| Description | Bacteroides finegoldii is a gram-negative, rod-shaped microbe that thrives in mesophilic temperatures, categorizing it as a chemoheterotroph, and can be found in various body sites, including the gut, mouth, and skin, across different species. As an obligate anaerobe, Bacteroides finegoldii requires the absence of oxygen to survive and grow, which is a crucial aspect of its biology. The gram-negative characteristic of Bacteroides finegoldii refers to its cell wall structure, which consists of a thin peptidoglycan layer and an outer membrane containing lipopolysaccharides. Its rod-shaped morphology is typical of many bacteria, allowing for efficient movement and nutrient uptake. The mesophilic temperature preference of Bacteroides finegoldii 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, Bacteroides finegoldii relies on organic compounds for energy and carbon, breaking down complex molecules into simpler ones to sustain its growth and survival. Its presence in various body sites, including the gut, mouth, and skin, highlights its ability to adapt to different environments and host-microbe interactions. The obligate anaerobic nature of Bacteroides finegoldii means that it has evolved to thrive in oxygen-free conditions, using alternative metabolic pathways to generate energy. Bacteroides finegoldii plays a significant role in the human microbiome, particularly in the gut, where it contributes to the breakdown of complex polysaccharides and production of short-chain fatty acids, which are essential for maintaining a healthy gut epithelium. Its unique metabolic capabilities and strict anaerobic requirements make it an important subject of study in the field of microbiology, and recent research has shown that Bacteroides finegoldii can produce antimicrobial compounds that inhibit the growth of other microbes, potentially contributing to its ability to colonize and persist in the human body. |
