Fusobacterium nucleatum subsp. polymorphum ATCC 10953

Fusobacterium nucleatum subsp. polymorphum ATCC 10953 is a Gram-negative, rod-shaped bacterium that typically exists as pairs. This nonsporulating microbe is classified as a chemoheterotroph, primarily deriving its energy from organic compounds in its environment. It thrives in anaerobic conditions, making it well-suited for its natural habitat within the host gut, where oxygen levels are minimal. The optimal growth temperature for this subspecies is approximately 37.0°C, aligning with the physiological temperature of the human body, which further emphasizes its adaptation to host-associated environments. As a member of the Fusobacterium genus, F. nucleatum subsp. polymorphum is notable for its role in the complex microbiota of the gastrointestinal tract. Given its anaerobic nature and specific habitat, F. nucleatum subsp. polymorphum may contribute to various metabolic processes within the gut ecosystem, potentially influencing nutrient absorption and gut health. Its presence in the gut microbiome underscores the intricate relationships between host and microbial communities, suggesting that it may play a role in maintaining microbial balance or contributing to metabolic functions essential for host well-being. Further research into its interactions within the gut environment could provide deeper insights into the symbiotic relationships that define gut microbiota dynamics.
