Leptotrichia buccalis

Leptotrichia buccalis is a species of bacteria that is part of the normal microflora of the human mouth and throat. It is a Gram-negative, rod-shaped bacterium that is often associated with various oral diseases and infections.

Taxonomy

Leptotrichia buccalis belongs to the phylum Fusobacteria, class Fusobacteriia, order Fusobacteriales, family Leptotrichiaceae, and genus Leptotrichia. The species was first described in 1921 by James Howard Brown.

Characteristics

Leptotrichia buccalis is a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen. It is non-motile and does not form spores. The bacterium is catalase-negative and oxidase-negative.

Pathogenicity

While Leptotrichia buccalis is part of the normal oral microflora, it can become pathogenic under certain conditions. It has been associated with various oral diseases, including periodontitis, gingivitis, and endodontic infections. It can also cause systemic infections in immunocompromised individuals.

Treatment

Treatment of infections caused by Leptotrichia buccalis typically involves antibiotics. The bacterium is generally susceptible to penicillin, metronidazole, and clindamycin.
