Microbe Identification
Microbe nameBarnesiella intestinihominis
NCBI Taxonomy ID487174
DescriptionBarnesiella intestinihominis 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 gastrointestinal tract, of numerous species, including humans. As a chemoheterotroph, B. intestinihominis relies on organic compounds for energy and carbon, breaking down complex molecules to sustain its growth. This microbe is an obligate anaerobe, requiring the absence of oxygen to survive, which is reflected in its habitat of choice, the oxygen-depleted environments of the gut. The rod-shaped morphology of B. intestinihominis allows it to navigate and colonize the intestinal mucosa, where it can exploit the abundant nutrients available. As a inhabitant of the gastrointestinal tract, B. intestinihominis has adapted to the unique conditions of this environment, including the presence of bile salts, digestive enzymes, and a diverse microbial community. Its ability to thrive in this ecosystem is likely due to its capacity to utilize a wide range of carbon sources, including carbohydrates, amino acids, and other organic compounds. The mesophilic temperature preference of B. intestinihominis allows it to grow optimally at temperatures between 20-45°C, which is consistent with the temperatures found in the human body. B. intestinihominis has been implicated in the modulation of the immune system and the maintenance of gut homeostasis, producing metabolites that can influence the activity of immune cells and the integrity of the epithelial barrier. Its presence in the gut microbiome has also been linked to the production of short-chain fatty acids, which can serve as energy sources for colonocytes and other cells in the gut. The discovery of B. intestinihominis in the gut microbiome of humans has led to a greater understanding of the complex relationships between microbes and their hosts, and has highlighted the importance of considering the microbiome in the development of novel therapeutic strategies.
