| Description | Fusobacterium russii is a microorganism that thrives in a temperature range of 25-40°C, categorized as mesophilic. It is a chemoheterotroph, meaning it obtains its energy by breaking down organic compounds, such as proteins, carbohydrates, and fats. F. russii produces energy through anaerobic respiration, utilizing the fermentation of glucose as its primary metabolic pathway. The bacterium is classified as gram-negative, characterized by its thin peptidoglycan layer and outer membrane. F. russii has a unique fusiform (spindle-shaped) morphology, with a length of approximately 2-5 μm and a width of 0.5-1 μm. Fusobacterium russii is ubiquitous, found in various body sites across all species, including the mouth, gastrointestinal tract, and skin. It is an obligate anaerobe, meaning it requires a lack of oxygen to survive, and is sensitive to the presence of atmospheric oxygen. In its natural environment, F. russii plays a crucial role in the breakdown of organic matter, contributing to the recycling of nutrients. Its ability to thrive in a wide range of environments, from the oral cavity to the gut, has led to its classification as a commensal microbe, living in symbiosis with its host. F. russii has been linked to various human diseases, including periodontitis, gastroenteritis, and possibly even colon cancer. Further research is needed to fully understand the implications of this microbe on human health and its potential applications in fields such as biotechnology and medicine. As F. russii is a relatively understudied species, ongoing research aims to elucidate its metabolic pathways, cell structure, and interactions with its host. By shedding light on the biology of this microbe, scientists hope to unlock new avenues for therapeutic interventions and improve our understanding of the complex relationships between microbes and their human hosts. |
