Tannerella forsythia

Tannerella forsythia is an anaerobic, Gram-negative bacterial species of the Cytophaga-Bacteroidetes family. It has been implicated in periodontal diseases and is a member of the red complex of periodontal pathogens.[1][2] T. forsythia was previously named Bacteroides forsythus and Tannerella forsythensis.[3][4][5][6]

Scientific classification

Binomial name
Tannerella forsythia

Tannerella forsythia was discovered by and named after Dr. Anne Tanner who works at The Forsyth Institute located in Cambridge, Massachusetts.

T. forsythia has been identified in atherosclerotic lesions. Lee et al. found that infecting mice with T. forsythia induced foam cell formation and accelerated the formation of atherosclerotic lesions.[7] It has also been isolated from women with bacterial vaginosis.[8] The presence of oral T. forsythia has been found to be associated with an increased risk of esophageal cancer.[9]
