Microbe Identification
Microbe nameAlistipes indistinctus
NCBI Taxonomy ID626932
DescriptionAlistipes indistinctus is a Gram-negative, rod-shaped bacterium that thrives in mesophilic temperatures, categorized as a Chemoheterotroph, and can be found in various body sites, including the gut, skin, and respiratory tract, across different species. As an Obligate Anaerobe, Alistipes indistinctus requires the absence of oxygen to grow and survive. The Gram-negative characteristic indicates that the bacterium has a thin peptidoglycan layer in its cell wall, making it more resistant to certain antibiotics. Its rod-shaped morphology allows it to maintain a large surface area, facilitating the absorption of nutrients from its environment. As a mesophilic microorganism, Alistipes indistinctus grows best in moderate temperatures, typically between 20-45°C, which is ideal for its survival in the human body.As a Chemoheterotroph, Alistipes indistinctus relies on chemical compounds for energy and organic compounds for carbon, breaking down complex molecules into simpler ones to sustain its growth. The bacterium's presence in various body sites, including the gut, skin, and respiratory tract, suggests its ability to adapt to different environments and host-microbe interactions. The absence of oxygen is crucial for its growth, as it is unable to survive in aerobic conditions. Alistipes indistinctus plays a significant role in the human microbiome, particularly in the gut, where it contributes to the breakdown of complex carbohydrates and produces short-chain fatty acids, which can influence host health and disease. Research has shown that an imbalance of Alistipes indistinctus in the gut microbiome has been linked to various diseases, including inflammatory bowel disease and obesity, highlighting the importance of this microbe in maintaining a healthy balance in the human body.
