Fusobacterium polymorphum ATCC 10953

Fusobacterium polymorphum ATCC 10953 is a Gram-negative, anaerobic, rod-shaped bacterium primarily found in the gut of hosts. As a chemoheterotroph, it derives its energy from organic compounds in its environment. The bacterium typically exists in pairs and does not exhibit mobility, despite the presence of flagella, suggesting that its movement is limited or not utilized in its ecological niche. Fusobacterium polymorphum is classified as mesophilic, with an optimal growth temperature of 37°C, which aligns with the average temperature of the mammalian gut, making it well-adapted to its habitat. This bacterium is nonsporulating and possesses two replicons, indicating a stable genetic structure that may contribute to its persistence in the gut environment. Understanding the ecological role of Fusobacterium polymorphum is crucial, as its presence in the gut microbiota can influence the overall health of the host. By engaging in complex interactions with other microbial species and the host immune system, it may play a significant role in maintaining gut homeostasis or potentially contributing to dysbiosis under certain conditions. The specific accessions NC_009506.1 and NZ_CM000440.1 provide genomic information that can aid in further studies of its biological functions and interactions within the gut ecosystem.
