| Description | Muribaculum intestinale is a Gram-negative, nonsporulating, anaerobic bacterium that thrives within the intestinal microflora of animals, notable for its role in the gut microbiome of mice. This mesophilic microbe exhibits an optimal growth temperature of around 37 degrees Celsius, which aligns with the body temperature of its natural host. M. intestinale is a chemoheterotroph, relying on fermentative metabolism to derive energy from various organic compounds present in the gut environment. The presence of M. intestinale in the gut is significant as it contributes to the overall health of the host by participating in the fermentation of complex carbohydrates, ultimately aiding in nutrient absorption and synthesis of short-chain fatty acids, which are vital for gut health and immune function. Its ability to thrive in an anaerobic environment allows it to effectively colonize the intestinal tract, where oxygen levels are minimal. Moreover, M. intestinale is positioned within a complex ecosystem where microbial interactions can influence host physiology and disease susceptibility. Research into this bacterium highlights its potential role in modulating the gut microbiome balance, which is essential for preventing dysbiosis—a condition linked to various gastrointestinal disorders. Understanding the function of M. intestinale may also provide insights into how specific gut microbes can be leveraged to enhance gut health or develop probiotic therapies for managing gut-related diseases in both humans and animals. |
