fusobacteria -> Fusobacteriia -> Fusobacteriales -> Leptotrichiaceae -> Leptotrichia -> Leptotrichia buccalis OVERVIEW: Leptotrichia buccalis is a common oral bacteria. Previously, all human oral Leptotrichia isolates were lumped into the single species, L. buccalis. From 16S rRNA studies we now recognize that there are approximately 20 Leptotrichia species, five of which been named [2]. The early literature was confused as two organisms were called Leptotrichia buccalis [1].Leptotrichia buccalis requires anaerobic culture for initial isolation. Some strains are reported to grow aerobically in the presence of CO2 on subsequent passage.Commonly found in dental plaque.Leptotrichia buccalis is not commonly pathogenic, but has on rare occasions been associated with bacteraemia and endocarditis, particularly in neutropenic patients [3]. It has been endodontic leasions by checkerboard hybridization [4].Identified as a constituent of the oral microbiome by Human Oral Microbiome Database. This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072]
