Bacteroides fragilis
Research Article | Molecular Biology and PhysiologyGenetic and Biochemical Analysis of Anaerobic Respiration in Bacteroides fragilis and Its Importance In VivoBacteroides species are abundant in the human intestine and provide numerous beneficial properties to their hosts. The ability of Bacteroides species to convert host and dietary glycans and polysaccharides to energy is paramount to their success in the human gut. We know a great deal about the molecules that these bacteria extract from the human gut but much less about how they convert those molecules into energy. Here...
- Research ArticleGut Symbiont Bacteroides fragilis Secretes a Eukaryotic-Like Ubiquitin Protein That Mediates Intraspecies Antagonism
We are just beginning to understand some of the important interactions that occur between microbes of the human gut microbiota that dictate the composition and abundance of its constituent members. The ability of one member to produce molecules that directly kill a coresident member has been shown among minor gut species and is just starting to be studied in the abundant Bacteroides species. Here, we show that some strains of...
