| Description | Bacteroides intestinalis is a gram-negative, rod-shaped microbe that is mesophilic, thriving in moderate temperatures, and is a chemoheterotroph, requiring organic compounds for energy and growth, which can be found in various body sites including the gut, mouth, and skin of humans and animals. As a gram-negative bacterium, Bacteroides intestinalis has a unique outer membrane structure that plays a crucial role in its ability to interact with its environment and evade the host's immune system. Its rod-shaped morphology allows it to maintain a large surface area, facilitating the uptake of nutrients and adherence to surfaces. As a mesophilic microbe, Bacteroides intestinalis grows best in temperatures between 20-45°C, making it well-suited to the human body's normal temperature range. As a chemoheterotroph, it relies on the breakdown of complex organic molecules to obtain energy, which is reflected in its ability to degrade a wide range of polysaccharides and proteins. Bacteroides intestinalis is an obligate anaerobe, requiring the absence of oxygen to survive and grow, which is why it is typically found in environments with low oxygen levels, such as the gut. This microbe plays a crucial role in the digestion and fermentation of complex carbohydrates in the gut, producing short-chain fatty acids that provide energy to the host. The unique combination of characteristics in Bacteroides intestinalis allows it to thrive in a variety of environments, from the human gut to the soil and sediment of aquatic ecosystems, where it contributes to the degradation of organic matter and the cycling of nutrients. Bacteroides intestinalis has been shown to produce certain enzymes that can break down and inactivate certain antibiotics, making it a subject of research in the development of new antimicrobial therapies. |
