Fusobacterium nucleatum subsp. nucleatum ATCC 23726

Fusobacterium nucleatum subsp. nucleatum ATCC 23726 is a Gram-negative, nonsporulating rod-shaped bacterium that thrives in anaerobic environments, with an optimal growth temperature of 37.0°C. This subspecies is associated with host organisms, indicating a potential symbiotic or pathogenic relationship within specific biological contexts. As an anaerobe, F. nucleatum subsp. nucleatum relies on the absence of oxygen for its metabolic processes, which is characteristic of many bacteria that inhabit the human oral cavity and gastrointestinal tract. The unique morphological and physiological traits of F. nucleatum subsp. nucleatum contribute to its ecological niche, where it may play a role in the complex microbial communities found in host-associated environments. Its ability to flourish at the human body temperature suggests an adaptation to the warm, nutrient-rich surroundings of the host, potentially impacting host health and microbiome dynamics. Understanding the characteristics of this subspecies is crucial for further studies on its role within human-associated microbiomes, particularly in relation to oral health and systemic conditions.
