| Description | Eggerthella sp. YY7918 is a Gram-negative, rod-shaped bacterium that thrives in a temperature range of 30-40°C, categorized as a mesophile. It is a chemoorganotroph, meaning it obtains energy by oxidizing organic compounds, specifically glucose, to produce ATP. The process of glucose oxidation occurs through the Embden-Meyerhof-Parnas pathway, a common metabolic pathway found in many microorganisms. As a Gram-negative bacterium, Eggerthella sp. YY7918 has a thin peptidoglycan layer and an outer membrane, which is notable for its lipopolysaccharide-rich composition. Rod-shaped bacteria like this species are typically 0.5-1.5 μm in length and 0.3-0.5 μm in width. This microbe can be found in various body sites, including the human gut, where it likely plays a role in the breakdown of complex carbohydrates. The presence of Eggerthella sp. YY7918 has been detected in the oral cavity, respiratory tract, and skin, highlighting its adaptability to different environmental conditions. Eggerthella sp. YY7918 is an obligate anaerobe, meaning it is unable to survive in the presence of oxygen. Its metabolic processes are optimized for low-oxygen conditions, which is likely due to its ability to thrive in the oxygen-poor environments of the human gut and other body sites. In addition to its unique characteristics, Eggerthella sp. YY7918 has been found to produce exopolysaccharides, which are complex carbohydrates that can influence the host's immune system. Furthermore, research has shown that this microbe may play a role in the development of diseases such as periodontitis and inflammatory bowel disease. As our understanding of Eggerthella sp. YY7918 continues to grow, it is likely that this microbe will be recognized as a key player in the complex interactions between the human microbiome and host. |
