| Description | Eubacterium infirmum is a Gram-positive, rod-shaped microbe that thrives in mesophilic temperatures, categorizing it as a chemoheterotroph, and can be found in various body sites, including the gastrointestinal tract, skin, and respiratory tract, across different species. As an obligate anaerobe, Eubacterium infirmum requires the absence of oxygen to survive, which is reflected in its metabolic processes. The Gram-positive cell wall provides structural support and maintains the cell's shape, while its rod-shaped morphology allows for efficient absorption of nutrients.The mesophilic temperature preference of Eubacterium infirmum indicates that it grows best in moderate temperatures, typically between 20-45°C, which is consistent with its presence in the human body. As a chemoheterotroph, Eubacterium infirmum relies on organic compounds for energy and carbon, breaking down complex molecules into simpler ones to sustain its growth. Its widespread distribution across different body sites and species suggests a high degree of adaptability and ability to colonize various environments. The absence of oxygen is crucial for the survival of Eubacterium infirmum, as it lacks the necessary mechanisms to detoxify reactive oxygen species. This limitation restricts its habitat to anaerobic environments, such as the gut or deep tissues. Eubacterium infirmum has been implicated in the degradation of complex polysaccharides and production of short-chain fatty acids, which can influence the host's metabolism and overall health. The ability of Eubacterium infirmum to produce antimicrobial compounds has also been observed, which may contribute to its competitive advantage in colonizing diverse environments. |
