Alistipes onderdonkii

Alistipes onderdonkii is a Gram-negative, rod-shaped bacterium that thrives in mesophilic temperatures, classified as a chemoheterotroph, and can be found in various body sites including the gut, mouth, and skin of humans and animals. As an obligate anaerobe, Alistipes onderdonkii requires the absence of oxygen to survive and grow. The Gram-negative cell wall structure of this microbe contributes to its ability to evade the host's immune system, allowing it to persist in the gut and other body sites. Its rod shape is typical of many bacterial species, providing a large surface area for nutrient absorption and interactions with the host environment. As a mesophilic microbe, Alistipes onderdonkii grows best in temperatures between 20-45°C, which is consistent with the temperatures found in the human body. As a chemoheterotroph, it relies on organic compounds for energy and carbon, breaking down complex molecules into simpler ones to sustain its growth and survival. Alistipes onderdonkii can be found in the gut microbiome of healthy individuals, where it plays a role in maintaining the balance of the microbial community, and its presence has been linked to various diseases, including inflammatory bowel disease and obesity, highlighting the complex relationships between the microbiome and human health. The ability of Alistipes onderdonkii to produce short-chain fatty acids as byproducts of fermentation has been shown to have anti-inflammatory effects, which may contribute to its potential therapeutic applications.
