Treponema denticola ATCC 35405

Treponema denticola ATCC 35405 is a Gram-negative, spiral-shaped bacterium that thrives under anaerobic conditions, functioning as a chemoheterotroph. This microbe is primarily found in the oral cavity, especially within periodontal tissues where it contributes to oral diseases such as periodontitis. It is considered an obligate anaerobe, meaning that it cannot grow in the presence of oxygen, relying instead on the fermentation of organic compounds to meet its nutrition needs. The spiral shape of Treponema denticola is characteristic of the spirochete family, which enables its motility through a unique axial filament structure. This allows the bacterium to navigate the viscous environment of the subgingival biofilm and adheres to tooth surfaces and periodontal pockets. It is typically found in symbiosis with other oral bacteria, forming complex microbial communities that influence host health and disease progression. As a chemoheterotroph, T. denticola derives energy from organic substrates, which include polysaccharides and proteins in the oral environment. This metabolic pathway is vital for its survival, especially in the nutrient-poor conditions of the periodontal pocket. This microbe is also noteworthy for its role in the pathogenicity of periodontal disease. It is linked to the degradation of the periodontal tissue, influencing inflammation and providing a favorable environment for further microbial colonization. Furthermore, T. denticola produces virulence factors such as proteases and endotoxins, contributing to tissue damage and the immune response. Its presence is often associated with the severity of periodontal disease, making it a target for therapeutic strategies aimed at improving oral health.
