| Description | Brevundimonas bacteroides is a Gram-negative, rod-shaped bacterium that thrives at mesophilic temperatures, classified as a chemoheterotroph, and is typically categorized as a facultative anaerobe. This versatile microorganism has been isolated from various body sites, including human skin, the digestive tract, and mucosal surfaces, indicating its presence in both benign and pathogenic contexts. As a Gram-negative organism, Brevundimonas bacteroides possesses a thin peptidoglycan layer surrounded by an outer membrane that contains lipopolysaccharides, which can provoke immune responses in hosts. The rod shape enhances its ability to colonize diverse environments, facilitating motility and adherence to surfaces, critical for its survival in competitive microbial communities. Being a mesophilic organism, it grows optimally at moderate temperatures, aligning with the typical conditions found in the human body, which fosters its prevalence in numerous body sites. As a chemoheterotroph, B. bacteroides relies on organic compounds for energy and carbon, often utilizing a wide range of substrates derived from the host’s diet or other microbial metabolism. As a facultative anaerobe, this microbe exhibits metabolic flexibility, allowing it to adapt to varying oxygen levels. It can thrive in oxygen-rich environments, utilizing aerobic respiration, but can also switch to fermentation pathways when oxygen is limited, enabling colonization in anaerobic niches within the host. Notably, Brevundimonas bacteroides has attracted attention for its potential role in human health. Its interactions with the human microbiome suggest it may contribute to maintaining gut health and influencing immune system function. Additionally, this microbe has been studied for its capacity to degrade complex organic compounds, showing promise in bioremediation applications. |
