Bacteroides caccae

Bacteroides caccae is an obligate anaerobic, Gram-negative, rod-shaped bacterium belonging to the Bacteroidetes phylum. It is categorized as a chemoheterotroph, deriving its energy from the breakdown of organic compounds, specifically carbohydrates and proteins, in an anaerobic environment. This microbe thrives in a temperature range suitable for mesophiles, typically around 30-37°C, which aligns with the human body temperature, indicating its adaptation to the human gut environment. The shape of Bacteroides caccae is bacillus, or rod-shaped, which is characteristic of many bacteria in its genus. It is primarily found in the gastrointestinal tract of humans, where it plays a crucial role in the digestion of complex polysaccharides and the production of short-chain fatty acids, which are beneficial for gut health. Besides the gut, it can also be found in other body sites, including the oral cavity and the female genital tract, reflecting its versatility and adaptability to different environments within the human body. As a key member of the gut microbiota, Bacteroides caccae contributes to the maintenance of gut homeostasis and immune function. It participates in the fermentation of dietary fibers, producing metabolites that can influence host metabolism and immune responses. Additionally, this bacterium has been the subject of research concerning its potential role in health and disease, with emerging evidence suggesting that imbalances in its abundance may be linked to conditions such as obesity, inflammatory bowel disease, and other metabolic disorders. Its ability to metabolize diverse substrates underscores the importance of maintaining a balanced gut microbiome for overall health.
